Efficient sensor nodes organization is one of the most critical and challenging tasks in building practical wireless sensor networks (WSNs). Due to energy efficiency, clustering has been widely used in WSNs, where each cluster head (CH) is a manager to control its members and collect sensed data from them. Currently, various CH selection techniques have been proposed. However, less emphasis was placed...
Energy conservation has been known as the most important issue for many applications in wireless sensor networks (WSNs). For data gathering in a clustered sensor network, most existing work focuses on fusing data at cluster heads (CHs). However, in target tracking applications, these approaches do not consider that one target is usually detected by sensor nodes in multiple clusters, which leads to...
