Abstract:

To make network coding based multipath routing(NCMR)reliability transmission mechanism more practiced, local retransmission and network coding based multipath routing(LR-NCMR) reliability transmission mechanism was proposed for wireless Ad hoc network, transmitting coded packets over multipath and using retransmission within local area. Comparing with NCMR, the simulation shows that LR-NCMR is more reliable than NCMR and it can reduce the redundancy in the network.

Key words: wireless Ad hoc network, reliability transmission, random network coding, redundancy, local retransmission
