Improved Dynamic Source Routing Algorithm in Mobile Ad hoc Networks

With the popularization of real time multimedia services, how to provide quality of service (QoS) support has become a hot point of mobile Ad hoc network (MANET) researches. However, the established path is often disconnected because of the mobility of nodes and dynamic topology. In this paper, an improved dynamic source routing protocol is proposed. This routing protocol tries to find a stable path between source and destination, and supervise the state of path by real time link detection to reduce the probability of communication discontinuity and provide QoS support by soft path switching.
