NCRM: A Network Coding Based on Real-time Multicast Protocol in Mobile Ad-Hoc Networks

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 requirements of real-time services,NCRM also adopts a mechanism of strict delay constraints.Simulation results show that,in those scenarios with many receivers or high motilities,NCRM is significantly better than those traditional protocols such as PUMA and MAODV in terms of transmission reliability and energy consumption.
