Abstract: A self-organizing wireless network includes a plurality of nodes, each of which is configured to originate messages, be a destination of messages and relay messages. Each message is transmitted in a frame that includes the cost of conveying the message to the destination node for the message and also the cost so far expended in the conveying of the message. Each time the message frame is transmitted, either by the originating node or by a relaying node, the node ascertains whether the cost to convey the message from that node to the destination node is less than the conveying cost contained in the received frame. If it is, the node retransmits the frame after having incremented the incurred cost by the relay cost of that node and decremented the cost to convey by the same value. Otherwise the node discards the message.
