Improving QoS Performance in the Gateway Node

Various gateway selection schemes have been proposed to select gateway node based on single QOS and multiple non-Qos path parameters. The single QOS parameter includes path availability period, link capacity and end to end delay. Similarly multiple non-Qos parameters consist of gateway node speed, residual energy and number of hop for MANET. The entire above mentioned scheme will improve only a single network performance such as network throughput, packet delivery ratio, end to end delay or packet drop ratio but none of these schemes improves the overall performance. So to improve the overall network performance it is necessary to select a gateway with stable path.
