Energy Efficient Hierarchical Cluster-Based Routing for Wireless Sensor Networks

In this paper we propose an energy efficient routing algorithm based on hierarchical clustering in wireless sensor networks (WSNs). This algorithm decreases the energy consumption of nodes and helps to increase the lifetime of sensor networks. To achieve this goal, this research network is divided into 4 segments that lead to uniform energy consumption among sensor nodes. We also propose a multi-step clustering method to send and receive data from nodes to the base station. The simulation results show that our algorithm is better than existing algorithms in terms of saving energy, balancing energy dissipation and prolonging network lifetime.
