A Cluster-Based Algorithm for Energy-Efficient Routing in Wireless Sensor Networks

Energy-efficient routing is a critical problem in multihop wireless networks due to the severe power constraint of wireless nodes, the research on routing algorithm is pivotal in the architecture of wireless sensor networks. This paper analyzes the implementation and existing issues in LEACH. Specifically for node energy and the network lifetime, it proposes an energy-efficient routing algorithm based on cycle-switching cluster head. It improves node energy efficiency, balances energy consumption of all sensor nodes, enhances reliability of data transmission and postpones network lifetime in comparison to LEACH. Simulation results showed that the algorithm is efficient. Moreover, the protocol increases the balance of energy dissipation, scalability and reliability of WSN.
