NanoStreams explores the design, implementation, and system software stack of micro-servers aimed at processing data in-situ and in real time. These micro-servers can serve the emerging Edge computing ecosystem, namely the provisioning of advanced computational, storage, and networking capability near data sources to achieve both low latency event processing and high throughput analytical processing,...
For server and network administrators, it is a challenge to keep an overview of their systems to detect potential intrusions and security risks in real-time as well as in retrospect. Most security tools leverage our inherent ability for pattern detection by visualizing different types of security data. Several studies suggest that complementing visualization with sonification (the presentation of...
In Industrial Ethernet environments, usually only small amounts of data are transmitted. These transmissions must be deterministic to meet hard real-time requirements. But prospectively, also the deterministic transmission of high amounts of data and data streams is required. In this paper, a system based on the modified Peer-to-Peer network Kad called HaRTKad combined with the standardized protocol...
Caregiving a person suffering from dementia or loss of brain cognitive ability due to aging is a big physical, mental and emotional burden to family members. In this paper we present a novel system for assisting caregivers at home. The system employs heterogeneous sensing and artificial intelligence technologies to automatically and unobtrusively monitor the patient; assess possible risks that the...
Microblogging is a new form of blogging in which microbloggers can share their status in short posts. Microbloggers can be kept up to date with current information from microblog senders, however, Web users cannot be simultaneously updated by microblogs, to obtain the most recent information, whilst they browse Web pages since these are not updated in real time. To circumvent this time lag and provide...
Many carpool and ride-sharing solutions have been proposed and even developed in the previous decades, but rarely have they been able to attain a global user base, at least not up until recently. That was mostly because many of them were not initially designed as scalable, leaving their users with a sub-par user experiences as their user base grew, and often their mobile or desktop client reach was...
The Microsoft Kinect camera is a revolutionary and useful depth camera giving new user experience of interactive gaming on the Xbox platform through gesture or motion detection. Besides the infrared-based depth camera, an array of built-in microphones for voice command is installed along the horizontal bar of the Kinect camera. As a result, there are increasing interests to apply the Kinect camera...
To solve the problem that a single processor cannot afford the computational load of the key algorithms in conventional CNC system, a network architecture based on RTnet is proposed in this paper. A resource-consumption and low coupling module in CNC was disjoint first from other modules. RTnet was used for communication between remote modules. Then, by means of Linux Real Time mechanism (LXRT), real-time...
In recent times real-time distributed systems have definitively become peer-to-peer organized. The common interactions are those of different real-time components dealing with sensors or actuators, implementing controllers, performing monitoring and surveillance tasks, and interacting between them in a dynamic decentralized way. There is a need for mechanisms that allow the integration of these independent...
In this paper, we propose a hierarchical architecture to realize a real-time file search in P2P systems. The proposed architecture consists of three layers. Index of files held by the peers in the bottom layer is stored at the peers in the middle layer, and the correlation of peers in the two bottom layers is controlled by the peers in the top layer using the notion of tags. With such notion of tags,...
