Broadcasting Efficient Opportunistic Network Coding for Multisource-Multidestination Scenarios

摘要：

Network coding across multicast transmission can significantly reduce the number of retransmissions for wireless broadcasting. However, most of the existing network coding schemes for these scenarios base on the assumption that each source has priori knowledge of the others, which restricts the application of network coding seriously. In this paper, we propose a multi-relay opportunistic network coding (MR-OPP-NC) scheme for multisource-multidestination (MSMD) broadcasting scenarios without the above mentioned assumption. In specific, a joint network coding and opportunistic selected scheme is designed in decode-and-forward strategy. Simulation results show that the MR-OPP-NC scheme proposed outperforms the pure opportunistic relaying scheme in delay performance.
