In conventional opportunistic relay selection schemes, one or multiple relays with better channel condition are selected. However, if frame aggregation is supported for improving MAC throughput, each relay can have different amounts of data and thus conventional selection schemes may choose a worse relay node only with good channel condition but little data. In this paper, we propose a novel opportunistic relay selection scheme when frame aggregation is adopted. In the proposed scheme, a relay node is selected in a distributed manner by considering the amount of data as well as channel condition, and therefore the most appropriate relay node can be chosen. Simulation results demonstrate that the proposed scheme outperforms other relay selection schemes, especially when the number of relay nodes is large.
