Performance evaluation of network coding-aware neighbor based topology control protocols in MANETs

Much attention has been paid to reduce the redundancy of broadcasting in MANETs. Since broadcasting produces many redundant packets, it will create a broadcast storm problem. Recently, many researchers are using network coding to reduce the number of transmissions in wireless networks. In this paper, we apply network coding technology into neighbor based topology control protocols to further reduce the number of transmissions. We evaluated the performance of the network coding based protocols. Our simulation results show the energy gain of the network coding-aware neighbor based topology control protocols. We also evaluated the impact of coding delays involved in network coding.
