Abstract
According to the problem that the sensor nodes are highly energy-constrained, a novel dynamic clustering algorithm for WSN, which is in application to object tracking, is proposed. The cluster head selection mechanism takes not only the distance between the cluster head and the sink node but also the received signal strength and the residual energy of nodes into consideration. The analysis result indicates that, the energy consumption of network communication is reduced and the cluster size is optimized. The simulation results show that the novel algorithm can efficiently prolong the lifetime of WSN, especially when the sink node is far from the network.
