In a device-to-device (D2D) communication underlaying cellular network, user equipments are required to operate cooperatively and unselfishly to transmit data as relays. However, most users behave in a more or less selfish way, which makes user selfishness a key factor that affects the performance of the whole communication system. We focus on the impact of node selfishness on D2D communications....
We consider downlink transmission in multi-cell wireless networks where in each cell one base station is serving multiple mobile terminals. There is no a priori channel state information (CSI) available at base stations and mobile terminals. We propose a low-complexity pilot-assisted opportunistic user scheduling (PAOUS) scheme. The proposed scheme operates in four subsequent phases: channel training;...
Future device to device communication using the LTE system bring new opportunities for application development. In the case of wireless sensor networks, unmanned aerial vehicles with LTE capabilities could be used to increase the network lifetime, while ensuring high transfer rates between LTE capable sensor nodes and the aerial vehicles. In this article we propose a hybrid heuristic algorithm able...
