Abstract:
Typical Wireless Sensor Networks (WSN) include some energy autonomous nodes and main powered router nodes. To meet a reasonable lifetime, i.e., years, the autonomous devices have to encompass strong energy constraints. Our target network architecture consists in such wireless autonomous nodes connected to a backbone based on Power Line Communication (PLC) nodes. Our given building automation application scenario runs for a 10 minutes periodic probes sampling, which reports a data frame over the Internet using IPv6. For this purpose, our WSN nodes leverage on open RPL/ContikiOS softwares and typical off the shelf electronic components. In order to optimize the node energy consumption we propose a systemic analysis that includes all the software layers and hardware components. The energy distribution among the different components and the critical software parameters are weighted against the global energy consumption. Thanks to measurements and technical data, we propose a simple model that allows to identify pitfalls and determine optimized solutions. Following our established guidelines, we believe our future WSN monitoring platform will achieve more than 10 years lifetime with the target scenario.
