Résumé :	Modern wireless communications advancements and miniaturization components in the field of electronics have led to the development of lower-cost, multi-functional microsensors. A very new useful type of network, called Wireless Sensor Networks (WSNs), has emerged in recent decades, acting as generators and relay data by controlling interesting physical phenomenon. Although WSNs have conquered almost all areas of everyday life, their development has not yet reached a fully satisfactory level of maturity. Then, some solutions to certain of their problems need to be improved, particularly that of energy conservation. This valuable resource of energy has to be sufficiently available until a WSN reaches its mission. In order to increase WSN lifetime, numerous protocols have been designed to address this problem of power consumption. The pioneer of these protocols was Low Energy Adaptive Clustering Hierarchy (LEACH) protocol and other enhancement variants were subsequently created in this context. In this work, a new protocol named Area Splitting for Clustering (ASC) that reduces energy consumption and increases network lifetime is proposed. The performance evaluation of ASC has been carried out and showed that it outperforms those of Leach and its variant protocols.
