Performance Analysis According to the Change of Cluster Size in Large Scale Wireless Sensor Networks

Free registration required

Executive Summary

In large scale sensor networks, scalability and robustness are very important, and sensor nodes are also highly power constrained. Clustering, a method of grouping sensor nodes, can meet these requirements. Sensor networks also need to support fast delivery of important and urgent data. The purpose of this paper is to analyze the effects of cluster size on application's QoS, select proper cluster size based on the analysis, and suggest method to improve performance in clustering environment.
