QoS Routing Protocol Based on Link Stability with Dynamic Delay Prediction in MANET

Mobile ad hoc network (MANET) is a multi-hop temporary autonomous system of mobile nodes with wireless transmitters and receivers without the aid of pre-established network infrastructure. With the development of network and demand of users, QoS has become one of the focus issues. A new routing protocol is proposed in this paper, which can provide QoS guarantee. In the route discovery phase, it finds paths meeting delay requirement with great link stability factor. In the route maintenance phase, it effectively keeps monitoring network topology changes through delay prediction and performs rerouting in time. Simulation results show that it can meet with the delay requirement while decrease the routing cost.
