Abstract:
1. A method for routing message data from a source node to a destination node in a mobile ad hoc network comprising a plurality of intermediate mobile nodes between the source node and the destination node, and a plurality of wireless communication links connecting the nodes together, the method comprising: at the source node, transmitting a route request to discover routing to the destination node; at each intermediate node, determining whether the intermediate node can support the route request and, if so, forwarding the route request to one of other intermediate nodes and the destination node, and temporarily reserving node resources for supportable route requests; at the destination node, upon receiving the route request, generating a reply to the source node for each discovered route; at the source node, ranking the discovered routes according to at least one link metric; at the source node, selecting a plurality of routes to the destination node based upon the ranking; at the source node, transmitting route confirmations to intermediate nodes on the plurality of selected routes; and at the source node, distributing the message data to the destination node along the plurality of discovered routes.
