Les réseaux de capteurs sans fil sont un type de réseau décentralisé et auto-configurant dans lequel les noeuds de capteurs peuvent détecter des informations et les transmettre à la station de base. En raison de la nature décentralisée et du déploiement lointain, la consommation d'énergie est le principal problème des réseaux de capteurs sans fil. Pour réduire la consommation d'énergie des capteurs sans fil, le regroupement hiérarchique est le type de technique de regroupement le plus efficace. Dans ce schéma, l'ensemble du réseau est divisé en grappes de taille fixe et des têtes de grappe sont sélectionnées dans chaque grappe. Les têtes de grappe sont sélectionnées sur la base de l'énergie et de la distance par rapport à la station de base. Le noeud de capteur qui se trouve à la plus faible distance de la station de base et qui dispose d'une énergie maximale est sélectionné comme chef de grappe. Dans ce travail de recherche, le protocole WEMER est mis en oeuvre et amélioré pour augmenter la durée de vie des réseaux de capteurs sans fil. Dans le protocole WEMER, l'ensemble du réseau est divisé en grappes et des têtes de grappes sont sélectionnées dans chaque grappe. Les noeuds leaders sont également sélectionnés dans le réseau et prennent les données des chefs de grappes et les transmettent à la station de base.
