In ad hoc networks, information transfer is achieved in multihop mode using peer-to-peer routing. A route consisting of multihops breaks primarily because of the failure of single or adjacent links, caused by relative movement of one or more nodes. To address this inherent characteristic of ad hoc networks, we propose and analyze an on-the-fly strategy that locally repairs the broken route, thereby minimizing the routing overhead. The main motivation behind our Localized Route Repair (LRR) work is to decrease the reaction time of routing protocols, which totally avoids retransmissions. A detailed simulation with MAC layer and physical layer model is used to understand the impact of this mechanism on the performance of routing protocol. An analytical model for the LRR technique is also presented and the results observed to match well with the simulation results. Our technique clearly achieves substantial improvement in terms of communication delay, routing overhead, and, hence, provides enhanced reliability.
