on computer-aided design of energy efficient wireless sensor networks
The paper discusses different aspect of the energy efficiency in wireless sensor networks (WSN), which is a critical precondition for long life, reduced modification costs and increased reliability of WSN. At first, a brief overview of wide-spread WSN systems is provided. Further, the most important tradeoffs between different factors influencing energy efficiency and quality-of-control at different network layers are discussed. Further, a computer-aided design (CAD) of WSN is demonstrated on the example of the planning tool CANDY Wireless Site Finder that provides the design of optimal topology for WSN under considering of transmitted power, frequencies, propagation environments (in-door/out-door) and obstacles given in CAD-compatible formats. The tool is integrated within the framework of further CANDY tools aimed to efficient planning of heterogeneous wired-wireless networks.
