Due to ongoing changes in the power grid towards decentralised and highly volatile energy production, smart electricity meters are required to provide fine-grained measurement and timely remote access to consumption and production data. This enables flexible tariffing and dynamic load optimisation. As the power grid forms part of the critical infrastructure of our society, increasing the resili...

Communication software for hand-held devices must be flexible and efficient to deliver the necessary Quality of Service (QoS) to multimedia applications such as real-time audio and video, video on-demand, electronic mail and fax, and Internet telephony. CORBA Object Request Brokers (ORBs) are an emerging middleware standard targeted for distributed applications. The stringent memory constraints...

Software Platform is a middleware component of Smart Space to coordinate and manage all modules. Location-awareness is a common feature of many modules. Current several typical methods for distributed systems can hardly be competent for both the role of Software Platform and accommodating locationawareness simultaneously. Aiming at this, we present our method: SLAP (Smart Location-awareness-Acc...

Smart Fitting Rooms offer great potential to enhance customer shopping experience in retail fashion stores. To this end, they leverage auto-id technology to detect product selections of customers and offer additional services based on these selections on screens within the Smart Fitting Room cabins (e.g., product recommendations or Omnichannel services). While current implementations mainly rel...

Service personalization is an important goal for any smart environment. Comfort systems may be adjusted in an automatic way when a given user is present, and multimedia devices may offer a music or movie catalog with favorite contents or may even pick one of them for the user. To achieve this goal, we propose a Service Oriented Architecture implementation based on multiagent systems. We special...

With the Virtual State Layer (VSL), an abstraction for software-based orchestration of smart spaces is presented. The aim of the VSL is to ease the programming of orchestration software while not limiting its functionality. The VSL primarily provides: the virtualization of that part of the real world that can be orchestrated via sensors and actuators, a base for the creation of portable orchest...

Recent years, flash memory based Solid State Drives (SSDs) become a mainstream choice in mobile computers. To protect confidential data from being leaked, users have to run secure software to securely delete the needless files. However the traditional secure deletion software will not work for SSDs. To solve the problem, we proposed a smart secure deletion method called SmSD to clean up the sen...

Traditional utility metering is to be replaced by smart metering. Smart metering enables very fine grained utility consumption measurements. These fine grained measurements raise privacy concerns due to the lifestyle information which can be inferred from the precise time at which utilities were consumed. This paper outlines two privacy respecting time of use billing protocols for smart meterin...

Traditional classrooms involve the use of face-to-face interaction and a whiteboard or projector, but the inabilities to micro manage the environment between the teaching staff and the student calls for a need for a smart interactive learning environment. The aim of this work is to develop evidence and experiments for an architecture for a smart learning environment. This paper discusses the de...

The main goals of smart metering are the reduction of costs, energy and CO2 by the provision of actual metering information to the providers and the customer. They allow for flexible possibilities to influence the customers’ energy consumption behavior and to adapt dynamically the power generation and distribution to the requested energy by smart grids. Metering devices are under control of gov...
