ENERGY HARVESTING FROM NEIGHBORING NODES BY ROAMING DEVICES WITHIN A NETWORK

In a wireless communications network, a mobile node harvests energy from another node of the wireless communications network and stores energy, e.g., to re-charge a battery, thereby extending the amount of time between battery replacements or lifespan of the mobile node. Logic for registration and initiation of an energy harvesting session is included in a gateway node that is accessible to both the mobile node and another node that is configurable as a wireless charger node. The gateway node serves as a central intermediary that enables the mobile node to register once with the gateway node. The mobile node sends the request for the wireless charging session to the gateway node, as needed, and the gateway node assigns another node in the wireless communications network to serve as the wireless charger node based on the location of the mobile node.
