Mobile Ad hoc network is self-organizing and adaptive in nature. The nodes are mobile and forming a dynamic temporary network without any use of existing network. The routing in mobile ad hoc network is a difficult task because nodes are dynamic. A routing protocol is used to find routes between mobile nodes to facilitate communication within the network. Route should be discovered and maintained with a minimum of overhead and bandwidth consumption. There are number of routing protocols were proposed for Mobile ad-hoc networks. In this paper analysis of performance evaluation of three different routing protocols i.e. Ad-hoc on demand distance vector routing protocol (AODV), Dynamic Source Routing Protocol (DSR) and Destination-Sequenced Distance Vector (DSDV), which gives good performance for different parameters scenarios. And also highlights simulation based performance analysis of routing protocols on various metrics like overhead, end-to-end delay, Packet Delivery Fraction (PDF) etc by increasing the size of Network with variation in Pause Time for the same number of nodes. Network size and pause time affects the performance of selected protocols. DSDV gives good performance for small network size, but for large network size AODV performances good. End-to-end delay varies, but overhead and PDF is stable for all scenarios. Network Simulator (NS2) is used for this simulation work.
