A hierarchical wireless network architecture for building automation and control systems: Implementation and simulation study

Most of the energy consumed in the United States comes from residential and commercial buildings. This fact has increased the research interest in building automation systems that can lead to energy efficient buildings. These systems are essentially distributed and depend on a communication network that gathers sensing data from the environment, processes the results and provides feedback by sending commands to actuators. Wireless sensor networks have been proved as a flexible and cost saving solution for building automation. In this thesis, we present an implementation of a hierarchical wireless network for building automation and control systems using TinyOS. Also, a simulation study of data aggregation on top of the hierarchical wireless network is carried out to see its impact in the network performance.
