摘要:
Provided are a communication method and apparatus of a wireless sensor network which uses at least one channel and has a tree structure. The method includes: generating windows, where a beacon interval is divided, according to each channel; selecting a window, which is not assigned to nodes that exist within a predetermined range from a certain node, from among the generated windows; and the certain node communicating with a child node of the certain node by using a channel to which the selected window belongs during a time corresponding to the selected window.
