“…To fully exploit the benefits of data and computation offloading, mobile traffic and computational works can also cooperate in D2D networks. Specifically, mobile devices in close proximity can be connected via WiFi Direct [16], Bluetooth, etc., in a D2D manner for data and task cooperation between users. This is referred to as D2D data and computation offloading.…”

Device-to-device (D2D) communication is becoming an increasingly important technology in future networks with the climbing demand for local services. For instance, resource sharing in the D2D network features ubiquitous availability, flexibility, low latency and low cost. However, these features also bring along challenges when building a satisfactory resource sharing system in the D2D network. Specifically, user mobility is one of the top concerns for designing a cooperative D2D computational resource sharing system since mutual communication may not be stably available due to user mobility. A previous endeavour has demonstrated and proven how connectivity can be incorporated into cooperative task scheduling among users in the D2D network to effectively lower average task execution time. There are doubts about whether this type of task scheduling scheme, though effective, presents fairness among users. In other words, it can be unfair for users who contribute many computational resources while receiving little when in need. In this paper, we propose a novel blockchain-based credit system that can be incorporated into the connectivity-aware task scheduling scheme to enforce fairness among users in the D2D network. Users' computational task cooperation will be recorded on the public blockchain ledger in the system as transactions, and each user's credit balance can be easily accessible from the ledger. A supernode at the base station is responsible for scheduling cooperative computational tasks based on user mobility and user credit balance. We investigated the performance of the credit system, and simulation results showed that with a minor sacrifice of average task execution time, the level of fairness can obtain a major enhancement.

“…Based on which kinds of frequency bands (namely, licensed bands and unlicensed bands) have been used for D2D transmission in past studies, D2D transmission can be divided into the following four categories: (1) D2D transmission using only licensed bands (such as that described in [11][12][13][14][15][16][17][18][19][20][21][22][23][24]); (2) D2D transmission using only unlicensed bands (such as that described in [11,[24][25][26][27][28][29][30][31]); (3) D2D transmission using either licensed or unlicensed bands in a selective manner (such as that described in [32,33]); and (4) D2D transmission using both the licensed and unlicensed bands simultaneously (such as that described in [34]). Regarding the first two categories, Asadi et al [11] presented a D2D communication survey and overview showing that the traffic loads and transmission delays encountered by BSs can be effectively ameliorated by D2D connections, with such connections simultaneously having the effects of increased system throughput and improved energy usage efficiency (which result, in turn, in reductions in the total amount of power expended by a network).…”

“…For example, Asadi and Mancuso [25] published research in which a protocol focusing on the topic of implementation was proposed, while Golrezaei et al [26] proposed the use of localized D2D transmissions as one means by which the throughput of video files transmitted via cellular communication systems could potentially be increased. A year earlier, in 2013, a study utilizing a device-focused methodology to investigate the development, design, and experimental evaluation of a delay-bounded energy-conscious bandwidth allocation scheme for heterogeneous wireless networks was published by Dimitriou et al [27].…”

Abstract:To date, the amount of research conducted regarding the subject of energy-efficient transmission in device-to-device (D2D)-assisted cellular network systems simultaneously utilizing both licensed and unlicensed bands is lacking. This topic is of substantial relevance to emerging 5th-generation (5G) cellular network systems, so the present study was conducted in order to address it in a practical manner. Specifically, this study proposes a simple yet effective algorithm aimed at ensuring efficient energy usage when such network systems make transmissions while utilizing both licensed and unlicensed bands. Based on novel system configurations with respect to bandwidth and link mode configurations, the proposed D2D-assisted transmission algorithm was designed with a system-level perspective in mind in order to yield greater efficiency in terms of transmission mode selection and link mode selection. As a result of these features, the proposed algorithm can not only maintain acceptable rates of transmission for all the connected users, but can also enhance system performance by a significant degree in terms of both energy efficiency and connection efficiency. Moreover, the results of simulations conducted to test the algorithm indicate that it is not only feasible, but, given its simple yet effective design, also easy to implement, such that it can serve as a valuable reference for the operators of 5G networks.

“…In the case of stable channel condition, the disadvantage of this method is to make the CH on work for a long time, then the CH's charge will be consumed faster than the CNMs, this will lead the result of short clusters lifetime. Furthermore, the work in [26] elaborates on the required modification of LTE and WiFi technologies and defines a protocol stack to connect both of them. This paper sheds light on the different aspects of integrating LTE and WiFi such as channel quality feedback, scheduling and security.…”

A large number of new data consuming applications are emerging in the daily routines of mobile users. Device-to-Device (D2D) communication as a new paradigm is introduced to reduce the increasing traffic and offload it to the user equipment (UE). With the development of UE multi-radio interface, we first develop a new hybrid architecture concept for D2D communication. The architecture combines ISM 2.4G spectrum as the Out-Band mode using Bluetooth and Wifi-Direct with the cellular spectrum as the In-Band mode. Secondly, we design a scheme that forms the Out-Band cluster and makes the following periodic signaling interaction via the Bluetooth interface. Traffic is transferred via the Wifi-Direct interface inside the cluster but carried on the cellular spectrum among the clusters.Simulation results show that our proposal increases the system throughput, saves power consumption and prolongs the clusters lifetime.
