A Preliminary Study on Lifetime Maximization in Clustered Wireless Sensor Networks With Energy Harvesting Nodes

Free registration required

Executive Summary

Clustering is used extensively in wireless sensor networks to optimize lifetime. Within clustering, the optimization of Cluster Head (CH) location is critical since CHs consume energy faster and have greater influence on lifetime than Non-Cluster Head (NCH) sensors. Energy Harvesting Wireless Sensor Networks (EH-WSNs) use energy harvesting devices to harvest energy from environment. In contrast with the traditional battery powered wireless sensor networks, EH-WSNs have extended network lifetime substantially. In this paper, the authors present a single cluster algorithm for lifetime optimization in homogeneous wireless sensor networks with one solar powered sensor.
