Continuous advancement in wireless communication has enabled the deployment of wireless sensor networks for environment monitoring. The use of wireless sensor networks in this type of monitoring, it is very much difficult to replace the battery of the sensor node or replace whole sensor node once they deployed. So that development the different methodology to extend the lifetime of the sensor node is must. Low Energy Adaptive Clustering Hierarchy (LEACH) is cluster based routing protocol which provides life expectancy. In this paper proposed new routing protocols Energy-efficient Hybrid LEACH (EH-LEACH) in which the threshold criteria for selection of cluster head is changed and also consider residual energy of the sensor node.
