Abstract:

One of the fundamental services provided by Wireless Sensor Networks (WSN) is the surveillance of a Field of Interest (FoI). Sensors may monitor physical properties such as temperature, humidity, pressure, and air quality, or track the motion of objects moving within the FoI. For static observations, a relevant performance metric that quantifies the quality of surveillance is the coverage of the FoI. For the observation of moving objects, a relevant performance metric is the target detection probability of a target moving within the FoI.

In this talk, I will present tools for the analytical evaluation of coverage and target detection probability in heterogeneous WSN. The heterogeneity in the sensing areas is motivated by the need of a multi-modal approach in surveying the FoI. I will show how these tools can be used to derive critical network parameters such as deployment density and sensing area size for the case of stochastic sensor deployment, or optimal node location for the case of deterministic sensor placement. My analysis will be based on measures for "infinite" sets from the fields of Integral Geometry and Geometric Probability.
