OPTIMIZED RELIABLE AND LOAD BALANCED ROUTING PROTOCOL FOR MOBILE AD HOC NETWORKS

In Dynamic Source Routing (DSR) protocol for mobile ad hoc networks (MANETs), high transmission overhead is involved since DSR header size comprises the IP addresses of all the nodes involved in the transmission of the data packet. By reducing the amount of the packets involved in routing, the DSR control overhead is reduced by most of the optimization techniques. In this paper, we develop an optimization technique for DSR to reduce the overhead during data transmission. The optimization is performed in two phases. In the first phase, the route for the data packet transmission is determined and the bloom filter is used for the estimation of the compressed source route at every node. In the second phase, before the transmission of the data packet, the related information of the transmitting intermediate node is deleted. This prevents the data packet from including all its intermediate node information on transmission, in turn maintaining the data packet size to the original size without overloading it. Thus this technique reduces the overall overhead in the network. By simulation results, we show that the proposed technique reduces the overhead and hence the energy consumption and delay
