Abstract
The objective of our work is to propose a new approach called ES-WSN (Energy Efficiency by Switching between roles in WSNs) for the efficient use of energy in wireless sensor networks (WSN). Our solution ES-WSN extends the lifetime of the nodes in the network and guarantees a fair evolution of their level of energy. This is based on the exchanging of roles between relays and sensors nodes based on their positioning and deployment in the WSN. This process is provided according to two parameters from the communication environment. The first one is the distance between the sensors and relays nodes. The second one is the remaining energy of nodes in the network. After evaluation, ES-WSN has achieved better performance compared to two other solutions proposed in the literature.
