Abstract
A wireless communication network includes mobile devices which may act as sources, targets, and intermediaries for transmitted information. An intermediate nodes that receives a signal from a source intended for a target may forward the signal in the direction of the target, if the target's location is known, or transmit the signal in a direction away from the sender of the signal, e.g., the source or another intermediate node. Upon receiving the signal, the target may transmit its address and current location more aggressively in the direction of the sender, e.g., the source, if the source's location is known, or in the direction of the intermediate node from which the signal was received. The nodes may determine the locations of other nodes in the network by extracting location information from the signal or from periodically updated global location reports transmitted by a master node.
