Abstract :
In this paper, we deal with a relay selection issue to improve throughput performance under signaling overhead and delay constrained system. The proposed relay selection protocol, which is based on analytic hierarchy process (AHP), adopts signal-to- noise ratio (SNR), system delay, and switching weight as selection criteria. We examined target system performance under various weighting to the above attributes. Also, average throughput can be maximized adaptively in various system environments. The proposed protocol entirely realizes the feature of opportunistic relaying (OR) protocol by totally weighting the SNR criterion. The performance of our protocol is verified in terms of average throughput, average delay and average relay switching counts.
