Abstract

Abstract:

Recently, cooperative communication has been regarded as one of the most promising techniques, which can achieve the spatial diversity with one antenna. In cooperative communication, the energy efficiency could be improved with the fixed transmission power. The relay node has a significant effect on the performance of cooperation. Therefore, how to allocate relay nodes becomes an important issue which should be addressed. However, existing work just focuses on the advantage cooperation gain, with the adverse effect ignored. Moreover, the advantage cooperation gain might not cover the adverse effect. To this end, we propose a Distributed Relay Node Assignment Method (DRNAM), considering both advantage and adverse effects caused by cooperation. Based on simulation results, the DRNAM can improve the energy efficiency significantly.

Key words: cooperative communication, relay node selection, diversity gain, additional interference
