Propagation modeling and placement algorithms for wireless sensor networks

The energy efficiency is critical for application of wireless sensor networks, since it is a main precondition for their long-live functionality, small modification costs and reliability. This paper deals with the placement of wireless nodes based on the modeling of radio wave propagation. The methods are realized in a planning tool CANDY Wireless Site Finder that provides optimized topologies of wireless networks under considering of transmitted power, frequencies, propagation environments (in-door/out-door) and obstacles given in CAD-compatible formats. The tool is integrated in the framework of other CANDY tools aimed to efficient planning of heterogeneous wired and wireless networks.
