Due to the decreasing production costs of IT systems, applications that had to be realised as expensive PCBs formerly, can now be realised as a system-on-chip. Furthermore, low cost broadband communication media for wide area communication as well as for the realisation of local distributed systems are available. Typically the market requires IT systems that realise a set of specific features for the end user in a given environment, so called embedded systems. Some examples for such embedded systems are control systems in cars, airplanes, houses or plants, information and communication devices like digital TV, mobile phones or autonomous systems like service- or edutainment robots. For the design of embedded systems the designer has to tackle three major aspects: The application itself including the man-machine interface, The (target) architecture of the system including all functional and non-functional constraints and, the design methodology including modelling, specification, synthesis, test and validation. The last two points are a major focus of this book. This book documents the high quality approaches and results that were presented at the International Workshop on Distributed and Parallel Embedded Systems (DIPES 2000), which was sponsored by the International Federation for Information Processing (IFIP), and organised by IFIP working groups WG10.3, WG10.4 and WG10.5. The workshop took place on October 18-19, 2000, in Schloß Eringerfeld near Paderborn, Germany. Architecture and Design of Distributed Embedded Systems is organised similar to the workshop. Chapters 1 and 4 (Methodology I and II) deal with different modelling and specification paradigms and the corresponding design methodologies. Generic system architectures for different classes of embedded systems are presented in Chapter 2. In Chapter 3 several design environments for the support of specific design methodologies are presented. Problems concerning test and validation are discussed in Chapter 5. The last two chapters include distribution and communication aspects (Chapter 6) and synthesis techniques for embedded systems (Chapter 7). This book is essential reading for computer science researchers and application developers.

Advances in the field of wireless sensor networks (WSNs) over the last decade have led to a great number of available hardware platforms and operating systems for embedded devices. With the upcoming research area called Internet of Things (IoT) even more new platforms appeared. Consequently, we are now faced with a vast amount of different embedded systems, ranging from tiny microcontrollers to comparably powerful smartphones. Unfortunately, this diversity of hardware architectures has not yet been fully addressed by any generic software architecture. Various operating systems for embedded devices are available, however, each of them cover only a few architectures. Using Java is not possible on tiny microcontrollers because of the lack of a Java Virtual Machine (JVM) on these platforms. Similarly, the entire field of testing is not geared towards dealing with the amount of heterogeneity. Testing environments are mostly homogeneous, and it is not possible to evaluate ideas on large-sized networks consisting of heterogeneous nodes. In this work, we present techniques to address the aforementioned problems. We introduce modern programming paradigms known from desktop computers and transfer these ideas to embedded systems. Furthermore, we built a testing platform consisting of heterogeneous wireless nodes and sensors. Finally, we present novel communication channels that are able to connect nodes that cannot communicate physically, or even real nodes with simulated ones. Hence, this work consists of three parts: While the dominant programming language on embedded systems is still C, we show that more efficient and comfortable results can be achieved by utilizing modern programming paradigms using C++. We therefore transfer the established template-based design of well-known libraries such as the Standard Template Library (STL) or Boost to embedded systems. After thoroughly studying the design of a software architecture based on C++, we present a successful implementation of our ideas: The Wiselib, a generic algorithms library for distributed heterogeneous embedded systems. To run algorithms in an appropriate test scenario, we built a heterogeneous testbed, consisting of different types of nodes and sensors. To this end, we installed self-designed low-cost load sensors based on strain gauges beneath the floor of a hallway in our institute, capable of identifying passers-by. The load sensors are wired to sensor nodes, which in turn allows for the design of sophisticated algorithms doing in-network data processing. The nodes are additionally connected to passive infrared sensors (PIRs) and actuator units---light-emitting diodes (LEDs) and speakers---for interaction with passers-by. The hallway serves as a platform for various application areas. Examples are target tracking, medical testing, and interactive games. Finally, we present virtualized communication links. This technique allows to connect nodes with incompatible radio transceivers or at distant locations. Furthermore, it can be used to let real nodes communicate with virtual nodes in a simulator, which allows for novel debugging mechanisms for distributed embedded systems such as the instantiation of unit tests.

The IFIP TC-10 Working Conference on Distributed and Parallel Embedded Systems (DIPES 2004) brings together experts from industry and academia to discuss recent developments in this important and growing field in the splendid city of Toulouse, France. The ever decreasing price/performance ratio of microcontrollers makes it economically attractive to replace more and more conventional mechanical or electronic control systems within many products by embedded real-time computer systems. An embedded real-time computer system is always part of a well-specified larger system, which we call an intelligent product. Although most intelligent products start out as stand-alone units, many of them are required to interact with other systems at a later stage. At present, many industries are in the middle of this transition from stand-alone products to networked embedded systems. This transition requires reflection and architecting: The complexity of the evolving distributed artifact can only be controlled, if careful planning and principled design methods replace the - hoc engineering of the first version of many standalone embedded products.
