Patent ID: 7430194

Claim:
A method for communication between coordinator-based wireless networks connected together through a backbone network, the method comprising: acquiring a physical address of a destination network device belonging to a first coordinator-based wireless network; generating a frame containing the physical address of the destination network device; and transmitting the frame to a connecting device connecting a second coordinator-based wireless network containing a source network device with the backbone network, wherein the acquiring of the physical address of the destination network device comprises: transmitting a physical address request frame requesting the physical address of the destination network device; receiving a physical address response frame containing the physical address of the destination network device from the connecting device in response to the physical address request frame; and extracting the physical address of the destination network device from the physical address response frame, wherein at least the first coordinator-based wireless network is a network in which a randomly selected device within the first coordinator-based wireless network acts as a coordinator that assigns channel time to other devices within the first coordinator-based wireless network for data transmission.
