Abstract—Energy conservation is a key issue in Wireless Sensor Networks based systems design. Clustering based routing protocols have been developed in orderto reduce network traffic to the BS and thus to extend the network lifetime. A clustering variantis LEACH which is one of the most prominent hierarchical routing protocols used in wireless sensor networks(WSN). Maximizing the network lifetime is one of the major challenges. Maximizing a sensor network lifetime is equivalent to minimizing the different energy sources. In fact, a sensor node consumes energy to accomplish.In fact, a sensor node consumes energy to accomplishhis roles in the networkwhich are mainly processing and transmission of a set of physical quantity on the environment around it. This paper proposes a hierarchical routing protocol based on LEACH but the difference lies in the mode of clusters formation and clusters heads selection (CH) ensuring balance between energy consumption sensors. Simulations show that the proposed protocol extends the life of the network compared to LEACH and iMod-leach.
