چکیده
Energy-efficient routing is a critical problem in multihop WSN due to the severe power consumption of wireless nodes, the research on routing algorithm is pivotal in the architecture of WSN. This paper analyzes the implementation and existing issues in LEACH. Specifically for node energy and the network lifetime, it proposes an energyefficient 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 increase 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.
