A scalable intelligent room based on wireless sensor networks and RFIDs

We present the analysis, design and implementation of an intelligent classroom whose two main components are realized using two emergent wireless technologies, namely, wireless sensor networks and Radio-frequency identification (RFID) tags. The combination of these two technologies produces a powerful and versatile solution that can offer automated access control to a classroom as well as the monitoring of relevant environment variables such as temperature, humidity and room lighting. We claim that our architecture is readily scalable to a set of interconnected classrooms, by means of a routing protocol especially designed for achieving a multi-hop communication network.
