Abstract
In this paper, we propose a relay selection strategy for randomly distributed multiple relays. A single relay is selected for transmitting signal from a fixed source to a fixed destination which requires minimum total transmit power. The lack of perfect channel state information (CSI) at the relay-destination link has been taken into consideration while selecting the relay. We consider the relay movement with low mobility features and evaluate the performance based on the total transmission power requirement. In addition, relay selection region is obtained to improve the overall performance of the system. Simulation results show that a similar performance in terms of total transmit power can be achieved at lower complexity if we select the relay from a specific relay selection region as compared to considering all the relays in the network.
