We propose a user-centric private key management framework that supports future personal sensing applications. This framework allows for a simple distributed private key system with embedded secure key storage and recovery in multiple parties. The user maintains control over implementation choices and the ability to consent to data being utilised or transmitted by the system. Our proposed framework...
The main goal of pervasive computing is to provide services that can be used by the user in the given context with minimal user intervention. To support such an environment services or the applications in the environment should be able to interact seamlessly, with the other devices or applications present in the environment, to gather relevant information in current context. Main challenge is devices...
Wireless sensor networks (WSNs) receive a lot of attention because of their great potential in monitoring the physical or environmental conditions of military, industry, and civilian. Moreover, mobile cloud computing (MCC) is widely focused, as they can greatly alleviate the hardware limit of mobile devices as well as enable a lot of new mobile applications. All these make the integration of WSNs...
In this paper, we describe wireless grids, an emerging technology that enables ad hoc sharing of resources (such as screen, services and microphone) on edge devices (such as mobile Internet devices, laptops and mobile phones). As wireless devices have become common, and "smart," wireless grids have become practical. To highlight the capabilities of wireless grids to support collaborative...
This paper details the ongoing development of a context-sensitive InfoStation-based architecture supporting the mobile eLearning service provision within a University campus domain. A general overview of this architecture is presented highlighting the main functional entities. Issues concerning the implementation of a context-sensitive service environment within the system are also detailed, including...
There are several radio access technologies providing connectivity for mobile devices. In the future, more and more mobile devices will be capable of supporting more than one access technology. For being able to use these technologies simultaneously, there is a need for multihoming capabilities. Due to the variety of access technologies and the ability to use them simultaneously, new concepts for...
Context-aware applications and services require ubiquitous access to context information about the users or sensors such as preferences, spatial & environmental data, available connectivity, and device capabilities. Systems for the brokering or the provisioning of context data via wireless networks do so with centralized servers or by employing protocols that do not scale well with real-time distribution...
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 on context-aware information regarding personal...
We describe a framework for wireless sensor network (WSN) based mobile mashup applications. The framework consists of four functional components: WSN, mobile gateway, context management platform, and mashup server. The WSN deployed in the application domain senses the physical phenomena and the human-environment interaction and expresses them in sensor readings. The mobile phone is used as the gateway...
This article describes several technical aspects of mobile devices, sensor networks and context sensitive services in information systems developed at the authorpsilas university. It examines key features of the technology and the systems, shows multiple methods of accessing mobile content as well as future research potentials.
Sensory originated data collection and processing has always been a big challenge in wireless sensor networks (WSN). WSN represent a distributed producer of large amount of valuable data required by varied number of applications. In this paper we propose the use of context aware data mules (CADAMULE) as a solution for smart data collection within sensor networks. We present an extension to Context...
