DYNAMIC GTS ALLOCATION METHOD FOR WIRELESS CONTROL NETWORK USING IEEE 802.15.4

摘要

PURPOSE: A dynamic GTS allocation method for a wireless control network based on IEEE 802.15.4 is provided to increase a network use rate and the number of supportable nodes in each GTS in a single PAN environment, thereby satisfying a predetermined condition to apply an IEEE 802.15.4 wireless communication technique to an industrial field bus. CONSTITUTION: A dynamic GTS allocation method for a wireless control network based on IEEE 802.15.4 comprises the following steps. A coordinator node reads profile information of an I/O device. An update condition of a GTS assignment table is calculated. A GTS assignment table is generated based on the I/O device profile information read by the coordinator node. It is determined whether the I/O device profile information read by the coordinator node is changed. The GTS assignment table is updated according to the determination result and the calculation result.
