Energy efficient cluster management scheme for ubiquitous sensor networks

초록

The scheme proposed in this thesis organizes dynamically clusters at the time of events occurrence and maintains them. The other side, the existing cluster based USN(Ubiquitous Sensor Networks) organize at the network initial time in a lump. So the existing method causes of much energy exhaustion. Therefore the scheme proposed in this thesis can be more efficient than the existing one in the aspect of the energy usage and the gathering and sending data. In order to efficiently process various events, the scheme proposed in this thesis divides a cluster when the other events occurred in the area which the cluster organized in. In another case, it merges clusters when a same event occurs in a different near cluster. Like above, the scheme of this thesis dynamically organizes clusters in the node centeredness. The simulation to evaluating the scheme shows that the scheme of this thesis increase the performance by maximumly 50% compared with the existing study. © 2008 IEEE.
