LCHREP: Layer and Cluster based Hierarchical Routing and Energy Optimization Protocol in Wireless Sensor Networks-

 In this work, we propose a new hierarchical routing protocol called LCHREP (Layer and Cluster based Hierarchical Routing and Energy Optimization Protocol) that aims to minimizing energy consumption for wireless sensors network. LCHREP uses clusters formed on a layers and also uses multihop between these different layers. Results of simulations indicate that the proposed protocol allows better remaining energy after clusters heads selection, less amount of energy consumed in terms of sending packets. It allows also to reduce the number of nodes failed, and therefore to keep more nodes alive after sending packets.
