An Energy Balanced Algorithm of LEACH Protocol in WSN


Chunyao Fu, Zhifang Jiang, Wei Wei and Ang Wei

In wireless sensor networks (WSNs), due to the limitation of nodes energy, energy efficiency is an important factor should be considered when the protocols are designing. As a typical representative of hierarchical routing protocols, LEACH Protocol plays an important role. In response to the uneven energy distribution that is caused by the randomness of cluster heads forming , this paper proposes a new improved algorithm of LEACH protocol (LEACH-TLCH) which is intended to balance the energy consumption of the entire network and extend the life of the network . The new algorithm is emulated by Matlab simulation platform, the simulation results indicate that both energy efficiency and the lifetime of the network are better than that of LEACH Protocol.

Keywords: LEACH Protocol; Energy consumption; Network lifetime; Matlab simulation
