Communicating materials : modeling and management of energy consumption

Abstract : With the popularization of the Internet of Things, more and more intelligent products appear in our daily life. The McBIM project (Materials communicating with the Building Information Modelling) aims to design a new type of “communicating concrete”: concrete elements equipped with embedded wireless sensor network (WSN). This communicating concrete can measure the physical environment, store the information and exchange data with BIM platforms. One objective is to demonstrate the usefulness of the concept over the whole building lifecycle and the energy management is one of the facing challenges. Meanwhile, the product, user information as well as the large amount of monitoring data bring challenges regarding data management. To solve both issues, this work proposes to couple the physical communicating concrete to an external, digital and intelligent system in order to extend network lifetime. In this thesis, these physical and digital parts are both studied. In the physical part, energy saving methods are reviewed, to understand how to extend the network lifetime. Network routing, in-network data processing and time synchronization are considered to build an energy model for periodic data collection. This energy model is validated with an Arduino-XBee based platform. The experiment shows that the analytic energy estimation model provides an approximate but accurate remaining energy level. It can be used online by nodes or remotely by user to the remaining energy. Energy-related data and collection modes can be managed by the digital part, based on a multi-agent system (MAS). The MAS can not only store monitoring data of communicating elements but also provide energy efficient data collection or organization strategies. Composition of communicating elements may happen in construction or exploitation lifecycle’s phase to reduce energy consumption. A recursive multi-agent architecture is proposed to meet high flexibility requirements. This multi-agent system is implemented on a 3D simulation platform to visualize the communicating concrete and verify the usefulness of our analytic energy model. The recursive multi-agent architecture provides energy efficiency solutions to extend network lifetime and respond to environmental changes.
