A cooperative retransmission strategy for error-prone wireless networks

In this paper, an error-prone cooperative retransmission strategy (E-CRS) is proposed for wireless networks. In E-CRS, when a receiver can not receive a frame correctly, the retransmission is performed by a cooperative node that overhears the packet successfully, rather than by original source. The throughput of the proposed scheme is analyzed and evaluated in error-prone and no collision channel. The simulation results show that our proposed cooperative retransmission strategy can increase significantly the throughput, compared with the original retransmission scheme.
