A multipath QoS routing algorithm based on entropy in ad hoc networks

As the Ad Hoc network topology constantly changing, it often leads to routing reconstruction. In order to reduce the route reconstruction, the paper presents a node-disjoint multi-path QoS routing algorithm based on entropy in ad hoc network. The algorithm adopts the entropy metric to measure the routing stability and satisfies the bandwidth constraint. Therefore, it can obtain the node-disjoint multipath QoS routing. Simulation results show that the algorithm can reduce average latency and improve the success rate of data transmission.
