Abstract

A method for node communication in a mobile ad hoc network, which network includes a plurality of wireless mobile nodes and a plurality of wireless communication links connecting the nodes together, includes the steps of transmitting node condition information from a given mobile node using a signal; determining a node condition of the given mobile node, where the node condition includes priority of information to be transmitted by the given mobile node; and varying the signal by changing a transmission characteristic based upon changes in priority of information to be transmitted by the given mobile node.
