Optimizing The Performance Of DSR Routing Protocol For MANET’s Determining The Most Significant Factor Using Taguchi Approach

MANETs are infrastructure-less networks formed by dynamic nodes through wireless medium. Routing in MANETs is a challenging issue. Dynamic Source Routing Protocol (DSR), a reactive routing protocol is adaptable for the mobile nature in wireless medium. In enhancing the throughput of the network using the DSR routing protocol for MANETs Taguchi approach is used. A series of experiments were conducted in Opnet simulator 14.5 for improving the performance of DSR Routing protocol. A set of factors like Broadcast Jitter, Network Size ( number of nodes) and Simulation time considered in recognizing the most significant elements by designing a series of experiments with Taguchi Approach. A L18 Orthogonal-array(OA) with a mixed-level design for the characters at different levels, were analysed by taguchi approach to an optimum level. The experimental solutions reveals that broadcast jitter is as the most influential element in enhancing the throughput of the network using the DSR protocol in the wireless medium.
