An Efficient Cluster Construction Strategy for Wireless Sensor Networks

Wireless sensor networks consist of small battery powered devices with limited energy resources. The energy efficiency is key design that needs to be enhanced in order to improve the life-time of the network. However, the conventional cluster constructions are difficult to control the geographical area of a cluster. The methods usually generate long-distance intra-cluster routing and can not keep the energy efficiency. This paper presents an efficient cluster construction strategy that can handle the geographical area of a cluster. Accordingly, the numbers of sensor nodes of clusters are balanced and long-distance intra-cluster data delivery can be avoided.
