Abstract
It is significant to develop a method to realize efficient broadcast retransmission in wireless networks. Network coding is a promising technique for this purpose. In this paper, we propose a novel Wireless Broadcast Retransmission scheme based on Opportunistic Network Coding (WBRONC) aiming at reducing the number of transmissions, as well as improving the transmission efficiency. This scheme employs a new packet scheduling algorithm which uses Packet Distribution Matrix (PDM) directly to select coded packets. Thus, low computational complexity is obtained by it. It is denoted from the analysis and simulation results that the WBRONC scheme provides a substantial improvement both in transmission efficiency and computational overhead.
