Comparative Performance Analysis of Two Ad-hoc Routing Protocols
Priti Garg, Asma Tuteja · 2011
A Mobile Ad-Hoc network is a decentralized wireless network. The network is ad-hoc because it does not rely on a pre-existing infrastructure, such as routers in wired networks or access points in managed (infrastructure) wireless networks. Mobile Ad hoc networking (MANET) is becoming increasingly important in today's world and a number of protocols have been developed. However, a comparison between them is lacking to help determine an optimal one. This study addresses this issue by comparing the relative performance of Ad hoc routing protocols; we compared on-demand and hybrid protocol; temporally ordered routing algorithm (TORA) and Dynamic Source Routing (DSR). This subjected the protocols to identical loads and environmental conditions and evaluates their relative performance with respect to quantitative metrics; throughput, average delay, packet delivery ratio and routing load. From the detailed simulation results and analysis of presented, we use NS-2 simulator for simulation of DSR and TORA protocol and variation occurs in mobility of packets, time interval between the packets sent and packet size of packets sent in throughout the protocols.
