Energy Efficient Constant Cluster Node Scheduling Protocol for Wireless Sensor Networks

The Wireless Sensor Network (WSN) consisting of a large number of sensors are effective for gathering data in a variety of environments. In this paper, the authors first completely analyzes the basic distributed clustering routing protocol LEACH (Low Energy Adaptive Clustering Hierarchy), then proposed a new routing protocol and data aggregation method in which the sensor nodes form the constant cluster and the cluster-head elected based on the residual energy of the individual node calculation with constant clustering and the node scheduling scheme is adopted in each cluster of the WSNs. In the node scheduling scheme (ACTIVE and SLEEP mode) the energy efficiency is increased near to 50% than LEACH protocol and lifetime of the networks also increased.
