Abstract

A method of communication between a plurality of network devices and an external electronic device is provided. The method includes receiving, at a first network device, device information and power information from a second network device, where the received device information and power information is transferred over a first communication link on a first network, where the first communication link is formed between a first transceiver of the first network device and a first transceiver of the second network device. The method further includes comparing the received power information with power information of the first network device. The method further includes transferring a portion of the received device information from the first network device over a second communication link on a second network when it is determined based on the comparison that the first network device is better suited than the second network device to communicate on the second network.
