Patent ID: 8180353

Claim:
A routing method for a mobile ad-hoc network including a plurality of mobile nodes, comprising: (a) setting, at each current node, a self-potential value to a destination node upon receiving a route recovery request; and (b) transmitting, when a transmission packet is destined to the destination node, the packet through a route established with at least one node in a descending order of potential value; wherein the self-potential value is set with reference to potential values of neighbor nodes, and wherein setting the self-potential value comprises: (i) checking the potential values of the neighbor nodes; (ii) relaying, when all the neighbor nodes' potential values are greater than the self-potential value, the route recovery request to the neighbor nodes; and (iii) resetting the self-potential value on the basis of the neighbor nodes' potential values contained in the route recovery responses received from the neighbor nodes, the neighbor nodes' potential values being updated in response to the route recovery request.
