Quality of Service Analysis in Mobile Ad Hoc Network for TORA Protocol

A wireless Ad-hoc network consists of wireless nodes communicating without the need for a centralized administration, in which all nodes potentially contribute to the routing process. In this paper, we report the simulation results of four different scenarios for wireless ad hoc networks having thirty nodes. The performances of proposed networks are evaluated in terms of number of hops per route, delay and throughput with the help of OPNET simulator. Channel speed 1 Mbps and simulation time 600 sim-seconds were taken for all scenarios. For the above analysis TORA routing protocols has been used. The throughput obtained from the above analysis (four scenarios) are compared as shown in Figs. 3. The average media access delay at node_22 for two routes and at node_20 for four different scenario are compared as shown in Figures. 4 and 5. It is observed that the throughput will degrade when it will follow different hops for same source to destination (i.e. it has dropped from 1.65Mbps to 1.52 Mbps which is around 10.9%, and then dropped to 0.68Mbps which is around 35%).
