BPDSR:MANET Bi-directional Routing Model Based on Chord algorithm

To improve the inquiring efficiency of MANET route, this paper expanded Chord algorithm into DSR and presented a routing model BPDSR through the study of P2P and MANET. By bi-directional routing algorithm and shared routing algorithm, BPDSR lowered the inquiring complexity and eliminated the invalidity of route and detour problem. Put the new protocol into simulation in NS-2 and compared its performance with DSR, The results show that the inquiring efficiency of BPDSR is better.
