Abstract:
A method for managing and controlling the discovery and maintenance of routes in a mobile ad hoc network comprising a plurality of mobile nodes and a plurality of wireless communication links connecting the mobile nodes together, the method comprising:transmitting beacon signals from each mobile node; determining a node condition at each mobile node; varying the beacon signals based upon the determined node condition; building and updating route tables at each mobile node with a first one of proactive and reactive route discovery processes to define routes in the network, a route comprising a set of wireless communication links and mobile nodes from a source to a destination; receiving the beacon signals and storing node condition information at each node; predicting route stability over time based upon the node condition information; and switching to a second one of the proactive and reactive route discovery processes when predicted route stability reaches a first transition parameter.
