A Multi-constraint QoS Routing Protocol with Route-Request Selection Based on Mobile Predicting in MANET
2007
Due to the dynamic nature of the network topology and restricted resources, the stable routing based on quality of service (QoS) in mobile ad hoc network (MANET) is a challenging task. QoS requirement with uncertain parameters has become a very important research issue in MANET. The paper presents a multi-constraint QoS routing protocol with route-request selection based on mobile predicting (QRRSMP). The QRRSMP is the scalable routing algorithm whose control overhead should be under control to keep up with increasing offered load. In this algorithm, the goal is to construct a stable QoS routing path and reduce the number of route-request (RREQ) packet by forwarding or discarding RREQ packets. Simulation results show that the proposed approach reduces the control overhead and provides the QoS routing stability in dynamic mobile networks.
