We developed an Ad hoc On-demand Multipath Distance Vector protocol with Path Preferential Selection Probabilities (AODVM-PPSP) for a mobile ad hoc network(MANET). This protocol introduces a new method, in which each node deliberately selects one of the multipath routes to utilize. It adapts preference for the route with the least transmission delay time and node throughput. We examined our protocol under various network loads. We evaluated our protocol with Omnet simulator and the performance is compared with the conventional methods. We found that the multiple routes were efficiently selected and there by resulted in higher packet delivery ratio and lower routing packets. The simulation results show that our proposed protocol has the significant improvement over others.
