Micro-blog is one of the internet applications, and it is newly developed online communication platform to achieve real-time information sharing. Micro-blog becomes quite popular. We analysis the researched approach of detecting hot topic, combine with a variety of related parameters of hot topic, and implement the detection of hot topic through Micro-blog. This paper presents a hot topic detection...
In real-time networked control systems, the end-to-end path delays on the communication network should be bounded in order to satisfy the stringent timing constraints of physical system. While the packet delivery on a single path could be significantly affected by network congestion levels, transmitting duplicate packets along multiple paths can overcome fluctuations of the time delay on a specific...
How the No Relational Data Bases are one of the key factors (among the architecture & infrastructure that supports them) of the complete develop of the IoT, and how they must lead the way to the Web of Things. An example for the e-health.
Immersive, end-to-end applications using mixed multimedia data pose new requirements to the underlying network architecture. These requirements are related to two distinct categories of content delivery. Starting from the overlaying principles of the Future Internet Architecture, the network overlay principles and the Content Delivery Network approach we define our proposed architecture based on two...
The most recent advances in the architecture of the Web allow using it as an excellent platform to deliver experiments and simulations over the Internet. However, there are still some challenges related to the animations' accuracy, to user input collection or to real-time communications that have to be accomplished to properly port native application- based experiments and simulations to the Web....
Machine-to-machine (M2M) solutions are rolling out worldwide and across all industries - possibly being a key enabler of applications and services covering a broad range of vertical markets (e.g., health-care, utilities, transport, education-research and development, logistics etc.). M2M - as a part of the Internet of Things (IoT) - is, at the present, one of the main drivers behind the growth in...
To make real-time marketing tools for online storefronts, it is necessary to understand intentions of customers who are connecting on the storefronts. One of important customer intention may be whether a customer intends to purchase or not in the current session. In this paper, we propose customer purchase probability prediction method based on clickstream data using association rule generation techniques...
This paper proposes the recommendation system which is a new method using k-means clustering of item category based on RFM(Recency, Frequency, Monetary) in u-commerce under ubiquitous computing environment which is required by real time accessibility and agility. In this paper, using a implicit method without onerous question and answer to the users, not used user's profile for rating to reduce customers'...
To improve the operation efficiency and service levels of Bus Rapid Transit (BRT) systems, we propose a novel realtime BRT signal priority approach through two-stage green extension. For social justices, we control traffic signal lights under the people first principle after constructing BRT Internet of Things. This requests us to collect enough traffic information related to BRT vehicles, social...
In applications ranging from radio telescopes to Internet traffic monitoring, our ability to generate data has outpaced our ability to effectively capture, mine, and manage it. These ultra-high-bandwidth data streams typically contain little useful information and most of the data can be safely discarded. Periodically, however, an event of interest is observed and a large segment of the data must...
We live in an era where billions of computers are interconnected. In the very near future, not only computers but also many different digital devices and other physical objects will be seamlessly connected to each other and be able to communicate with little or no human intervention. These interconnected objects are called smart devices, and this concept is called Internet of Things. In this paper,...
It is very tedious and trivial if a network administrator has to manage all the equipment manually. Unfortunately, there are usually numerous and heterogeneous devices over which an administrator must watch. This paper proposes the design and development of an automatic event-driven system to reduce the burden on network administrators. By allowing managers to pre-define the action of some conditions,...
There is an increasing visibility of mobile social games in Japan. The radical growth of item-purchasing in mobile social games provides a new perspective for service engineering. The author comes to recognize that the know-how in mobile social games provides lessons for further general service engineering. The author proposes the concept of virtual-world alchemy for parsing the new paradigm of service...
The number of software applications available on the Internet for distributing video streams in real time over P2P networks has grown quickly in the last two years. Typical this kind of distribution is made by television channel broadcasters which try to make their content globally available, using viewer's resources to support a large scale distribution of video without incurring in incremental costs...
This work presents a test called “sizogram” which characterizes the packet loss vs. packet size behavior of a router. This graph can help us to take some decisions about traffic, e.g. multiplexing or not, the number of samples or frames to be included in a packet, etc. In addition, it can be useful to have a better idea of the internal architecture of the router. Simulations have been carried out...
We introduce and demonstrate the “Helen Keller Phone” system, which enables deaf-blind people to communicate with each other without any support person and talk over the telephone for free with Skype. All communication is done via Body-Braille and is analogous to audio chat communication by non-disabled people. Real-time conversation using Braille instead of audio signals is possible and would dramatically...
This work presents a study of the effect of router buffer size on the subjective quality experienced by players of online games, which is a service with very tight real-time requirements. Quality estimators for other real-time services like e.g. VoIP were developed years ago, and they are commonly used when planning a new telephony system. They mainly use delay and loss as KPI (Key Performance Indicators)...
The rapid growth of broadband connections and home networks has created new application opportunities such as video streaming and remote health care. However, managing and securing the increasingly complicated home networks has remained a serious challenge for most home users who have little technical expertise to manage their home networks and connected devices. Towards this end, we will demonstrate...
This paper proposes a method on reducing processing time of the incoming packets using the signature matching in a router. According to the proposed method, the router has enhanced processing time using signature matching of necessary portion and referring of pre-investigated packet routing table. As a result, this method provides improved quality for real-time traffic such as VoIP and video streaming/conferencing.
Future smart cities are expected to be very large and complex ecosystems, where interactions among the various involved entities may lead to emergent behaviours (system of systems characteristic). Managing better the energy footprint is one of those challenging goals, and the smartgrid may provide a key tool in achieving that. We expect that smart city neighbourhoods will be more autonomous and able...
