Design on Multipath Routing in Ad Hoc Network Based on Load-balance

Based on the analysis of Ad hoc On-demand Multipath Distance Vector routing (AOMDV) protocol and discusses its route discovery process.According to the deficiency of the lacking congestion control and load balance mechanism,this paper proposes AOMDV_D protocol as a result of improving the AOMDV,this protocol can establish an appropriate main path by adding congestion control and load balance.Simulation results show that the AOMDV_D protocol has lower average delay and higher packet delivery ratio comparing with AOMDV protocol in same network environment.
