A new plugin for optimal sensor placement using the Building Information Modeling.

A mathematical model based on integer linear programming for sensor placement.

We take into account: zone size, exclusion zone, sensor field of view and placement.

Application: home support to equip an Ambient Assisted Living.

In this paper, we present a plugin for the optimal placement of sensors in a smart home. Our approach includes the Building Information Modeling (BIM) which is a plan that describes the building layout.

This plugin use the CSTB EveBim viewer for loading IFC file representing the digital building's model. We use then, a mathematical model based on a mixed integer linear program, to determine the optimal sensor placement according to building and sensors characteristics.

The results show the efficiency of the proposed algorithm and the developed plugin. We obtain an optimal solution after few seconds, and we show the sensor placement on the building digital model.

We show the relevance of the proposed plugin to equip room of retirement home or ambient assisted living in order to identify occupant activity for home support application.
