Multi-channel mobile ad hoc network
First Claim
1. A method for operating a mobile ad hoc network comprising a plurality of wireless mobile nodes and a plurality of wireless communication links connecting the plurality of nodes together over a plurality of different wireless channels, the method comprising:
- at a source node, sending a route request over each of the plurality of channels to discover routing to a destination node;
at each intermediate node, determining whether the intermediate node can support the route requested and, if so, forwarding the route request to other intermediate nodes and the destination node over each of the plurality of channels;
at the destination node, upon receiving the route request, generating a reply to the source node for each discovered route;
at the source node, selecting a route to the destination node on at least one of the plurality of channels; and
at the source node, sending a transmission to the destination node along the selected route.

Abstract
A mobile ad hoc network includes a plurality of wireless mobile nodes and a plurality of wireless communication links connecting the plurality of nodes together over a plurality of channels. The method includes sending a route request over each of the plurality of channels to discover routing to a destination node, and selecting a route to the destination node on at least one of the plurality of channels. The route request may be sent over each of the plurality of channels sequentially, and the route request preferably includes a source node channel identifier.
