A Routing Algorithm for Supporting Soft-QoS in Mobile Ad Hoc Networks

Recent work in mobile ad hoc network routing protocol development has demonstrated how global route discovery can be performed more efficiently by leveraging the known topology of each node´s local surrounding area. In this paper, we proposed a hybrid routing scheme based on a dynamic clustering algorithm. The adaptive clustering algorithm deals with mobility, transmit power conservation and improving system throughput. Routing algorithm proposed in this paper is decoupled from the clustering algorithm, it dynamically balance the tradeoff between proactive and reactive routing, while also dynamically tradeoff route optimality for routing overhead in a novel way. Moreover, this paper describes how to gather three metrics, which are used to support Qos aware route computation.
