Abstract: A WSN has multiple sensor nodes, a bi-directional gateway sensor node, and a server. The WSN also includes circuitry configured to process a route request message from an origination sensor node to a destination sensor node. A message packet of each of the sensor nodes includes a minimum energy field, a minimum energy harvesting rate field, and a sum of energy field. The circuitry is also configured to determine a new delivery route based upon comparing a minimum energy and a minimum energy harvesting rate of an instant sensor node with a minimum energy and a minimum energy harvesting rate contained in the message packet, and select a lower minimum energy and a lower minimum energy harvesting rate from the instant sensor node or the message packet. The circuitry is also configured to broadcast the lower minimum energy and the lower minimum energy harvesting rate throughout the WSN.
