Abstract

To further improve the multi-relay cooperative transmission efficiency in wireless networks, this paper proposed a dynamic programming scheduling based on network coding with less feedback(DPNC-LF). The DPNC-LF considered the effective information of each relay and the transmission reliability of each link, and implemented the multi-relay cooperative forwarding to improve transmission effectiveness with the minimum number of retransmissions. In the condition of each link independent mutually and the state transition path selected adaptively, the DPNC-LF determined the optimal forwarding node for the entire transmission process. The simulation results show that the algorithm is more effective than random selection scheduling in average throughput and reducing the number of retransmission. With the feedback information dependence reduced and the feedback overhead decreased, the performance of the scheme is close to the performance of greedy algorithm scheduling.
