ABSTRACT:
In a centralized radio network consisting of several devices one device acts as master or network coordinator and has a transmission range. Basically, other devices of the network are able to adopt the role of a coordinator. This ability is used to enlarge the area of the network to a size larger than the transmission range of the master. A device asks its parent PNC to become a child PNC when a newly turned on device acts as a temporary PNC and broadcasts an initiation beacon indicating that it looks for a child PNC. The child PNC reports that it is available. The new device determines one of the available child PNCs to be its new master. The acknowledgment for the selected child PNC may be broadcasted to inform all the devices in the transmission range of the new device. The new device quits the role of the temporary PNC and associates to the existing network.
