摘要：The wireless sensor networks (WSN) typically consist of a large number of intelligent sensor nodes randomly deployed in an area of interest to supervise or monitor various phenomena (temperature, pressure, humidity ..). During these last years the research in wireless sensor networks has become a very rich field because of the challenges presented in their applications such as limited energy source, limited memory, limited processing capacity, low transmission rate , low bandwidth and high latency caused by the nature of the shared radio channel. Among the most common methods used to ensure effective communication between the nodes of the sensor network is to organize the network into several groups, called clusters; these clusters are disjoint and non-overlapping, each cluster must designate a node cluster chief also called Cluster Head (CH) responsible for managing all the computational operations, routing and data aggregation. This paper reports an approach to grouping (clustering) the WSN in order to balance the load of broadcast of traffic within the network and thus conserve energy and extend the lifetime of the entire network.
