Multi-Path QoS Routing Algorithm Based on Disjoint Nodes for Mobile Ad Hoc Networks
Yang Tao, Ya Wang · Applied Mechanics and Materials · 2014
. To meet the needs of voice, video and other large multimedia data transmission services, a new multi-path routing protocol, which is named MP-QAODV, with QoS guarantees for MANET was proposed. The Routing method based on disjoint nodes and backup multiple paths was used in the protocol. Through introducing two weights constraints based on single-source and single-path network model, a non-deterministic optimal constraints algorithm was proposed. After introducing and instantiating the path stability factor and the path length factor, mathematical model of their relationship was built. The mathematical model was used to improve AODV protocol and the improved protocol has QoS guarantee. Simulation results showed that MP-QAODV is better than AODV, AOMDV in the aspects such as average end to end delay, packet delivery ratio and route control overhead. The experiment demonstrated the effectiveness of MP-QAODV protocol.
