Efficient Clustering using Concentric Rings and Rectangular Region Formations in Wireless Sensor Networks

摘要

Sensor node deployment is vital in cluster formation. It is sensitive for a large area of sensor field. Hence there is a need to divide sensor field into small regions and then form clusters. Regions are characterized by area of sensor network, number of sensor nodes and fair distribution of nodes within each region. This paper focuses on two types of sensor field region formations, namely, concentric rings and rectangular region formation. Concentric rings region formation is based on the distance from sink which is at the center of sensor field. Rectangular regions are formed by continuously partitioning sensor field into equal parts. Both formations are evaluated for energy consumption and network lifetime for various transmission ranges. Results for energy consumption and network lifetime are compared. The results depict that clustering within rectangular region is better than concentric rings.
