AMDR: A Reinforcement Adaptive Mean Delay Routing Algorithm for MANET

In the few last years, there is an increasing need of QoS guaranties for multimedia applications in mobile ad hoc networks. Therefore, routing protocols designed for mobile ad hoc networks must be adapted to support such needs. While several QoS routing protocols were proposed, adaptive routing has not be enough exploited. We focus in this paper on delay oriented adaptive routing in mobile ad hoc networks. Our solution does not assume that network is synchronized. We integrate a mean delay estimation model at each node in our protocol. Adaptive mean delay routing (AMDR) protocol proposed in this paper uses two kinds of exploration packets having the task of gathering delay information of available paths and updating probabilistic routing tables. To reduce the overhead of our approach we introduce the use of a new MPR mechanism based on delay.
