Cyber-physical systems integrate Information and Communications Technology (ICT) functions to the physical elements of a system for monitoring and controlling purposes. As the power grid is evolving into a Smart Grid with the employment of ICT, it is becoming one of the largest cyber-physical systems, where physical grid components are monitored and controlled based on the interactions on the cyber space. In this context, Wireless Sensor Networks (WSNs) are anticipated to be heavily utilized in Smart Grid and many other cyber-physical system monitoring applications thanks to their low cost and ease of deployment. Nevertheless, there are certain challenges that need to be addressed before WSNs are widely adopted in cyber-physical systems. Low data rates, limited battery lifetime and the difficulties in provisioning Quality of Service (QoS) are among the fundamental challenges. WSNs use low power communication links in dense deployments, which introduces delays in channel access over a limited transmission range. Meanwhile, sensor nodes run on batteries whose life can be extended with ambient energy harvesting or energy conservation techniques while the network lifetime is still short in comparison to the long-lasting operation that is desired by cyber-physical systems. In this talk, we will introduce two recent proposals that address latency and network lifetime drawbacks of WSNs. In the first study, the channel access mechanism of IEEE 802.15.4 is modified to allow high priority packets to be fast tracked. In the second study, a recent technology, i.e. wireless power transfer via electromagnetic radiation is utilized to implement perpetual WSNs. This talk will provide the essential background on cyber-physical systems and WSNs for the non-expert audience while expert audience will be exposed to our cutting-edge research results on WSN-based cyber-physical system monitoring.
