Predictive routing in a mobile ad hoc network
First Claim
1. A method for operating 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:
- predicting future-needed routes in the network, a route comprising a set of wireless communication links and mobile nodes from a source to a destination;
predicting future-network dynamics;
discovering at least partial routes along predicted future-needed routes in the network based upon the predicted future-network dynamics; and
storing the at least partial routes.

Abstract
The mobile ad hoc network includes a plurality of wireless mobile nodes and a plurality of wireless communication links connecting the nodes together. A method for managing and controlling the discovery and maintenance of routes in the network includes predicting future-needed routes or the need for future communications in the network, and predicting future-network dynamics or topology. Partial and complete routes are discovered along predicted future-needed routes based upon the predicted need for routes and the predicted network dynamics or topology. Route tables are built and updated at each mobile node with a route discovery process to store the partial and complete routes in the network.
