Abstract: Recently large numbers of applications are developed in wireless sensor networks with more numbers of portable sensor nodes to increase the quality of service of such applications. The failure occurred in sensor nodes typically affects the quality of service of WSNs.This algorithm is a combination of discrete round trip delay & round trip path algorithm and genetic algorithm. The combination of these algorithms are used to preventing traffic in networks and also provides better performance improvement, less delay and less packet loss rate. The simulations are done in network simulator 2 and results shows that this method provides better performance compared with existing systems.

Keywords: QoS, Round trip path, Round trip delay, genetic, chromosome.
