This paper describes a software system prototype for automated game servers deployment and configuring customized game servers on demand. The described system has a web interface which allows customers to create accounts, purchase, services, and gain access to and configure their purchased web servers. This service consists of a website which acts as an interface for customers to purchase subscriptions,...
AeroMACS (Aeronautical Mobile Airport Communications System) is an aeronautical wireless communication standard which provides high-speed fix/mobile network on the airport surface. AeroMACS is expected to gain the safety and efficiency of the airport operations by allowing the stakeholders such as air navigation service providers, airline companies, and airport authorities to exchange massive data...
Sound design has received little attention in location-based games research. Typically, existing prototypes heavily rely on visual information with sound only having a marginal role in the game design and development process. This paper investigates the role of sound as primary interface for conveying game information and creating engaging gaming experiences. As a case study, we present SoundPacman,...
Serious disasters have been annually occurred in Japan. Particularly, in the Great East Japan Earthquake that occurred on March 11, 2011, the communication infrastructure was seriously damaged over wide areas. Due to such situation, more resilient network infrastructure that does not stop under challenged communication environment is required. In this paper, we propose a disaster information system...
Aeronautical Mobile Airport Communications System (AeroMACS) is being standardized in order to provide new broadband wireless communications on airport surface. AeroMACS will be used for voice-based Air Traffic Control (ATC) services in the future as it is recommended in standards and recommended practices (SARPs) of the International Civil Aviation Organization (ICAO). Therefore, we evaluated the...
The design of modern medical data information systems is driven by the need to collect and present data to authorized users. For collected medical data to be effective and improve patient treatment it must be transported from a device, aggregated, and analyzed to produce results that can be shared with care providers. Medical data may be analyzed and used years after collection at different locations...
This paper presents a first step into theconstruction of an innovative web-based eLearning platformfeaturing Learning Analytics and Gamification called ICTFLAG. The main goal and key decision at this initial stage of theplatform development is the search and selection processes of themost suitable software development framework to guide andsupport the effective construction of the platform. Despite...
To maintain acceptable levels of security, organizations must manage their IT assets and related vulnerabilities. However, this can be a considerable burden because their resources are often limited. This paper introduces a technique and system architecture that monitor the vulnerability of the IT assets on an organization's administrative networks. We use open information and standardized, non-proprietary...
In this paper we present our ongoing study and deployment efforts for enabling FPGAs in datacenters. An important focus is to provide a quantitative evaluation of a wide range of heterogeneous system designs and integration options, from low-power field-programmable SoCs to server-class computer nodes plus high-capacity FPGAs, with real system prototyping and implementation on real-life applications...
This article proposes a path for doing Data Science using browsers as computing and data nodes. This novel idea is motivated by the cross-fertilized fields of desktop grid computing, data management in grids and clouds, Web technologies such as NoSQL tools, models of interactions and programming models in grids, cloud and Web technologies. We propose a methodology for the modeling, analyzing, implementation...
Network management is a major issue in information world which requires high effective implementation to have properly structured information system for providing accurate data across a wide area. Efficiently functioning systems and management in a network, is necessity of up growing information sector. This needs a proper network for providing precise and accessible services to the clients over a...
Providing robust content delivery service, such as Video on Demand, with efficient wireless resource usage is important for mobile users. To achieve this, we have proposed a proactive content caching scheme utilizing transportation systems (e.g., train.) Because our previous prototype is immature and has a scalability issue, in this paper, we introduce efficient transmission mechanism of Interest...
The Petabyte-scale data volumes in Earth Observation (EO) archives are not efficiently manageable with serial processes running on large isolated servers. Distributed storage and processing based on ‘big data’ cloud computing frameworks needs to be considered as a part of the solution.
Lightweight virtualization, as implemented by application container solutions such as Docker, have the potential to revolutionize the way multi-tier applications are developed and deployed, especially in the cloud. The success of application containers can be partly attributed to their ability to share resources with the underlying platform that hosts them. As such, the isolation provided by such...
In post disaster situations it is vital to restore voice and data communication services quickly. Currently, portable wireless systems are used as a temporary solution. However, these solutions have a lengthy setup, limited coverage, and typically require the use of expensive satellite backhaul. Solutions based on cognitive radio mesh networks have been proposed, to exploit self-configuration and...
We propose distributed media computing method for high performance and massive computing of media processing. By dividing media streams temporally and spatially, and processing them, the method reduces the elapsed time of media processing and improves the system scalability. The experiment results show the method increases the elapsed time. The performance degradation could be mitigated using high-speed...
Highly available metadata services of distributed file systems are essential to cloud applications. However, existing highly available metadata designs lack client-oriented features that treat metadata discriminately, leading to a single metadata fault domain and low availability. After investigating the workload characteristics of Hadoop, we propose Client-Oriented METadata (COMET), a novel highly...
The proliferation of Social Networking Services (SNS) has highlighted the need of providing reliable but efficient mechanism to report information from mobile users to the data center. In this paper, a mechanism to reduce periodic update of position and sensor data for activities recognition from mobile device is proposed. To improve the reporting mechanism, variance analysis from sensor data captured...
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...
The Versatile and Ubiquitous Secret Sharing System, a cloud data repository secure access and a web based authentication scheme. It is designed to implement the sharing, distribution and reconstruction of sensitive secret data that could compromise the functioning of an organisation, if leaked to unauthorised persons. This is carried out in a secure web environment, globally. It is a threshold secret...
