“…Finally, while pervasive computing and wireless sensor networks started out as separate fields, there is a strong convergence towards middleware-based solutions that combine the two paradigms. Thus, numerous research approaches propose programming abstractions and middleware for wireless sensor networks [45,46,86], or focus more particularly on adaptation in sensor networks [68,130].…”

Service-oriented computing is now acknowledged as a central paradigm for Internet computing, supported by tremendous research and technology development over the last 10 years. However, the evolution of the Internet, and in particular, the latest Future Internet vision, challenges the paradigm. Indeed, service-oriented computing has to face the ultra large scale and heterogeneity of the Future Internet, which are orders of magnitude higher than those of today's service-oriented systems. This article aims at contributing to this objective by identifying the key research directions to be followed in light of the latest state of the art. This article more specifically focuses on research challenges for service-oriented middleware design, therefore, investigating service description, discovery, access, and composition in the Future Internet of services.

“…This component will publish an event whenever a traffic light changes state (i.e., from green to red or from red to green-amber is handled by hardware within each traffic light and is not controlled by SCOOT). 4 The "SCOOT + light state detector" also supports a request/response mechanism to retrieve information, such as description and the location, about a given junctions. The components we have described so far have no semantic connection with finding buses that are near red lights.…”

Abstract. Providing citizens with accurate information on traffic conditions can encourage journeys at times of low congestion, and uptake of public transport. The TIME project (Transport Information Monitoring Environment) has focussed on urban traffic, using the city of Cambridge as an example. We have investigated sensor and network technology for gathering traffic data, and have designed and built reusable software components to distribute, process and store sensor data in real time. Instrumenting a city to provide this information is expensive and potentially invades privacy. Increasingly, public transport vehicles are equipped with sensors to provide arrival time estimates at bus stop displays in real-time. We have shown that these data can be used for a number of purposes. Firstly, archived data can be analysed statistically to understand the behaviour of traffic under a range of "normal" conditions at different times, for example in and out of school term. Secondly, periods of extreme congestion resulting from known incidents can be analysed to show the behaviour of traffic over time. Thirdly, with such analyses providing background information, real-time data can be interpreted in context to provide more reliable and accurate information to citizens. In this paper we present some of the findings of the TIME project.

“…The system is based on a novel component-based middleware called SBUS (Stream BUS) [12] which supports peer-to-peer event-based communication including both continuous streams of data (e.g., from sensors), asynchronous events, and synchronous RPC. In SBUS each component is divided into a wrapper, provided by the SBUS framework, and the business logic that makes up the component's functionality.…”

Today, software engineering is challenged to handle more and more large-scale distributed systems with guaranteed quality-of-service. Component-based architectures have been established to build such systems in a more structured and manageable way. Modern architectures often utilize eventbased communication which enables loosely-coupled interactions between components and leads to improved system scalability. However, the loose coupling of components makes it challenging to model such architectures in order to predict their quality properties, e.g., performance and reliability, at system design time. In this paper, we present an extension of the Palladio Component Model (PCM) and the Palladio software quality prediction framework, enabling the modeling of event-based communication in component-based architectures. The contributions include: i) a meta-model extension supporting events as first class entities, ii) a modeto-model transformation from the extended to the original PCM, iii) an integration of the transformation into the Palladio tool chain allowing to use existing model solution techniques, and iv) a detailed evaluation of the reduction of the modeling effort enabled by the transformation in the context of a real-world case study.
