An IEEE 802.15.4 Wireless Sensor Network for Energy Efficient Buildings
The realization of energy efficient buildings is a very innovative and challenging field of application for wireless sensor networks. To achieve the goal of minimizing the buildings energy consumption and optimizing the energy use, the deployment of sensor nodes is crucial. These sensors, in fact, could be used to measure the power consumed by the different appliances. The eDIANA project, funded by FP7 of the European Commission through the ARTEMISIA framework, is focused on this target. In this chapter, we consider a building composed of apartments, where a number of IEEE 802.15.4 standard-compliant sensors are distributed. Performance, in terms of packet error rate, average delays, and energy consumption, is evaluated, and the impact of the interferences is shown. Moreover, different network topologies are studied and compared. The aim of this study is to show the applicability of the IEEE 802.15.4 standard to the eDIANA application scenario and provide some guidelines for designing the network.
