“…In a normal scenario interference will increase with an increase in the number of D2D pairs with a fixed number of RBGs in a cell and it will reduce the interference with the increasing number of RBG. These two scenarios are analyzed and compared with an existing work [10] where the resource exchange only in a D2D environment was considered. The resource exchange was purely based on the preference matrix of the UEs.…”

Scarcity in communication spectrum in cellular network is one of the major challenges faced by the service providers around the world. Many efforts were put forth to manage the efficient spectrum distribution among various cells in the network. Reusing the resources by different cells in a safe distance without interference is the current mechanism to improve spectrum efficiency. Spectrum efficiency can be even improved by reusing the resources within a single cell. Device to Device (D2D) communication, a new technology boosts the spectrum reuse inside a cell in 5G. The major hurdle in implementing D2D is in the management of interference in a highly mobile environment. This high mobility risks the life-time of a D2D link and frequent shifting from D2D mode to normal cellular mode will occur. In this paper an effort is put forward to maintain the D2D link as long as possible through a resource exchange mechanism. The exchange occurs when interference by a cellular or D2D link threatens another D2D link. This approach can improve the life-time of a D2D link and thereby improving the consistency of the network.

“…Money exchange, resource exchange, and reputation exchange are three widely used incentive mechanism [23][24][25]. However, these three incentive mechanisms need to assume that UAV can obtain UEs' complete information such as channel conditions, resource requirements, and costs for caching, which is unrealistic for practical implements.…”

Edge caching is a promising technology to alleviate the burden on backhaul and improve the quality of experience (QoE) of users in unmanned aerial vehicle (UAV)-enabled mobile edge networks, which has played an important role in wireless communication systems. However, owing to the selfish nature and limited battery life of the user equipments (UEs), only a limited part of the caching resources will be shared by the UEs. To drive the UEs to share more caching resources to improve the social welfare of the UAV-enabled mobile edge network, in this paper, we jointly design an edge caching strategy and reward contract optimization scheme. Aiming to maximize the utility of the UAV, a joint edge caching and contract optimization problem is formulated. Firstly, a novel edge caching strategy is proposed based on the content popularity. Then, an optimal reward contract is designed by reducing the restrictions. Finally, the system performance of the designed caching strategy and reward contract is evaluated compared with two benchmark caching schemes with no incentives. Simulation results show that the proposed scheme performs better than the other two schemes in terms of the utilities of the UAV and UEs, which proves the efficiency of our proposed scheme.

“…For this purpose device-to-device (D2D) communication system is one of the promising technologies introduced [6][7][8][9][10]. D2D communication is a 5G cellular communication standard that facilitates nearby active devices to communicate directly without going through a base-station (BS) [11][12][13][14][15]. Services such as multimedia sharing, online gaming and cloud computing etc., have become vital part of daily communications.…”

In this paper, we investigate the outage probability, channel capacity and symbol error rate (SER) performance of device-to-device (D2D) communication systems. The D2D communication system is affected by several co-channel interferers. Gamma fading channel is considered for the D2D communication system. The channel for the co-channel interference is assumed to be Nakagami faded. An expression for the probability density function (PDF) of the signal-to-interference ratio (SIR) is presented. The PDF is a function of distances between various devices in the D2D system, path-loss, channel fading conditions and signal powers. Based on the PDF expression, we present the expressions for the outage, channel capacity and SER. With the help of numerical results the performance of D2D communication system is discussed under various conditions of interference, path-loss and channel fading.
