A remote mobile node interconnection is achieved via a peer-level multihopping technique. Many routing protocols have been designed for Ad Hoc Networks. However, these kinds of protocols are not able to react fast enough to maintain routing. In the paper, we propose a new protocol to improve AODV. We overheard the main route through neighbors near main route. Our proposed protocol will try to repair the main route when link/node failed. However, when link is broken in data transmission process, the route path will be repaired through neighbors near the main route. Simulation results show that we can reduce overhead dramatically. Another, we propose a method about selecting reliable main route. We try to improve the selecting methods. We estimated the Link Broken Probability (Pe) of the routing path. We selected a reliable main route through the Pe value. Simulation results show that we can select a more reliable main route.
