I-NDMR Protocol in Mobile Ad Hoc Network

To release the confliction and jam of Node-Disjoint Multipath Routing (NDMR) protocol, an improved Improved NDMR (I-NDMR) protocol is proposed. This protocol reduces the shared links betwen multiple sources and destinations, chooses the path with lowest load to send data packets Load Information is recorded in RREP packet to evaluate transmission load and LOAD_UPDATE packet is broadcast periodically. Although the transmission path and the amount of control message may increase a little, the packet delay and network traffic can be released efficiently. Simulation results show that the I-NDMR can effectively enhance the performance of network.
