Z-MSP: Zonal-Max Stable Protocol for Wireless Sensor Networks
Résumé
Clustering is a well-known energy enhancement approach used to prolong the lifetime of Wireless Sensor Networks (WSNs). However, it introduces another issue, which is the selection of the optimum number of clusters along with the appropriate cluster heads. In this paper, we study in detail the clustering approach and its impact on enhancing WSN lifetime. We provide a mathematical study that discusses the impact of clustering, where the WSN is divided into multiple zones, each zone functioning as an independent cluster. The WSN topology consists of 10 zones, all similar in area and density but differing in their distances to the base station. To prolong the WSN’s lifetime, we developed Z-MSP, an extension of MSP for Zonal WSNs. It maintains the highest stable period of MSP for the Z-WSN. Z-MSP prolongs the network's stable period by 315.625%, 315.625%, and 287.258%, and the lifetime by 245.340%, 237.277%, and 232.475%, with a very high throughput level compared to FBECS, E-CAFL, and LEACH-FC, respectively.
