A relay selection mechanism using RED factors for cooperative communications in mobile ad-hoc networks

Abstract

Cooperative communication uses other communication devices to relay transmission. Relay selection plays a vital in improving the performance of cooperative communication. Some works have been done on relay selection in cooperative communications. This research proposes a new practice for selecting the optimal relay in cooperative communication. The proposed work considers RSSI, residual energy and the distance factors i.e., the “suitability” score is based on the above three measures, which can be used to determine the relay node. Since when the potential relay say x is closer to the destination, the channel quality between them is better, moreover fewer collisions would occur as there are less number of potential relays closer to the destination than x and selecting the node with sufficient residual energy as relay would withstand throughout the duration of retransmission.
