A Scalable Low-Power WSAN Solution for Large-Scale Building Automation

Nowadays, wireless sensor and actuator networks are a hot issue because they can enable the Internet of things at little expense. Research activities mainly focus on one aspect of these networks (e.g. energy consumption) neglecting others (e.g. latency, scalability). Aspects like energy reduction, scalability, quality-of-service, and reliability are key requirements in our envisaged heterogeneous applications for sensor and actuator networks in commercial/residential buildings consisting of 1000+ nodes. In this paper, a stack which meets these requirements is proposed. We found that simulations only are not sufficient when developing WSAN solutions. We showed that it is possible to combine low-power with low-latency on large-scale QoS-aware networks.
