PERFORMANCE EVALUATION OF GATEWAY DISCOVERY ROUTING PROTOCOLS IN MANETS

In this paper we had used modified Ad-hoc On Demand routing protocol(AODV) called AODV + to integrate MANET with Internet using a stationary gateway. The communication between the mobile nodes in MANET and fixed node in internet pass through the gateways. Gateway bridge up MANET and Internets. Due to the dynamic nature of MANET, the changes in topology are very frequent and the task of routing the data turn out to be a challenging. We had evaluated the performance of the key protocols AODV+ and Destination-Sequenced Distance Vector (DSDV) by simulating them in the wired cum wireless scenario and their performance has been compared on the basis of three performance metrics : packet delivery ratio, average end-to-end delay and average throughput.
