Sensor networks are increasingly being deployed in a diverse range of applications. Within many of these networks wired sensors, wireless sensors and wired backbone nodes coexist, forming a heterogeneous programmable distributed system. This unique text/reference presents a thorough examination of the middleware that can be used on top of the operating system to configure and operate heterogeneous node platforms and whole sensor networks. The book opens with a review of the application scenarios where networked control systems with wireless sensors may be used, before comparing and analysing the middleware requirements for this set of scenarios. The text then defines middleware architecture for configuration and operation, describing how the proposed mechanisms were integrated in an approach demonstrated live in an oil and gas refinery. The testing and evaluation of this implementation with different hardware and software platforms is also reported. Topics and features: Presents a thorough introduction to the major concepts behind wireless sensor networks Reviews the various application scenarios and existing middleware solutions for wireless sensor networks Discusses the middleware mechanisms necessary for heterogeneous wireless sensor networks Provides a detailed examination of platform-agnostic middleware architecture, including important implementation details for each part of the architecture Investigates the programming paradigms for wireless sensor networks, and for heterogeneous sensor networks in general Describes the results of extensive experimentation and testing, demonstrating that the generic architecture is viable for implementation on multiple platforms Providing helpful insights for students and researchers alike, this book is ideally suitable for use as a reference in both introductory and advanced courses on embedded devices. Practitioners seeking to learn more about how these systems work will also benefit from the in-depth coverage.

Modern industrial systems are often highly automated, with hundreds or even thousands of sensors and actuators monitoring the various processes, overseen by a distributed control system (DCS). Such control systems increasingly make use of wireless communications, yet these must still satisfy all safety-critical requirements. This unique text introduces the components, operations, industry protocols and standards of DCS, and shows how to include wireless technology in their design while guaranteeing the desired operation characteristics. The book not only discusses the theory, but also presents insights and results gained from extensive practical experience in implementing and testing systems within a specific industrial setting. Topics and features: Reviews the concepts, components and architectures supporting DCS Examines the operations that the DCS implements, covering human-machine interfaces, diagnostics and maintenance interfaces, and controllers Discusses industrial control system and wireless network protocols Reviews scheduling in wireless sensor networks Describes a latency model for heterogeneous DCS with wired and wireless parts, that predicts monitoring latencies, command latencies and closed loop latencies Explains how to plan operation timings systematically Introduces measures and metrics for performance monitoring and debugging, and describes how to add performance monitoring and debugging to a system Presents experimental results to validate the planning approach, based on an application test-bed This practical guide for real-world implementation will be of considerable interest to a wide audience, from professional engineers to researchers and students. It is suitable as a supporting text for courses covering industrial systems, networks, real-time systems, wireless sensor networks or embedded systems.
