A Multiple QoS Constraints Routing Protocol Based on mobile Predicting in Ad Hoc Network

In mobile ad hoc network (MANET), multiple QoS (Quality of Service) routing is the process for establishing the path which is from the source to the destination with multiple QoS constraints. Multiple QoS constraints is one in which the delay, delay jitter, bandwidth and cost should satisfied the pre- specified bounds. The paper discusses the QoS routing problem with multiple QoS constraints, deals with the delay, delay jitter, bandwidth and cost metrics. It presents a multiple QoS constraints routing protocol with mobile predicting (MQRPMP).The MQRPMP attempts to reduce the overhead for reconstructing a routing path with multiple QoS constraints by mobile predicting. In this paper, the proof of correctness of MQRPMP is also given. The simulation results show that the MQRPMP approach provides an accurate and efficient method of estimating and evaluating the QoS routing stability in dynamic mobile networks.
