METHOD FOR SELECTING CHANNEL BETWEEN PORTABLE DEVICES AND SMART-WATCH IN ZIGBEE

摘要

The present invention relates to a method for selecting a channel for communication between a small device and a smart watch which are connected through a zigbee network. The method is based on a super-frame structure and comprises the steps of: selecting a channel with the lowest energy as a candidate channel by detecting energy of channels except at least a use channel before occurrence of interference between the selected use channel and another wireless communication channel; and selecting the candidate channel as a new use channel when the interference between the selected use channel and another wireless communication channel has been occurred.
