Enhancing multihop routing protocols in wireless sensor networks using LEACH-1R

Energy consumption is one of the most important factors in wireless sensors networks (WSN). In fact, many protocols have been modified to enhance the lifetime of deployed sensors networks. In our work, we are investigating multihop clustering protocols such as MR-LEACH and MH-LEACH as well as their modified version that integrate the LEACH-1R protocol that which aids to stabilize the network at the phase of clustering. Experimental results shows a clear advantage when LEACH-1R was integrated in both MR-LEACH and MH-LEACH in term of energy consumption, life time, and stability of the network when compared to their original version.
