Abstract:
Wireless sensor networks (WSNs) are composed of many low cost, low power devices with sensing, local processing and wireless communication capabilities. The major limitation of wireless sensor network is energy and network lifetime. In this paper, the cluster routing protocol LEACH (Low-Energy Adaptive Clustering Hierarchy) is considered and enhanced. This paper proposes a clustering routing protocol named Enhanced LEACH, which extends LEACH protocol by selecting a cluster head according to the minimum distance to the base station, which plays an important role in reducing power consumption in cluster head nodes and in the overall network. The simulation results show that Enhanced LEACH outperforms LEACH in terms of network lifetime and power consumption minimization.
