A QoS Routing Protocol Based on Path Stability in Mobile Ad Hoc Network

With the prevalence of multimedia application, it has become a research focus to provide QoS in ad hoc mobile network However, current QoS routing protocols concentrate on finding a feasible path that satisfies QoS conditions and overlook path stability According to the features of ad hoc network, a QoS routing protocol PSQRP is proposed which is based on path stability The protocol selects a route in term of path stability and reduces the probability of link breakage It increases the request success ratio by using the technology of primary and secondary reservation The simulation results show that the protocol gains good performance in dynamic network environment
