Improving the quality of service based on route stability in MANETs Using Dynamic Source routing protocol

Abstract

A Mobile Ad hoc Network (MANET) is a collection of nodes or mobile devices that communicate with each other without any centralized administrator. When a route is broken in an on-demand routing protocol, route recovery and maintenance procedures are initiated and it will consume more bandwidth and the delay will be high. To improve the performance of DSR a simple stability model is used. The stability of the route is analyzed by the received signal strength. The received signal strength from a node is higher than the threshold value the signal strength value will be stored in the neighbor information table. Using this information source select the path with high stability value and thus reduce the path break in intermediate nodes. Simulation results show improved performance in the throughput and reduce the packet loss, delay.
