Claim Text:
1. A network management method of an area-limited self-organized wireless network, wherein, only nodes located in a limited area may communicate with each other, the nodes in the self-organized wireless network including a master node or at least one sub node, and there is only one master node in the same limited area, the network management method comprising: a step of, when a communications apparatus which is entering the limited area receives area limiting signals used for indicating a specific area in which network nodes are located, determining by the communications apparatus whether the master node exists in the limited area; a step of, if it is determined that the master node exists, carrying out identity authentication with regard to the master node based on the area limiting signals and letting the communications apparatus be a sub node by the communications apparatus; and a step of, if it is determined that the master node does not exist, letting the communications apparatus be the master node by the communications apparatus, wherein, the master node is in charge of entering of a new sub node and synchronization of shared secret keys between the network nodes, wherein when there are plural master nodes in the network, any one of the plural master nodes sends its priority indicating a priority level of being a master node to other master nodes, and if a master node finds that there is another master node whose priority is higher than that of the master node, then the master node automatically becomes a sub node.
