There is a growing interest in design and implementation of cyber-physicalcontrol systems over wireless sensor and actuator networks (WSANs). Thanks tothe use of wireless communications and distributed architectures, these systemsencompass many advantages as compared to traditional networked control systemsusing hard wirelines. While WSANs are enabling a new generation of controlsystems, they also introduce considerable challenges for quality-of-service(QoS) provisioning. In this chapter we examine some of the major QoS challengesraised by WSANs, including resource constraints, platform heterogeneity,dynamic network topology, and mixed traffic. These challenges make it difficultto fulfill the requirements of cyber-physical control in terms of reliabilityand real-time. The focus of this chapter is on addressing the problem ofnetwork reliability. Specifically, we analyze the behavior of wireless channelsvia simulations based on a realistic link-layer model. Packet loss rate (PLR)is taken as a major metric for the analysis. The results confirm theunreliability of wireless communications and the uncertainty of packet lossover WSANs. To tackle packet loss, we present a simple solution that can takeadvantage of existing prediction algorithms. Simulations are conducted toevaluate the performance of several classical prediction algorithms used forpacket loss compensation. The results give some insights into how to deal withpacket loss in cyber-physical control systems over unreliable WSANs.
