The Internet of Things (IoT) is now shaping our cities to make them more connected, convenient, and intelligent. However, this change will highly rely on extracted values and insights from the big data generated by our cities via sensors, devices, and human activities. Many existing studies and projects have been done to make our cities smart, focusing more(More)
Ontologies will be crucial for the future development of Next Generation Service Delivery Platforms. While various projects have defined ontologies for the mobile domain, there is yet little agreement on a common semantic model. One reason is the intrinsically hard problem of finding, using, mapping and evolving already existing ontologies. In this paper we(More)
Services are becoming the foundation of the Telecommunication and Internet world. The ability to fast and cost-efficient create, provision and manage services will become a driving force in the overall competition. A major step forward for a rich service environment is to give end-users the ability to create their own services. The SPICE platform provides(More)
Mobile agents are a new paradigm for distributed computing that is especially well suited for mobile computing over global wireless networks. This paper describes the approach taken in the ACTS On TheMove project to integrate a mobile agent system into the Mobile Application Support Environment (MASE), a middleware for mobile computing. In this project, an(More)
The expected huge increase in the number of IoT data sources (sensors, embedded systems, personal devices etc.) will give rise to network-edge computing, i.e., data pre-processing, local storage, and filtering close to the data sources. Specifically, data reduction at the network edge (e.g., on an IoT gateway device or a mini-server deployed locally at an(More)
The ACTS OnTheMove project is investigating a mobile middleware, which supports applications for the mobile user. Because of the high communication costs and other technical problems resulting from today’s wireless networks technology, support for disconnected operations are of high importance for the mobile user. The emerging mobile agent technology is a(More)
In this paper we present a context-management middleware for Next Generation Networks (NGN). Our middleware, called ICE, is based on the concept of <i>Context Sessions</i>. In contrast to earlier work in context management, we apply NGN design principles to context management and separate signalling from context exchange. We believe that ICE provides an(More)
