Architecture Design of an Integrated Communication and Broadcasting Network
Due to the 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, the authors present a scheme to maximize network lifetime for 3D WSNs through balancing energy consumption, as an extension of the existing scheme for 2D WSNs proposed recently. Same as, they formulate the energy consumption balancing problem as an problem of optimal distribution of transmitting data by combining the techniques of sphere-corona based network division, mixed-routing and data aggregation.
