Executive Summary

Wireless Sensor Networks (WSNs) are gaining an increasing industry wide adoption. However there remain major challenges such as network dimensioning and node placement especially in Built Environment Networks (BENs). Decisions on the node placement, orientation, and the number of nodes to cover the area of interest are usually ad-hoc, which leads either to poor coverage or over-provisioned, over sized networks. Ray tracing tools are traditionally employed to predict RF signal propagation however such tools are primarily intended for outdoor environments and do not accurately predict RF performance in buildings.
