Abstract :
In this paper, the detect scheme based on equal gain combining (EGC) at the destination node is first investigated for a cooperative wireless sensor network with decode-and-forward (DF) relaying protocol. It is shown by simulation that the EGC scheme is a good practical solution by comparing with the traditional maximal-ratio combining (MRC) scheme and the cooperative-MRC scheme. Then the combination of EGC at physical and automatic repeat request (ARQ) at data link layer is analyzed further, and a practical cross-layer design scheme based on EGC and truncated ARQ is finally presented.
