Optimal Energy-Based Clustering with GPS-Enabled Sensor Nodes
Kowsar Ali, Sarmistha Neogy, Pradip Kumar Das · 2010
Wireless Sensor Networks (WSN) consist of a collection of wireless nodes that dynamically create a network themselves. However while doing so, not always energy optimization is considered. But energy consumption should be made as much low as possible since power is a constraint for these nodes. This paper proposes a clustering algorithm in Wireless Sensor Network that uses few GPS-enabled nodes or beacons that help in localization of the nodes and thereby orienting themselves within clusters such that energy consumption becomes optimum during their activities of sensing and communication. The paper focuses on optimizing energy consumption during cluster formation in sensor networks.
