METHOD FOR RECONSTRUCTING TREE WIRELESS SENSOR NETWORK

摘要

According to the present invention, a method for reconstructing a wireless sensor network tree comprises the steps of: (a) with respect to a plurality of sensor nodes, respectively granting roles of a club head and a club member, and establishing a wireless sensor network in a hyper tree structure; (b) selecting a first node and a second node which constitute the wireless sensor network in the hyper tree structure and are in a parent-child relationship; (c) if the roles of the first node and the second node are alternated, determining whether a length of a link constituting the wireless sensor network is shortened; (d) repeatedly performing the step (b) and (c) and selecting a switching target parent node and a switching target child node which allow the length of the link to be most shortened; and (e) alternating the roles of the switching target parent node and the switching target child node and reconstructing the wireless sensor network.
