Abstract:
1. A method for generating an identification in a wireless sensor network, the method comprising: temporarily generating an identification of a first layer node by the first layer node; transmitting the identification of the first layer node to a second layer node; detecting whether the identification of the first layer node is duplicated, using the second layer node; transmitting a determination message from the second layer node to the first layer node when the second layer node detects that the identification of the first layer node is not duplicated; and determining the identification of the first layer node as a determined identification by the first layer node upon receiving the determination message; wherein the first and second layer nodes are in a hierarchical relationship such that the first layer node is a subordinate of the second layer node, wherein the identification of the first layer node is registered in an access node, and wherein the identification of the first layer node includes a node type and a serial number of the first layer node and a node type and a serial number of the second layer node which is an upper node of the first layer node.
