There are a number of different system concepts that have gained much relevance in the area of embedded systems over the past couple of years. First, there is the classic concept of embedded systems where the focus is on control systems for physical processes. Secondly, the notion of pervasive computing has evolved, where the vision foresees everyday objects having some form of computation capacity and, in most cases, sensing and communication facilities. Thirdly, the notion of wireless sensor networks has arisen, where small computing devices are able to sense their environment and cooperate in order to achieve a well-defined goal. These three types of quite diverse systems share a lot of commonalities on the one hand and, on the other hand, have some complementary aspects in common that make a combination of these systems into a coherent system vision promising. In particular, the important notions of control, heterogeneity, wireless communication, dynamic and ad-hoc nature and cost are prevalent to various degrees in each of these systems. A future system concept needs to combine the strong points of all three system concepts in at least these functional aspects. It has to provide support for the control of physical processes like today’s embedded systems do, have as good support for device heterogeneity and spontaneity of usage as required by pervasive and ubiquitous computing approaches, and has to be as cost efficient and wirelessly agile as wireless sensor networks are. These new systems consist, therefore, of individual entities or objects that jointly strive to reach a common goal, which will typically be a goal in sensing or control, and are dynamically and loosely federating themselves for cooperation, taking care not to overtax their available resources. This book presents a roadmap to these concepts which are summarized as cooperating objects.
Wireless Sensor Networks exemplify a broader field focused on Cooperating Objects, aiming to realize Weiser's vision of the disappearing computer. These small computing devices, equipped with wireless communication, can autonomously organize into networks to accomplish shared tasks. This book presents the research roadmap for Cooperating Objects as envisioned by the Embedded WiSeNts consortium, alongside its industrial and academic partners. Launched in September 2004 as a Coordination Action funded by the European Commission under IST/FP6, the Embedded WiSeNts project aimed to assess the state of Cooperating Objects and formulate a research roadmap for future programs. The book is the culmination of two years of research. Despite the excitement surrounding wireless sensor networks, significant challenges remain before they can transition from experimental technologies to effective real-world solutions. This insightful book highlights the research challenges, gaps, and trends related to cooperating objects and wireless sensor networks, making it essential reading for researchers in the field. It underscores the potential for ubiquitous computing through embedded wireless sensor networks to drive significant social and economic changes, emphasizing the need to translate sophisticated research into viable products and services. Overall, the book summarizes the current state of sensor and cooperating object research while sugge
