Real-Time Multicast With Network Coding In Mobile Ad-Hoc Networks

Abstract In this paper, a Network Coding based Real-time Multicast (NCRM) protocol is proposed for real-time multicast services in Mobile Ad-hoc Networks (MANET). Through reducing the forwarding times for data packets in MANET, NCRM can not only decrease the energy consumption but also improve the throughput performance. To satisfy the maximum end-to-end delay deadline requirements for real-time services, NCRM adopts a mechanism with strict delay constraints. Simulation results show that, in those real-time multicast scenarios with many receivers and/or high node motilities, NCRM outperforms those traditional protocols such as PUMA and MAODV in terms of transmission reliability and energy consumption significantly.
