Case Study of a Wireless Sensor Network for a Building Monitoring Application

This paper focuses on building monitoring systems that are essentials to identify and improve the building energy performances in an efficient way. The major problem concerns the energy efficiency of the radio communications in order to extend the Wireless Sensor Network lifetime. In this goal, we show why it is important to have a cross-layer approach in the design of such system. More particularly, we show the different levels of optimization and the importance to take into account the physical layer performances in the MAC layer assessment.
