Claim:
1. A wireless communication node device, the node device comprising: a network adaptor configured to perform short-range wireless communication; a channel manager configured to receive channel setting information comprising information about channel member nodes, through the network adaptor, to store the received channel setting information, and to propagate the stored information via the network adaptor; a channel state manager configured to update a channel state table which indicates that the node device is connected to another node device, in response to the node device being connected to the other node device through the network adaptor, and to propagate the updated connection state table via the network adaptor; and an alarm controller configured to verify a connection state between the channel member nodes by analyzing the connection state table, and to generate an alarm control signal based on the verified connection state, wherein the alarm controller is configured to generate a control signal indicating an abnormal connection state between the channel member nodes when a node not connected with any of the other channel member nodes is present among the channel member nodes as a result of analyzing the connection state table.
