In state-of-the-art Pervasive Computing, it is envisioned that unlimited access to information will be facilitated for anyone and anything. Wireless sensor networks will play a pivotal role in the stated vision. This reflects the phenomena where any situation can be sensed and analyzed anywhere. It makes heterogeneous context ubiquitous. Clustering context(More)
User information and communication resources - such as precise location information and direction, altitude, light, and humidity measurements (via sensors) - are becoming more available in end devices. This increasing range of information can enable context-aware informational services as well as linking digital objects to physical objects a user is(More)
Currently, 3GPP is reinventing the telecom model of services in wireless Internet — a model that is not well suited to (1) meet the demands for new modes of personal mobile communication, enabled by wireless packet services and multimedia devices, or (2) the ability to deal with increasingly heterogeneous wireless infrastructure (one interpretation of 4G).(More)
Mobile telecommunication is evolving rapidly. People no longer only communicate with each other regardless of time and place, but also share other information that is important for tasks with which they are involved. In response to this growing trend the MediaSense framework addresses the intelligent delivery of any information to any host, anywhere, based(More)
Packet-oriented access to cellular networks enables us to deliver multimedia content to mobile users. As cellular networks will continue to deliver circuit switched voice for some time to come, care must be taken to avoid interference between these delivery mechanisms, while maximizing the range of services and the number of users. Smart delivery of(More)
A novel idea presented in this paper is to deploy the Open Flow technology in wireless sensor networks that can lead to a significant achievement in Internet of things and cloud computing arena through network virtualization. Two new abstract layers namely Common platform layer and virtualization layer can be added at the top and bottom of a preset(More)
Next generation context-aware mobile applications will require a continuous update of relevant information about a user's surroundings, in order to create low latency notifications and high quality of experience. Existing mobile devices already contain a large number of built in sensors which are capable of producing huge amounts of sensor data, exceeding(More)
