A Secure, Open Source WSN-based Monitoring System using CM5000 Motes

In today's automated, interconnected world, remote monitoring and control are necessary procedures for the operation of several systems. The monitoring of environmental data is one of the most common telemetering activities, useful for many systems, from electricity microgrids, to smart buildings and remote facilities. Wireless Sensor Networks (WSNs) provide the technology for collecting, transmitting and processing information in a low-cost and integrated manner. They are functionally and energy-independent, easily deployed and scalable. In this paper, we present the design, implementation and testing of a secure monitoring system based on WSNs consisting of Advanticsys CM5000 motes. The sensor nodes collect a variety of environmental measurements and send them to a centralized data repository. Data transmissions inside the WSN are protected through encryption. At the repository, the measurements are presented to the end user in a graphical form using open source cloud technologies.
