CONTROL METHOD FOR WIRELESS COMMUNICATION SYSTEM, AND THE WIRELESS COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To extend a communicable range in a wireless communication system comprising a plurality of node stations which perform multi-hop communication.

SOLUTION: Respective node stations 200 perform RSSI (radio signal strength indicator) tests with another node station 200 and stores the result of the RSSI tests in respective node stations 200 in a node station 200A (control station) which is one of the node stations 200. The node station 200A groups another node station 200B into a plurality of groups, on the basis of the result of the RSSI tests; detects a first node station 200B which can communicate directly with the node station 200A for each group; detects a second node station 200B which cannot directly communicate with the control station but can communicate with it indirectly via the first node station 200B (S651 to S654); and generates a routing table, where the node station 200A and the first or the second node station 200B communicate on the basis of the result of detection (S655).
