Advanced Dynamic Source Routing with QoS Guarantee

Abstract—With a great deal of different applications increasing, it needs to provide effect communication for mobile Ad Hoc network. In this paper, we present an advanced dynamic source routing (ADSR) algorithm for such network. ADSR can select routes according to link state and dynamic delay detection. In the route discovery phase, ADSR finds paths with the greatest link stability factor. In the route maintenance phase, it effectively keeps monitoring network topology changes by delay prediction and timely performs rerouting before the paths become unavailable. With such enhancement strategies, ADSR can significantly improve the overall performance of network. Experimental results show that ADSR can achieve higher packet delivery rate and at the same time retain lower end-to-end delay comparing with conventional DSR algorithm.
