Cooperative relay selection strategy design, as one of the fundamental issues in cooperative communication, has attracted dramatic attention in recent years. However, many of the previous works have been done under the assumption that the transceiver nodes were fixed. In this paper, we address the robust relay selection problem that the active transceiver nodes are dynamic. First we use “capacity gain” as the metric for relay selection strategies and formally define the robust relay selection problem. Then we propose arobust relay selection scheme called RRS which aims to maximize the transmission capacity gain in the worst case. Finally, our simulations have shown the RRS scheme can improve about 50% minimum capacity gain than the random select algorithm.
