Mobile Ad hoc Networks (MANETs) is a type of wireless ad-hoc network which is a self-arranging network of mobile nodes connected by wireless route links which creates an discretionary topology. The mobile nodes are free to move randomly and to arrange themselves in a random manner. Thus, the wireless ad hoc network topology may expand rapidly and unpredictably. In mobile adhoc networks, the routing protocol plays an important role for improving Quality of Service(QoS). There are many different types of routing protocols such as reactive, proactive and hybrid. The Dynamic Source Routing (DSR) is a reactive routing protocol which establishes routes on-demand, as they are needed. In this paper, we proposed a new routing protocol Modified Dynamic Source Routing (M-DSR) which is based on route caching strategy and a better route caching method can decrease routing overheads with the help of the existing route information more competently which intern gives good performance than the existing DSR routing protocol with respect to set of performance metric such as packet delivery ratio, throughput, packet loss and overhead, under different pause time. We design proposed M-DSR routing protocol and implemented with certain simulation parameters using Network Simulator (NS-2) tool. The performance analysis of routing protocol designed for wireless networks has been very challenging. Hence, simulations are always utilized to obtain the desired performance results.
