Performance Simulation of Routing Protocols in Ad Hoc Wireless Network

In ad hoc mobile networks (MANET), the mobility of the modes is a complicated factor that significantly affects the effectiveness and performance of ad hoc routing protocols. Mobility and traffic patterns for each node such as intermediate and end nodes are restrained to extract features of each routing protocol. In this paper, we focus on the performance of the routing protocols for stationary end nodes in ad hoc networks using a network simulator (NS-2). Our simulation results explore following four performance features. Firstly, the high speed degrades in terms of AODV RREQ sending packets merely on the density of 10 nodes per 100 square meters. Secondly the high speed exceeding 15 m/s creates more RREP sending packets over dense node conditions. Thirdly, the number of DSR RREQ to send packets increases by 40% compared to that of AODV. Finally, the DSDV protocol shows the inefficiency in terms of the node speed and the dense node condition.
