    摘要: Provided is a method of synchronizing time for a multihop sensor network. According to the method, receiving nodes accurately synchronize time by adding a delay transmission time value to a beacon frame in a beacon mode, or by using a time synchronization frame and time synchronization acknowledgement frame containing time information and superframe structure information in a non-beacon mode. Accordingly, a mesh topology is supported, and a media access control (MAC) structure having high reliability and low delay time is provided.

    摘要: Provided is a method and system for managing an identification (ID) of a widely moved sensor node. The method includes recognizing, at a gateway, a node to check an ID of the node, allocating an ID of the gateway as the ID of the node when the ID of the node checked by the gateway is null, sending the ID of the node to a management server when the ID of the node checked by the gateway is not null and is different from the ID of the gateway, and when a new ID is received from the management server, allocating the new ID as the ID of the node.
