METHOD FOR COLLECTING LOW POWER SENSOR DATA OF WIRELESS NETWORK USING PERIODIC PREAMBLE SENSING

摘要

The present invention relates to a method for collecting low power sensor data of wireless network using PPS which variably sets a value of PPSI (periodic preamble sensing interval) for an elastic preamble sensing during a PPS (periodic preamble sensing) mode setting process in a wireless network, to increase the value of PPSI when the transmission and receiving of data between one coordinator (repeater) and multiple devices (collector) is intermittent, and reduce the value of PPSI when the transmission and receiving of data is frequent, thereby reducing the power consumption of the wireless network.
