Research on QoS Routing Algorithm in ad hoc networks

Due to the dynamic nature of the network topology and restricted resources, quality of service (QoS) and stability routing in mobile ad hoc network (MANET) is a challenging task. This paper presents fuzzy controllers based QoS routing algorithm (FQRA). The performance of this scheduler is studied using NS2 and evaluated in terms of quantitative metrics such as path success ratio, average end-to-end delay and throughput. The simulation results shows that the FQRA approach provide an accurate and efficient method of estimating and evaluating the route stability in dynamic mobile networks.
