Comparison of Performance for on-Demand Routing Protocols in case of MANET with the help of NS2

Mobile ad hoc network (MANET) is a dynamic and self organized network, which is a collection of wireless mobile nodes (hosts) communicating with each other without any predefined infrastructure or centralized administration. Because of mobility of nodes there is no fixed topology and it may result to frequent link breakage. The primary goal of any ad-hoc network routing protocol is to meet the challenges of the dynamically changing topology and establish an efficient route between any two nodes with minimum routing overhead and bandwidth consumption. So an efficient protocol is required to find route between source and destination node. A several protocols have been introduced for improving the routing mechanism to find route between any source and destination host across the network. This paper analyses and compares the performance of AODV and DSR routing protocols in terms of packet size, number of traffic sources, mobility rate, topological area, number of nodes. Keywords— DSR, AODV, Routing Protocol, MANET, NS2.
