Traditional network coding can reduce forwarding times of data packets

but brings larger delay and network congestions.In this paper

a Partial Network Coding based Real-time Multicast (PNCRM) protocol is proposed for supporting real-time multicast services in Mobile Ad-hoc Networks (MANET) .This protocol combines the partial network coding with the establishment of mesh together.It can not only reduce the end-to-end delay effectively

but also improve the final throughput performance.Simulation results show that

in a wide range of scenarios with varying number of receivers and mobility

PNCRM works much better than PUMA or traditional network coding based real-time multicast protocols in terms of packet delivery ratio and end-to-end delay.
