Intelligent Buildings Analog Monitoring Wireless Sensor Network Topology Control

Although most wireless terrestrial networks are based on two-dimensional (2D) design, in reality, such networks operate in three dimensions (3D). Since most often the size (i.e., the length and the width) of such terrestrial networks is significantly larger than the differences in the third dimension (i.e., the height) of the nodes, the 2D assumption is somewhat justified and usually it does not lead to major inaccuracies. However, in some environments, this is not the case; the building, the underwater, atmospheric, or space communications being such apparent examples. In fact, recent interest in underwater acoustic ad hoc and sensor networks hints at the need to understand how to design networks in 3D. Unfortunately, the design of 3D networks is surprisingly more difficult than the design of 2D networks.During the research and designing of my task, I referenced a lot of literatures, studied some previous algorithms. In this paper, we put forward a wireless sensor network system to monitor the temperature of the building intellectively, introduce the hardware design, build up a stack system structure, and then we consider the coverage and connectivity issues of 3D networks, and we verify by simulation that our placement strategies indeed guarantee ubiquitous coverage. We also provide a distributed topology control algorithm that can be used by each sensor node to determine its cell ID using a constant number of local arithmetic operations provided that the sensor node knows its location. We also validate our results by simulation.We believe that our approach and our results presented in this paper could be used for extending the processes of 2D network design to 3D networks...
