Description
Summary:To improve the transmission efficiency of wireless network, a broadcasting retransmission algorithm based on network coding technology is put forward in this paper. In accordance with the packet loss distribution probability characteristic, it generates the new retransmission sequences, and it uses the multiple nodes network coding method to combine the lost packages to realize retransmission. Through the mathematics analysis and simulation, it can be proved that the algorithm can ensure decoding the receiving information flows. Meanwhile the retransmission can achieve the local optimality. Compared with the traditional retransmission method, this algorithm can effectively reduce the average number of packages transmission.
