Clustering Technology for Mobile Sink Using Max Entropy Model*

Because the wireless sensor network uses proactive, if an event was occurred, the source node transmits immediately the detected data before sink node require. At this time the source node transmits the data to the nodes that are no need to receive, and so it is not efficient at the side of the energy efficiency. To solve these week points, in our paper, I made the cluster using max entropy of source node and mobile sink node. The proposed method considering the data movement direction on the basis and other features. The routing of the mobility of the sink, makes it possible for the source node to transmit safely the date to the sink node with the minimum energy consumption. The proposed method caused the energy reduction effect of the average 12.74% at 20km/h and the average 11.53% at 40km/h in [12] at the time of the data transmission. And also through the cluster that is considering the remained amount of energy of entire nodes and the distance to the sink node, it proved the fact that is possible to use the longer entire network communication time than that of Ref.[12].
