Abstract:
1. A method for generating an identification in a wireless sensor network, the method comprising: temporarily generating an identification of a relay node and transmitting the identification of the relay node to a access node by the relay node; determining the identification of the relay node as a relay node determination identification by the relay node, when a first determination message that the identification of the relay node is not duplicated among identifications managed by the access node is received from the access node; temporarily generating an identification of a sensor node and transmitting the identification of the sensor node to the relay node by the sensor node; determining the identification of the sensor node as a sensor node determination identification which comprises information on the relay node determination identification by the sensor node, when a second determination message that the identification of the sensor node is not duplicated among identifications managed by the relay node is received from the relay node; wherein the sensor node, relay node and the access node forms a tree-shape hierarchical structure, the access node is located on an upper layer than the relay node and the relay node is located on an upper layer than the sensor node.
