METHOD OF CREATING, CONTROLLING, AND MAINTAINING A WIRELESS COMMUNICATION MESH OF PICONETS |
摘要 |
A method of controlling and sharing access to a wireless network wherein some stations of the network may be out of range of other stations of the network. The method includes the steps of: first, each station periodically transmits a beacon containing a bit map having a bit location for every station on the network and monitoring the beacons of stations within its range; second, in response to a beacon being no longer detected, each station transmits a bit map containing an indication of only the stations that it can still receive; third, on receiving a bit map with not all stations indicated, each station responds by adding stations that it can receive to the received bit map and transmitting the updated bit map; fourth, each station repeats the third step until the updated bit map indicates that all stations are still in the network or that a station is missing from the network; and finally, if a station is indicated to be missing from the network, each station updates the bit map. Through the application of these steps, the invention controls access to the network without a global master. The present invention has the advantage of controlling a network without the need for a central master station, and does not require continuous global knowledge of the topology of the network. |
