概要：This research proposes a novel wireless information-centric networking (ICN) architecture, namely, Context-Aware Green ICN Model (CAGIM), which can adapt the power consumption of network nodes to optimized values according to the associated link utilization. The power adaption in ICN nodes is conducted through dynamically adjusting the link-rate corresponding to content popularity and traffic load to reduce wasteful energy consumption. Moreover, we propose a smart popularity-based caching strategy, called distinguished caching scheme (DCS), with the introduction of hot and cold-caching partitions of ICN node's cache storage for popular and non-popular content objects, respectively. DCS improves the content diversity of the cache storage by adjusting, for each content, the number of chunks to be cached at ICN nodes based on its type and popularity level. DCS thus can further decrease the network system power consumption, thanks to its improved cache hit that reduces network traffic load. Toward the goal of realizing a context-aware green wireless network system with efficient content delivery, we also design a WiFi Direct based scheme as an alternative approach to minimize power consumption and latency by sharing essential/important content objects via direct communications with power-saving mechanisms in the case that wireless local area network connections are not available. The evaluation results show that CAGIM can improve network efficiency by reducing both hop-count and power consumption considerably compared with existing wireless network systems with different well-known caching schemes. This proposal enables a flexible and efficient content delivery mechanism for future networks with various real-life scenarios, like Green building, Green company, and Green campus content accesses.

概要：By considering the definitions and properties from the field of linguistics regarding place specification, a questionnaire that can be used to improve naming in networks is obtained. The questionnaire helps introduce the idea of place specification from linguistics and the concept of metric spaces into network naming schemes. The questionnaire results are used to improve the basic Information-Centric Networking (ICN) architecture’s notoriously lax network naming structure. The improvements are realized by leveraging components from the Named-Node Network Architecture, a minor ICN design, to supply the resulting network architecture with the properties the questionnaire highlights. Evaluation results from experiments demonstrate that modifying the network architecture so that the proposed questionnaire is satisfied results in achieving high mobility performance. Specifically, the proposed system can obtain mean application goodput at above 88% of the ideal result, with a delay below 0.104 s and with the network time-out Interest ratio below 0.082 for the proposed single mobile push producer, single mobile consumer scenario, even when the nodes reach the maximum tested speed of 14 m/s.

概要：Single-sideband (SSB) modulation through Hilbert transformation has successfully transmitted data using only half the bandwidth of the traditional scheme for the same amount of contained information. Toward this end, the four single-sideband (4-SSB) approach for high order modulation is a promising approach for the next-generation communications by applying soft-input soft-output (SISO) equalizer algorithms over orthogonal frequency division multiplexing (OFDM). However, OFDM is challenging for realizing the feasible 5G communications, compared to the emerging techniques, e.g., non-orthogonal multiple access (NOMA), orthogonal multiple access (OMA) or multiple-input multiple-output (MIMO). Since the 4-SSB is an orthogonal modulation which was successfully applied over the traditional OFDM, in this article, we propose a novel 4-SSB modulation scheme over OFDM Guard Interval (GI) and massive MIMO. Besides the carrier signal, from the receiver side, we also apply the shadow equalizer algorithm in the uncoded and coded environment using turbo codes to achieve the 4-SSB with high efficiency from low complexity and energy consumption for 5G. The evaluation results validate that our system consumes lower energy due to low complexity gained from same number of iterations without the heavy decoding as of the 4-SSB SISO based on the turbo equalizer. In addition, the 4-SSB over the OFDM GI achieves the best performance among the relevant approaches conducted in 4-SSB. The proposal then acts as a practical communication system designed to solve the inter-symbol interference (ISI) induced by additional Hilbert transform in the wireless environment toward fifth generation (5G), given that turbo code is considered as a potential channel coding scheme for 5G radio specification.

概要：In this research, we leverage the emerging concept of network slicing to enable the end- to-end integrated Information-Centric Networking (ICN) and Content Delivery Network (CDN) for 5G networking infrastructure. While CDN is deployed to cache content at the optimal server correspondin g to the content and geographical location, this paper focuses on verifying the efficiency of ICN slice for regional content distribution. Specifically, the ICN slice can be established by the regional Orchestrator by following the current NFV/SDN standard. Then, the slice stitching process will be performed to interconnect two slices after their establishments via the Orchestrator. We also implement an OpenStackbased virtual node which supports both IP and ICN protocols and acts as the ICN-Gateway. The joint-testbed evaluations conducted between Japan side (ICN slice) and Europe side (CDN slice) show that the deployment of ICN Gateway and the proposed Node ID-based ICN naming structure can improve network performance and avoid network congestion.

概要：This article proposes a novel chunk-based caching scheme known as the Progressive Popularity-Aware Caching Scheme (PPCS) to improve content availability and eliminate the cache redundancy issue of Information-Centric Networking (ICN). Particularly, the proposal considers both entire-object caching and partial-progressive caching for popular and non-popular content objects, respectively. In the case that the content is not popular enough, PPCS first caches initial chunks of the content at the edge node and then progressively continues caching subsequent chunks at upstream Content Nodes (CNs) along the delivery path over time, according to the content popularity and each CN position. Therefore, PPCS efficiently avoids wasting cache space for storing on-path content duplicates and improves cache diversity by allowing no more than one replica of a specified content to be cached. To enable a complete ICN caching solution for communication networks, we also propose an autonomous replacement policy to optimize the cache utilization by maximizing the utility of each CN from caching content items. By simulation, we show that PPCS, utilizing edge-computing for the joint optimization of caching decision and replacement policies, considerably outperforms relevant existing ICN caching strategies in terms of latency (number of hops), cache redundancy, and content availability (hit rate), especially when the CN’s cache size is small.

概要：Information-Centric Networking (ICN) is a new Internet architecture design, which is considered as the global-scale Future Internet (FI) paradigm. Though ICN offers considerable benefits over the existing IP-based Internet architecture, its practical deployment in real life still has many challenges, especially in the case of high congestion and limited power in a sensor enabled-network for the Internet of Things (IoT) era. In this paper, we propose a smart congestion control mechanism to diminish the network congestion rate, reduce sensor power consumptions, and enhance the network performance of ICN at the same time to realize a complete green and efficient ICN-based sensor networking model. The proposed network system uses the chunk-by-chunk aggregated packets according to the content popularity to diminish the number of exchanged packets needed for data transmission. We also design the sensor power-based cache management strategy, and an adaptive Markov-based sensor scheduling policy with selective sensing algorithm to further maximize power savings for the sensors. The evaluation results using ndnSIM (a widely-used ICN simulator) show that the proposed model can provide higher network performance efficiency with lower energy consumption for the future Internet by achieving higher throughput with higher cache hit rate and lower Interest packet drop rate as we increase the number of IoT sensors in ICN.

概要：In this article, we leverage Network Function Virtualization (NFV) and Multi-Access Edge Computing (MEC) technologies, proposing a system which integrates ICN (InformationCentric Network) with CDN (Content Delivery Network) to provide an efficient content delivery service. The proposed system combines the dynamic CDN slicing concept with the NDN (Named Data Network) based ICN slicing concept to avoid core network congestion. A dynamic CDN slice is deployed to cache content at optimal locations depending on the nature of the content and the geographical distributions of potential viewers. Virtual cache servers, along with supporting virtual transcoders, are placed across a cloud belonging to multiple-administrative domains, forming a CDN slice. The ICN slice is, in turn, used for the regional distribution of content, leveraging the namebased access and the autonomic in-network content caching. This enables the delivery of content from nearby network nodes, avoiding the duplicate transfer of content and also ensuring shorter response times. Our experiments demonstrate that integrated ICN/CDN is better than traditional CDN in almost all aspects, including service scalability, reliability, and quality of service.

概要：Information-Centric Vehicular Networking (ICVN) is a paradigm shift in vehicular communication which implements self-content management to eliminates issues related to the current host-based IP network. Due to the exponential growth in demands of multimedia services, current vehicular networks face several challenges to support mobility with optimal Quality of Service (QoS). To achieve the high QoS performance, an intelligent vehicular network service with dynamic control mechanisms is necessary. This motivates the development of dynamic content management that implements an intelligence architecture. The proposed intelligent architecture comprised of two primary stages: classifications and discovery. In the first stage, a classifier system categorizes the user’s content request and the second stage presents an adaptive forwarding path discovery towards the nearest content provider. Here, a Rule-based Evolutionary Systems (RES) agent performs exploration and exploitation to discover every possible forwarding path in the heterogeneous network. The agent then performs the discovery action that is guided by the variance introduced in the Reinforcement Learning (RL) policy. The simulation results confirms the suitability and scalability of the proposed architecture, particularly in reducing data packet delivery time, increasing data transfer rate, improve interest success rate, and lower the network traffic by 70%, 28%, 24% and 65% respectively.

概要：This research proposes an intelligent classification framework for quality of service (QoS) performance improvement in information-centric networking (ICN). The proposal works towards keyword classification techniques to obtain the most valuable information via suitable content prefixes in ICN. In this study, we have achieved the intelligent function using Artificial Intelligence (AI) implementation. Particularly, to find the most suitable and promising intelligent approach for maintaining QoS matrices, we have evaluated various AI algorithms, including evolutionary algorithms (EA), swarm intelligence (SI), and machine learning (ML) by using the cost function to assess their classification performances. With the goal of enabling a complete ICN prefix classification solution, we also propose a hybrid implementation to optimize classification performances by integration of relevant AI algorithms. This hybrid mechanism searches for a final minimum structure to prevent the local optima from happening. By simulation, the evaluation results show that the proposal outperforms EA and ML in terms of network resource utilization and response delay for QoS performance optimization.

概要：The Single Sideband (SSB) modulation through Hilbert transformation has successfully transmitted data using only half bandwidth for the same amount of contained information. Towards this line, the Four Single SideBand (4-SSB) using QPSK modulation over OFDM was proposed as a new applicable modulation for the next generation communication system, such as 5G. This approach can improve the network efficiency, however, the InterSymbol Interference (ISI) is substantially introduced in 4-SSB based modulation due to the wireless channel characteristics, especially when we are increasing the order of modulation. Particularly, the Widely Linear Minimum Mean Squared Error (MMSE) equalizer is impractical in high order modulation because of its high performance degradation. In this paper, we propose a 4-SSB M-QAM over OFDM approach to improve the modulation feasibility and data rate, compared to the previous 4-SSB using QPSK over OFDM. The proposal uses the Infinite Length MMSE Soft Input Soft Output (SISO) equalizer to deal with ISI induced by the Finite Impulse Response (FIR) of the Hilbert transform filter. The evaluation results show that the proposed 4-SSB-based modulation technique using MMSE SISO equalizer can considerably reduce the effect of ISI in non-ideal environments, including the Additive White Gaussian Noise (AWGN) and fading channel.

概要：Codebook-based beamforming is used in millimeter wave communications to alleviate the difficuity of obtaining accurate channel state information (CSI) for large antenna arrays. However, the required codebook size is usually large thus codebook search becomes computationally prohibitive due to its exponential growth. To address this, we propose a direct search technique with the concept of tracking the strong beam stream based on the recently proposed global direct search (GDS) optimization method. Simulation results show that our beam training technique achieves a near-optimal performance (about 97% as that of the exhaustive search) at much lower complexity levels.

概要：Network congestion control is an important criterion to evaluate the network performance. This is a major research challenge in ICN (Information-Centric Networking), especially in the case of high congestion in a Sensor Network for the IoT (Internet of Things). The reason is that the content producers in ICN need to reply a huge number of content requests from the consumers. In this paper, we propose a hierarchical ICN model for IoT sensor network with dynamic congestion control mechanism. The proposed network system transmits the content with content popularity and priority-based delay time, together with adaptive content lifetime and cache management strategy. The evaluation results using ndnSIM show that the proposed model can provide higher network performance efficiency for the future Internet by achieving higher throughput with lower Interest packet drop rate and higher cache hit rate as we increase the number of IoT sensors in ICN.

概要：In Information Centric Networking (ICN), on-path caching is an integrated caching solution with-in an Autonomous System's (AS) local network. However, it is seen that in on-path caching, the content is cached en-route in the reverse path towards the Interest generator. Thus, local Rendezvous Network (RENE)/Name Resolution System (NRS)(in routing through name resolution) or FIB (in name-based routing) is not conscious of the cached data. Therefore, the most extensively deployed intra-domain routing protocol and their forwarding strategy is not capable of addressing all available temporary cached copies of the content. Hence, on-path caching strategy experiences two major downsides: numerous replicas of same content within AS without adding significant value in terms of cache resource utilization and an approach taken to minimize redundancy ends up with the cost of fetching more copy of similar content. In this paper, we introduce an integrated caching and forwarding solution which minimizes the caching redundancy and maximizes the probability of finding nearby cached content. We leverage Name Data Networking (NDN) node architecture and its forwarding plane/strategy (of routing) to attain our goal. Mathematical analysis to determine load balance and cache hit ratio, and simulation results considering average hopdistance and server hit ratio authenticate the efficiency of our proposed scheme.

概要：Nowadays, Internet is mostly used to access content and users are also interested in content, instead of location. Information-Centric Networking (ICN) has drawn substantial consideration over past few years because its appearance introduced a new potential Internet architecture (deploying extensive cache structure to distribute and deliver information). Though ICN has undoubtedly become a promising Future Internet architecture to solve current host-centric Internet problems, conventional ICN design still has its own drawbacks. These include caching, routing, etc., particularly mobility issue and energy-efficiency problem due to additional energy consumption for Content Routers’ caching capability. In order to address the energy flaw and enhance the mobility performance of ICN Architecture, in this article, we have designed, evaluated and proposed a wireless Information Centric Networking (ICN) based access model within the context of Intelligent Transport System (ITS) for ICN standardization procedure. We take into consideration the fact that number of mobile devices increases rapidly day by day as well as the public transportation (e.g. train, bus, etc) becomes more popular nowadays. Besides, mobile users may ask for different content interests via Internet during the period of time when they are on public transport vehicle. We then propose a wireless communication topology in ICN for the ITS by utilizing the smart scheduling algorithm with proactive-caching based strategy to deal with possible and practical situations of commuters (mobile content users). In our scheme, the dedicated content provider proactively sends appropriate segments of requested content (based on chunk-level structure of content) to expected proximity Aggregation content nodes located at neighbor stations (future attachment points) on the moving path of public transportation vehicle. This working scheme substantially enhances the mobile user’s quality of experience and network performance in ICN. Moreover, the proposed ICN based system adapts the network nodes to their optimized network utilization values according to content popularity by conducting cross-layer optimization. This mechanism provides mobile users more reliable and effective Green Information and Communication Systems (ICS) when they travel with public transportation. Therefore, the proposal integrates Green networking into ICN by combining the benefits of innovated rate-adaptivity and proactive-caching based schemes for achieving highly scalable, reliable and energy-efficient network performance in future transportation Information-centric communication system with data-awareness. In addition, we identify that there are currently various ICN-based models and emphasize the need of an official ICN international standard for wireless communication in general and transportation system in particular. Following, by evaluating the proposal, we show that the proposed cross-layer wireless content access model in ICN for ITS is a promising and feasible contribution for the standardization process of ICN.

概要：Home network (HOMENET) performs multiple important functions such as energy management, multimedia sharing, lighting and climate control in smart grid (SG). In HOMENET there are numerous challenges among which mobility and security are the basic requirements that need to be addressed with priority. The information-centric networking (ICN) is regarded as the future Internet that subscribes data in a content-centric manner irrespective of its location. Furthermore, it has pecial merit in mobility and security since ICN supports in-network caching and self-contained security, these make ICN a potential solution for home communication fabric. This paper aims to apply the ICN approach on HOMENET system, which we called ICN-HOMENET. Then, a proof-of-concept evaluation is employed to evaluate the effectiveness of the proposed ICN-HOMENET approach in data security, device mobility and efficient content distribution for developing HOMENET system in SG. In addition, we proposed a cost-efficient residential energy management (REM) scheme called ICN-REM scheme for ICN-HOMENET system which encourages consumers to shift the start time of appliances from peak hours to off-peak hours to reduce the energy bills. To the best of our knowledge, this is the first attempt to propose an ICN-based REM scheme for HOMENET system. In this proposal, we not only consider the conflicting requests from appliances and domestic power generation, but also think the energy management unit (EMU) should cooperate with measurement sensors to control some specific appliances in some specific conditions. Moreover, the corresponding performance evaluation validates its correctness and effectiveness.

概要：In Information Centric Networking (ICN), besides Off-path caching, On-path caching is an integrated caching solution with-in an ISP's local network. However, in On-path caching, content is cached en-route in the backward path towards the Interest generator and local RENE1/NRS2 (in routing through name resolution) or FIB3 (in name-based routing) is not aware of the cached data. Hence, the most widely used intra-domain routing protocol and their forwarding strategy cannot address all available temporary cached copies of content. Thus, on-path caching strategy usually suffers from either of the two drawbacks- (1) too many replications within AS (Autonomous system) which do not add substantial value in terms of cache resource utilization. (2) An attempt to minimize redundancy ends up with the cost of fetching more copy of the same content from the repository (i.e., the closest cache copy is unknown/ not en-route). We propose an integrated routing and caching solution which reduces the caching redundancy and maximize the probability of finding nearby cached content, resulting in efficient utilization of available cache resources of ISP's as a whole. We introduce novel concepts of naming the content router and caching the content's cache-route to address the issue. We leverage NDN node architecture and the forwarding plane/strategy (of routing) as well to achieve our goal.

概要：In order to address the energy flaw and enhance the energy efficiency of Information Centric Networking (ICN) Architecture, this research proposes an innovated optimal ICN model with adaptive power consumption ability based on the popularity of the content to adapt content router link rate to its real-time utilization for optimizing the ICN router operating power value and based on the interest traffic to the server to select the optimal working mode for the server/content provider. With this dynamic control/adaptive mechanism, the proposed architecture can provide higher reliability with dynamic energy efficiency consumption and better cost-effectiveness for the future ICN infrastructure system to reduce electricity usage, cost and greenhouse gases, then solve global warming issues.

概要：In order to study the application and benefit of Sensor Network in Information Centric Networking (ICN) for the Internet of Things (IoT) era, in this paper, we propose a tree-based ICN model utilizing the sensors to complete the transactions in network. We simulate the proposed model using ndnSIM and the evaluation results show that all the performance metrics, including the number of packets, total run time and average throughput substantial increase as we increase number of sensors in the network.

概要：In order to provide the robust and energy-efficiency contents delivery to the mobile terminals in Information Centric Networking (ICN), this paper proposes a dynamic proactive-scheme and evaluates its performance as an effective mechanism for green mobility in ICN. In our scheme, when a mobile node expresses an Interest for a content then neighbor Aggregation Nodes (possible future points of attachment) also generate the" fake interest" for this content to the Content Provider. As a result, after the handoff, when the mobile node re-issues the same interest, the desired content can be found en-route and can be retrieved immediately. To diminish the ICN energy consumption by utilizing this scheme (the interest needs not to travel to the Content Server), we design different operating modes for the server based on the interest traffic. We verify the effectiveness and reliability of our proposed scheme by simulating the model with ndnSIM.

概要： The appearance of Information-Centric Networking (ICN) has drawn substantial considerations over the recent years as a promising Future Internet (FI) design. Particularly, thanks to the in-network caching and naming schemes, ICN provides a built-in security feature and focuses on content dissemination to improve key network metrics compared to the existing IP-based Internet. However, currently, little attention has been carried out to address the feasibility of in-network caching in Information-Centric Networking (ICN) for the design and real-world deployment of future networks. Towards this line, in this talk, I propose a beneficial caching scheme in ICN by storing no more than a specific number of replicas for each content. Particularly, to realize an optimal content distribution for deploying caches in ICN, a content can be cached either partially or as a full-object corresponding to its request arrival rate and data traffic. Also, I employ a utility-based replacement in each content node to keep the most recent and popular content items in the ICN interconnections. Then I will show how the proposal improves the cache hit rate and cache diversity considerably, and acts as a beneficial caching approach for network and service providers in ICN. Specifically, the proposal demonstrates that a large amount of network resource is ineffective and can be saved, especially when the network scale gets larger. The proposed beneficial caching scheme then efficiently utilizes the content node’s valuable and limited cache resource for deserved-to-be cached content items to diminish the number of packets transmitting to higher level nodes and the content source. Also, the proposed caching mechanism is easy to deploy, robust, and relevant for the content-based providers by enabling them to offer users high Quality of Service (QoS) and gain benefits at the same time, then realizes new potential services for the service provider networks.

The power adaption in ICN nodes is conducted through dynamically adjusting the link-rate corresponding to content popularity and traffic load to reduce wasteful energy consumption. Moreover, we propose a smart popularity-based caching strategy, called distinguished caching scheme (DCS), with the introduction of hot and cold-caching partitions of ICN node's cache storage for popular and non-popular content objects, respectively. DCS improves the content diversity of the cache storage by adjusting, for each content, the number of chunks to be cached at ICN nodes based on its type and popularity level. DCS thus can further decrease the network system power consumption, thanks to its improved cache hit that reduces network traffic load. Toward the goal of realizing a context-aware green wireless network system with efficient content delivery, we also design a WiFi Direct based scheme as an alternative approach to minimize power consumption and latency by sharing essential/important content objects via direct communications with power-saving mechanisms in the case that wireless local area network connections are not available.

The cross-layer power adaption is conducted through adjusting link rate dynamically according to the content popularity to reduce wasteful power consumption of content nodes. Moreover, wepropose an intelligent caching scheme, in which the caching portion is adjustedbased on the content popularity and available space of each node. Regarding theNetwork slicing architecture, each slice provides a dedicated networkingsolution that matches specific applications. Particularly, each slice has single or multiple services, and the UE (User Equipment) can attach to multiple slices and request the creation of a slice for real-time services like live eventstreaming. To enable dynamic content delivery and VNF (Virtual NetworkFunction) allocation, the network-slicing framework realizes slice stitchingmechanism which allows one slice to interact with another slice viamulti-domain orchestration with scalable slice management.
