Abstract-This paper proposes an interference-limited relay assignment scheme for multi-hop wireless networks that exploits cooperative diversity to cope with problems of wireless channels and to enhance data transmission reliability. By combining the selection and incremental relaying schemes and by taking into account the channel status information and queue length at each node, the cooperative scheme improves the packet dropped ratio and end-to-end delay due to retransmissions. The proposed method is based on local channel measurement and requires no topology information. In addition, this paper also investigates the interference problem produced by the relay nodes and the failure probability of the best relay selection. Extensive simulations conducted to evaluate the performance of the proposed scheme indicate that it effectively enhances the network performance in terms of the packet delivery ratio, energy consumption, and overall packet delay.
