A High Efficiency Wireless Broadcasting Retransmission Scheme Based on Network Coding

In order to improve the efficiency of the lst packets retransmission in wireless network,this paper presents a retransmission method with exclusive or network coding for the scence of one sending node and multiple receiving nodes.We use an optimization coding strategies to constitute the lost packages.Now,a retransmission can realize the effect which equal the traditional method of retransmission for a lot of times.Theoretical analysis and simulation experiments show that the method can reduce the retransmission number effectively,simple and feasible to realize.
