Due to power limitation of nodes in wireless sensor networks (WSNs), how to maximize network lifetime has become a critical issue for deployment of WSNs. Although several schemes have been proposed for 2D WSNs, few for 3D WSNs are known. In this paper, we present a scheme for maximizing network lifetime in 3D WSNs through balancing energy consumption, as an extension of the existing scheme for 2D...
