DATA TRANSFER PATH CONSTRUCTION METHOD, WIRELESS COMMUNICATION NETWORK SYSTEM AND SENSOR NETWORK SYSTEM

摘要

PPROBLEM TO BE SOLVED: To provide a data transfer path construction method for autonomously establishing a data transfer path from each device to a base station, using a miniaturized apparatus such as a sensor to which low power consumption is required, and also to provide a wireless communication network system, and a sensor network system. PSOLUTION: A base station 0 transmits a detecting signal 55 to wireless devices 51-54, the wireless devices 51 and 52 that receive the detecting signal transmit detection response signals 56 and 57 each containing an identifier specifying the presence device as both a response signal and a detecting signal of other wireless device, and the base station 0 that receives the detection response signals recognizes the wireless devices 51, 52 of transmission sources as wireless devices belonging to the present station. Wireless devices 53, 54 that receive the detection response signals 56, 57 from the wireless devices 51, 52, belong to the wireless devices 51, 52 of the transmission sources and transmit detection response signals 58, 59, and the wireless devices 51, 52 transmit link notification signals 60, 61 representing identifiers of the wireless devices 53, 54 as transmission sources of the detection response signals 58, 59, to the base station 0.
