    Current IaaS (infrastructure as a service) cloud service may not satisfy communication QoS (quality of service) requirements of delay-sensitive network applications, if there is a significant physical distance between a server of the network application (NetApp server) at a data center and its network application clients (NetApp clients). In order to improve communication QoS of NetApp clients, we propose server migration service (SMS) in this article. SMS allows NetApp servers to migrate among different locations in the network (1) to optimally locate themselves in relation to NetApp clients and mitigate the QoS degradation caused by location-related factors (ie, propagation delays on network links) and (2) to optimally distribute traffic load over routers and processing load over (physical) computers and decrease the energy consumption. We develop a mixed-integer programming model that determines when and to which locations NetApp servers migrate to minimize the total operating cost of SMS, that is, the sum of the monetary penalty incurred due to QoS violation and energy cost incurred due to energy consumption, while preventing NetApp servers from excessively migrating and adversely impacting QoS of the non-SMS service that share the resource of the substrate network with SMS. Simulation results show that the model developed in this article achieves up to 42% lower total operating cost of SMS compared to the model that only minimizes the monetary penalty of SMS without considering the energy cost of SMS.

    We propose an optimal user selection method on mobility control for ad hoc networks to improve QoS. In the proposed method, the best user, which is the best movable user for QoS, is selected based on physical distances between users in an ad hoc network and on the connection relationships between the users. The method also indicates the best destination to move that user to within a reasonable time. To reduce the search cost to obtain the best destination, the proposed method reduces the areas to be searched by identifying the discrete positions where transmission rates change according to the measurement data model. All the identified positions are examined to determine whether to relay another user to determine the best position. The evaluation results show that the proposed method achieved 99.0% of the maximum throughput obtained by moving the best user to the best destination. Throughput improvement of 10.3% was achieved compared with the conventional user mobility control method, which adopts a heuristic approach. Although the proposed method requires more running time than the conventional heuristic approach, it remains within a reasonable time.

    By enabling direct communications between nearby user equipment (UE), device-to-device (D2D) communication has become one of the key technologies in 5th generation (5G) mobile networks. D2D communication brings new communication opportunities for mobile devices, especially in a highly dense network. In this paper, D2D communication in the unlicensed spectrum, namely, D2DUnlicensed (D2D-U), is discussed. The use of unlicensed frequency bands can ease the shortage of spectrum resources and improve network performance. However, the D2D-U in 5G has significant effects on the network performance of existing unlicensed networks sharing the same frequency bands, such as Wi-Fi and Bluetooth. Therefore, it is necessary to design a fair coexistence scheme for D2D-U. To understand the coexistence problem, in this paper, we first formulate the network performance of D2DU and Wi-Fi under two different coexistence schemes, namely, listen before talk (LBT) and duty cycle mechanism (DCM). Then, we use computer simulations to investigate a mode selection scheme that switches between these two schemes and point out the best possible solution for the coexistence between D2D-U and Wi-Fi.

    We propose a method to improve Quality of Service (QoS) between the IEEE802.11 AP (access point) and the AMR by using a neighboring AMR as a relay communication node. We assume a self-driving small vehicle as an AMR (Autonomous Mobile Robot) such as auto-driving wheelchair, which drives to an on-demand destination. The proposed method consists of a midpoint-following route control method and a relay control method. In the midpoint-following route control method, neighboring AMRs (Contribution-AMRs, C-AMRs) move in the direction of the midpoint between its AP and a moving AMR (Benefit-AMR, B-AMR). Then, the C-AMR could relay the B-AMR to the AP for better QoS. The relay control method decides whether to use the relay or not depending on estimations of throughput based on positions of B-AMRs, C-AMRs and APs. The proposed route control obtains semi-optimal move for a C-AMR and also obtains the highest throughput for a B-AMR. Because an initial position of the C-AMR significantly effects on QoS, QoS characteristics is discussed with the initial position.

    With the large-scale mobile Internet promotion, people frequently use social applications, such as Facebook, Instagram, etc., making the social network a valuable research subject in Device-to-Device (D2D) communication. Maintaining high throughput and quality of service (QoS) are vital metrics worthy of exploration. This paper proposes a social-relay ad hoc network model based on multi-user cooperative mobility, consisting of two issues: relay selection scheme and multi- user cooperative mobility strategy. To ensure link stability in the relay selection scheme, we jointly consider social links' requirements and the probability of successful data transmission in the physical layer. Since the optimization problem is NP- hard, with game theory, we define two strategic games that include relay selection game (RSG) and multi-user mobility game (MMG), to obtain the optimal relay and the best mobility strategy for maximizing throughput. The numerical results show that the proposed potential-game approach yields 13.93%, 81.78%, and 240.83% throughput gain over the previous mid-point selection scheme, random relaying and mobility, and direct transmission, respectively.

    As the Internet of Things (IoT) has become a widespread phenomenon, promising sensor applications at the nanoscale have begun to emerge. One example is imaging via distributed massive nanoscale nodes (NSNs), which can be used to implement “invisible surveillance cameras” by, for example, painting liquids containing nanoscale sensors onto walls. This imaging method requires periodic data transfer from thousands of NSNs to a data collection node (DCN). An essential technique for handling such transfers is the media access control (MAC) protocol. However, existing protocols cannot support periodic transfer from numerous NSNs because of inefficient communication caused by a large amount of headers in the packets. In this paper, we introduce an original MAC protocol and discuss its capability in terms of implementing imaging applications. The proposed protocol applies a time-division access feature to reduce the amount of headers and a two-layered protocol to enable simultaneous transmission among nodes. Slot assignment is an essential function in time-division access and requires communication among nodes. Unlike existing methods, our simple approach enables communication by exploiting the unique features of the focused application. The results of the numerical simulation reveal that the proposed MAC protocol allows for periodic imaging with more than three thousand nodes and produces high-quality images very close to those obtained using ideal communication. These results are achieved by employing an original design framework to determine appropriate key parameters, such as number of clusters and frame rate.

    In this paper, we propose and evaluate a user-selective mobility control method to improve communication performance in social ad hoc networks. In the network, the connected user depends on the relationship among users and the dynamic routing that optimizes the quality of service. The proposed method is a heuristic method that identifies the movable users and determines the user mobility direction regarding connection and location relationships. The three selected movable users are the user with a maximum number of connectable users, the user with a maximum number of connected users, and the farthest distance connected user. The direction of the user's mobility is the direction of the center of the region consisting of connectable users. The effectiveness of the proposed method is evaluated by comparing the throughput improvement and accuracy against throughput improvement at the optimal location. The calculated throughput improvement was 1.52 and the accuracy was 0.90 when the user with a maximum number of connectable users was moved by 20 meters. The throughput improvement was 1.15 and the accuracy was 0.83 when the user with a maximum number of connected users was moved by 15 meters. The throughput improvement was 1.22 and the accuracy was 0.75 when the farthest distance connected user was moved by 20 meters.

    This paper proposes a probabilistic cooperative transmission scheme with non-orthogonal multiple access (NOMA), named NO-ProbReM, for the PC5-based cellular-vehicle-to-everything (C-V2X) mode 4 in the crash warning system (CWS). In the proposed method, each node probabilistically selects a packet based on its cooperation ability under a limited cooperation power level, which is assigned within the total transmission power limit; then, the node superposes its own packet signal and the selected packet signal on a NOMA basis. The proposed probabilistic mechanism autonomously improves the link reliability within a specific range by the limited-assigned cooperation power while guaranteeing that the direct link is sufficiently similar reliability to mode 4. Our simulation results demonstrated that with suitable parameters, the proposed method mitigated the potential channel congestion of the current mode 4; in particular, the proposed method provided 50% better performance than the current mode 4 in the fundamental node density model. These results highlight that the proposed method advanced the infrastructure-less C-V2X in the CWS.

    With the widespread adoption of the Internet of Things (IoT), throughput performance is a crucial metric in mobile ad hoc networks (MANETs) constrained by wireless bandwidth resources. Specifically, how to maximize throughput while keeping bandwidth resources constant needs to be explored. This paper investigates the optimal mobility strategy to maximize throughput in MANETs. Unlike previous studies, which mostly set a small number of fixed users and did not consider the location profiles, we jointly consider different location distributions and multiuser cooperative mobility to maximize the system throughput. On the one hand, we consider two scenarios of users' location distributions as centralized and decentralized, respectively. On the other hand, a game-theoretic approach can obtain the optimal strategy to maximize the system throughput for movable users. Numerical simulations show that the optimal cooperative mobility strategy yields 19.45% and 21.36% throughput gains over the previous intuitive approach for both location distributions.

    This paper evaluates MAC-layer delay of IEEE 802.11ad based In-vehicle communications, where strong interference from multiple devices on own and other vehicles could occur stochastically due to beamforming. The wide frequency bandwidth of IEEE 802.11ad is expected to enable ultra-low latency in-vehicle communications. However, the beamforming of IEEE 802.11ad causes strong interference and could degrade the delay performance. To investigate the impact of the beamforming interference on delay performance, we conducted network simulations using ns3. The results show that a control method, fixed contention window (CW), achieved the maximum delay of 2 msec, whereas conventional control method, Distributed Coordination Function (DCF), did larger delay of 12 msec.

    Social networks are playing an increasingly important role in information dissemination in wireless ad hoc networks with the wide adoption of the mobile Internet. In particular, in social application scenarios such as Facebook and Twitter, the questions of how to fully consider the social relationships between users to ensure the quality of service (QoS) urgently needs to be explored. This paper investigates an optimal social relay selection scheme with high intimacy requirements to maximize the system throughput for social-physical ad hoc networks with device-to-device (D2D) communication. Different from previous studies, we jointly consider feasible relays and multiuser cooperative mobility with satisfactory link reliability for throughput maximization. On the one hand, we formulate a nonlinear and nonconvex problem, which is typically NP-hard, for throughput optimization. Specifically, this optimization problem is divided into two subproblems: I) selecting the optimal relays and ii) determining the best mobility strategy in terms of throughput. On the other hand, we first convert the relay selection subproblem into an optimal stopping phase problem, and then propose a definition of a graph representing the degrees of interference between physical links, transforming the original optimization problem into a convex problem that is solvable using the Lagrange multiplier method. Based on the above, we propose the Relay selection and Link Interference Degree Graph (RS-LIDG) algorithm to solve the two subproblems. Numerical simulations verify that the proposed RS-LIDG method improves the throughput gain by 26.29%, 123.43%, and 236.47% compared to the intuitive method (IM), the social-trust-based random mobility selection method (STS-RM), and the physical-based random mobility selection method (PHS-RM), respectively.

    This paper demonstrates the feasibility of IEEE 802.11ad-based in-vehicle communication for a wireless harness. IEEE 802.11ad millimeter-wave (mmWave) communication enables high-speed wireless transmission, and its short communication range prevents harmful interference from other vehicles. However, in an in-vehicle environment, the received power of IEEE 802.11ad-based mmWave communications can be largely and easily attenuated by obstacles such as humans and the vehicle interior. Moreover, mmWave signals from adjacent vehicles can penetrate through vehicle windows and cause harmful interference. In this paper, we report the experimental results of in-vehicle communications using an actual vehicle and IEEE 802.11ad devices in an anechoic chamber. The experimental results demonstrate that IEEE 802.11ad-based in-vehicle communication can achieve a throughput of several hundred megabits per second, which is almost equivalent to that in achieved free space; this throughput can even be achieved when there are multiple obstacles in a vehicle and when adjacent vehicles (i.e., interferers) are in close proximity.

    IEEE802.11ad wireless LAN (WLAN) set in a vehicle was examined in order to know how much throughput quality was observed in congestion cases. As such a congestion case, two WLAN were used to measure throughput when vehicle frames and windows of a vehicle mitigate interference from other WLANs of other vehicles. Experiments by using real 802.11ad devices were performed and provided many useful qualitative results. For example, throughput degradation by interference is very large, 71.9% with door opened and is still large, 32.1% through glass windows. The results also revealed that steel frame doors are effective enough to shield the interference regardless of glass windows being opened or closed.

    Thanks to mobile evolution, a lot of mobile applications are used in mobile networks. Conventional mobile networks allocate radio resources to user terminals using expected throughput of each terminal and fairness between terminals. However, it becomes much more important to assure communication quality for each application under the circumstance that users are using a variety of applications. In this paper, we propose a radio resource scheduling method on a base station considering user-experienced quality (QoE) for each application. We aim at increasing users whose experienced quality is higher than a certain threshold, since users tend to dissatisfy and stop communication when QoE is lower than it. We conducted evaluations assuming that users were watching a video and browsing a Web page while they were moving. Evaluation shows that average QoE for Web improves by up to 1.48 point and the number of users whose QoE is more than 3.0 is 2.1 times more than conventional methods.

    There are two major challenges in video streaming through the best-effort networks such as the Internet and mobile networks. The first challenge is to improve the users' quality of experience (QoE). The communication throughput fluctuates widely on best-effort networks because of radio interferences and cross-traffic, which causes the video interruption and playout delay. The Second is the utilization efficiency of network resources, which is from a viewpoint of a network operator. The increase of video data size with the evolution of high-resolution video occupies a network resource for a long time and makes network resources seriously tight. Another problem is that the received video data in a playout buffer goes to waste of the network resources when the user stops watching the video in the middle. In this paper, the authors propose a video streaming technology that solves the above two problems by combining a rate control method and a pacing technique based on the communication throughput prediction. By referring to the stochastic diffusion of the future throughput, the rate control selects the maximum bitrate under the condition that the playout interruption is avoided. The authors demonstrate that the proposed method improves the QoE indicator recommended by ITU-T (real number from one to five) by an average of 0.75 compared with the conventional methods. Furthermore, the experience shows that the pacing function improves the duration of opening network resources. Although the playout buffer size of the proposed method increases by 2 〜 3 MB, it is a predicted need to maintain high QoE.

    Device-to-device1 (D2D) technology in fifth-generation wireless communication (5G) can leverage densely deployed multiple ad hoc networks. Much research has been done to improve QoS, such as throughput, which would decrease because of ad hoc networks' interference with each other. We focus here on the capture effect and its impact on the throughput performance. A contention window control method, ACWA, which improves the throughput of ad hoc networks by exploiting intentional collisions, has recently been proposed thanks to the capture effect. However, the unfairness of throughput between ACWA and the Distributed Coordination Function (DCF) might occur because ACWA could be too aggressive. We propose a modified ACWA method (GSAR scheme) that drastically improves the unfairness and keeps throughput as high as ACWA. GSAR just uses DCF at the sending node and uses ACWA in the rest nodes. In our evaluations considering capture effect, Jain's fairness index resulted in 1.0 from 0.56 in two ad hoc networks with DCF and GSAR.

    We set next research & development issues in this project. As core techniques, (1) collection of wireless communication records, (2) prediction of wireless communication quality based on the record history, and (3) delivery control and route navigation based on the quality prediction. As extension techniques, (4) large scale deployment, security, sensor assist, new wireless communication support, and QoE evalutions, and (5) prototype implementations. For (1) to (3), we proposed quality prediction methods using machine learning, adaptive delivery control maximizing QoE metrics, and moving route navigation maximizing communication quality such as throughputs. For (4) to (5), we tried cloud system extension, performance improvement by using additional sensors and implementation experiments over actual networks. Finally, we published our research contributions in international conferences and transactions with peer reviews.

    The purpose of this research project is by exploring context-aware, resource requirement-driven network densification to realize ultra-high capacity and massive access capability for next-generation wireless access networks. To this end, we have tackled on the resource management and inter-cell interference mitigation problems in heterogeneous wireless cellular networks, and proposed optimization algorithms for dynamic cell-range expansion, users' cell selection, and dynamic network clustering with base station sleeping and shared caching functions. We have also studied on online resource management algorithms for mobile edge computing to provide computing and data caching capabilities in wireless access networks. By leveraging reinforcement learning and fussy logic based techniques, we have also proposed low-overhead clustering based routing protocols for context-aware data delivering in vehicular networks utilizing multiple wireless access technologies.
