WIRELESS COMMUNICATION STATUS ACQUIRING METHOD AND RADIO STATION

WIPO Patent Application WO/2011/058925

A1

In a multihop wireless network, information about the communication environments of communication paths can be collected with the real time characteristic of data communication secured. In each of a plurality of stations, that is, relay stations and other radio stations, when a receiving unit receives a communication frame accommodating data, a local-station diagnosis information generating unit generates a local-station diagnosis information obtained by diagnosing the status of the communication environment of the local station. An other-station diagnosis information extracting unit extracts other-station diagnosis information from the received communication frame. A diagnosis information unifying unit unifies, based on accommodation format information, the local-station diagnosis information and the other-station diagnosis information and accommodates the unified diagnosis information into the communication frame. In this way, information about the statuses of the communication environments of the radio stations existing on communication paths can be collected, which allows the statuses of the communication paths to be diagnosed.
