Abstract
A method and apparatus for internetworked communication between first and second wireless networks containing first and second pluralities of wireless nodes, respectively, is disclosed herein. In a preferred implementation a first dual-power node participates in both a first wireless network and an overlay network. The dual-power node is configured to transmit and receive in both a high-power mode and a low-power mode. The dual-power node operates in an overlay network and facilitates data transmission between low-power nodes and high-power nodes by toggling between these two power modes. In a preferred implementation, a third wireless network containing a third plurality of wireless nodes is utilized. The overlay network can accommodate a plurality of high-power or dual-power nodes.
