Abstract

Several gateway selection schemes have been proposed that select gateway nodes based on single QoS metric, for instance link availability, link capacity etc. or multiple non-QoS metrics, such as the combination of gateway node speed, residual energy, and number of hops, for Mobile Ad hoc NETworks (MANETs). Each scheme just focuses to improve only single network performance such as network throughput, packet delivery ratio, end-to-end delay or packet drop ratio. However, none of those schemes improves overall network performance. To improve the overall network performance, it is necessary to select a gateway with stable connection, maximum link capacity and less latency. In this paper, we propose a gateway selection scheme that considers multiple end-to-end QoS parameters such as route availability period, route capacity and route latency, to select a potential gateway node. The precise estimation and propagation of end-to-end QoS metrics are proposed in this paper. We simulate our gateway selection scheme with a simple hybrid gateway discovery algorithm and it shows that our gateway selection scheme improves throughput, packet delivery ratio with less energy consumption per node. Also it improves the end-toend delay compared to the single QoS gateway selection schemes.
