Abstract: Wireless sensor network (WSN) is consists of a large number of low-cost sensor nodes through wireless communication. Sensor nodes collect environmental information and transmit it to the base station (BS). The sensor nodes are usually; resource constrained and battery limited. Therefore, Energy conservation of the sensor nodes are the important issues considered in the design of Wireless sensor networks. So; designing of an energy efficient routing protocol can maximize the network lifetime. Multi-hop Low Energy Adaptive Cluster Head (M-LEACH) is energy efficient routing approach which improves the life time of the network. However, this routing technique has shown limitation in increasing life time of the network. This paper presents an improved multi-hop LEACH (IM_LEACH) routing protocol for cluster-based networks. The proposed protocol improves Multi Hop LEACH protocol based on energy efficient cluster head (CH) selection technique. The simulation results explain an Improved Multi-hop LEACH (IM_LEACH) routing protocol for cluster-based networks. The proposed protocol achieves. The simulation results illustrate the energy efficiency of the multi-hop cluster-based routing approach. The proposed method attains significant enhancement in term of network lifetime and provides improved energy performance for wireless sensor networks.
