PNCRM: A Novel Real-time Multicast Scheme in MANETs Based on Partial Network Coding

To reduce delay and network congestions caused by traditional network coding techniques, in this paper, we propose a Partial Network Coding based Real-time Multicast (PNCRM) scheme for supporting real-time multicast services in Mobile Ad-hoc Networks. This scheme combines the idea of partial network coding with the meshbased real-time multicast scheme together. It can not only reduce the end-to-end delay effectively, but also improves the final throughput performance significantly. Simulation results show that the PNCRM outperforms the PUMA and existing network coding based real-time multicast schemes in terms of packet delivery ratio and end-to-end delay.
