The routing protocol plays an important role in the ad hoc network. A recent trend in ad hoc network routing is the reactive on-demand philosophy where routes are established only when required. Most of the protocols fall in this category. However, these kinds of protocols are not able to react fast enough to maintain routing. In this paper, we propose a new protocol to improve existing on-demand routing protocols by creating a mesh and multiple backup routes. When the network topology changes, our algorithm would establish backup routes dynamically. We also examine the performance by simulating our protocol using NS2. The experimental results show that our proposed protocol has less control packages, lower routing packet overhead and high receive ratio compared with others.
