Performance enhancement of ad hoc networks with adaptive monitor based routing

To effectively support the communication in such a dynamic networking environment as the ad hoc networks, the routing protocol has to be adaptable to the spatial and temporal changes in the characteristics of the network, such as traffic and mobility patterns. In this paper, we propose and analyze a routing protocol called Adaptive Monitor Based Routing (AMBR) that discovers and maintains routes in hierarchical and distributed fashion and locally repairs the broken link. The main motivation behind the proposed AMBR is to drastically cut down flooding, to substantially tame the routing overhead, to repair broken link locally in order to minimize the routing overhead and to increase efficiencies in packet movement in the ad hoc networks. An analytical model for the AMBR technique is presented. Simulation results illustrate its performance and demonstrate its good behavior comparing with other prevalent protocols. The proposed protocol achieved substantial improvement in terms of flooding, routing overhead and network overhead and hence, provides enhanced reliability.
