Relay power control for two-way (TW) full-duplex (FD) relay network is studied in this letter. In the prior literature, the relay is assumed to always use its full transmit power in a TW FD relay network. However, high transmit power will increase loopback self-interference at the relay node and thus make the incoming link to the relay become the bottleneck for the end-to-end performance. Therefore,...
The deployment of small cell base stations (SCBSs) overlaid on existing macro cellular networks can potentially improve the coverage and capacity of cellular wireless systems. However, a massive deployment of SCBSs also leads to an undesirable increase in energy consumption and severe intratier and inter-tier interference. In this paper, the joint design of discontinuous transmission (DTX) and power...
Device-to-Device (D2D) technology provides a potential way to improve cellular network throughputs. However, severe interference is introduced with universal frequency reuse, which significantly degrades the network performance. In this paper, we investigate distributed power control strategies in a D2D underlaid cellular network. An enhanced single-leader-multiple-followers Stackelberg game model...
Power conservation is an issue of primary concern in wireless sensor networks. Since the nodes deployed have limited battery power higher transmit powers would lead to an earlier end of the nodes/network lifetime. The network deployed has to have a good connectivity level to ensure uniformity through out the network and avoid the circumstances leading to a very early lifetime end of some of the nodes...
Network coding is seen as a promising technique to improve network throughput. In this paper, network coding in cooperative relay networks and user cooperative networks is investigated and an optimized power allocation scheme is provided. By comparing with traditional relay forwarding in a simple two-user scenario, network coding shows a better system performance with a lower hardware cost and higher...
