Reactive and Proactive Routing Protocols Performance Metric Comparison in Mobile Ad Hoc Networks NS 2

Abstract: Wireless networks use some sort of radio frequencies in air to transmit and receive data instead of using some physical cables. The most admiring fact in these networks is that it eliminates the need for laying out expensive cables and maintenance costs. When we are setting up a wireless network at home or in the office, there are many features available to you with the network installation. From sharing information directly to connecting to the same Internet source, wireless networks may using multiple computers in the same location far easier than having each computer run individually. The purpose of this paper is to study, understand, analyze and performance comparison between two mobile ad-hoc routing protocols DSDV and AODV where the first one is a proactive protocol and other one is a reactive protocol. DSDV is best suited for only smaller networks and AODV is suited for large-scale mesh networks.The performance of the AODV is better than the performance of the DSDV routing protocol. A network simulator- called MobiREAL simulator has been designed and developed for performance evaluation of AODV and DSDV routing protocol in this paper. To compare the performance of AODV and DSDV routing protocol, the simulation results were analyzed by graphical manner and trace file based on Quality of Service metrics: such as throughput, PDR and delay. In this paper we simulate performance with different node such as ,60,805,15,30,40 and 100 and different mobility speed such as smsm /,35/25 and sm/50 .
