Research and realization of multi-channel multi-interface wireless network coding based on guesswork

COPE, presented by Katti et al. (Proc. ACM SIGCOMM 2006, pp. 243-254), exploits the broadcast nature of the wireless medium through opportunistic network coding. In this paper, we introduce the basic knowledge and characteristic of COPE, and propose a multi-channel multiinterface wireless network coding algorithm based on guesswork (GUESS-MCMI-COPE). By reducing the space of reception reports and implementing multi-channel multiinterface, GUESS-MCMI-COPE can increase network throughput. We evaluate our design on NS2, and discuss the results. The results show that the performance of GUESSMCMI-COPE is superior to that of COPE.
