METHOD AND SYSTEM FOR ASSIGNING RADIO CHANNEL ON MESH- LIKE WIRELESS NETWORK

摘要

PROBLEM TO BE SOLVED: To assign a radio channel to each of radio links without conflict on a wireless network, with which a plurality of wireless nodes are distributively located and each of wireless nodes establishes the radio link with each of a plurality of nearby wireless nodes. SOLUTION: This method is provided with a step for classifying the respective wireless nodes on the network to a high-order node or low-order node, step for classifying the respective high-order nodes to a plurality of groups, a step for setting the updating order of radio channels to be assigned to the radio link thereof by each of high-order node for the unit of a group within the updating period of radio channels to be repeated in a prescribed cycle, and a step for setting the radio channel to be assigned to each of radio links between the high-order node in each of groups and each of adjacent low-order nodes according to the updating order without competition with registered radio channels.
