Demand response is widely employed by today's data centers to response to the increasing of electricity cost. To incentivize users of data centers participate in the demand response programs, i.e., breaking the split incentive hurdle, some prior researches proposed market-based mechanisms such as dynamic pricing and static monetary rewards. However, these mechanisms are either intrusive or unfair...
We study optimal monitor placement for intrusion detection in networks with persistent attackers. The problem is modeled as a stochastic game in which the attacker attempts to control targets by delivering malicious packets while the defender tries to detect such attempts. The state of the game is determined by the target end-systems in the network, each of which can be in either a healthy or a compromised...
Capturing and retaining the attention of students while learning complex topics like modeling and simulation is a critical task. In discrete-event simulation (DES), educators rely on examples like queueing systems in fast food restaurants or manufacturing organizations to provide the necessary context for learning. In many instances, these examples fall short in capturing the attention of students,...
Component-based programming is predicted to become mainstream practice in software engineering in the next few years. Students need to get familiar with modern programming approaches such as this one, but including the topic into curricula is not a simple task. This paper presents our approach to teaching component-based programming. The goal of Component-Based Programming course was to practically...
Recently, Wu et al. introduced a general approach based on distributed computing named Job-Level (JL) Computing. JL Computing has been successfully used to construct the opening books of game-playing programs.? In order to support large-scale computing problems such as solving 7×7 killall-Go, or building opening books for 9×9 Go or Connect6, record databases are used to store JL computing results...
Utilization of Digital Signage (DS) in the tourism sector should be used as medium to provide information of interest for tourists. In Indonesia, many places of supporting tourism such as shops, restaurants and entertainment using DS as medium of information and communication to their customers. Usually DS using multimedia content such as video, images and text displayed on the screens are repeatedly...
In today's life, the mobile phone is an essential device for the modern human. The people play installed games in the mobile device to pass the time and express emotions. However, stand-alone off-line game may not require internet connection but pro-longed use predisposes bored. Therefore, multiplayer on-line game meets the needs of groups of human activity. In the almost multiplayer on-line games,...
In this paper we propose the playback system for mashup based on mobile device in a sporting game. We designed the user experience for mobile environment: it was implemented so that a viewer can see the event segment video and the mashup information such as the additional information associated with it in the sporting game. Besides, it was also developed that a viewer can watch the main broadcasting...
After Great East Japan Earthquake, we increase importance to conserve electric power consumption by using Home Energy Management System, HEMS for short. However, HEMS is insufficient approaches other than change in figure. This study develops user experience as a service for consumers and estimates the system.
In this paper we propose a task based load distribution framework for Massively Multiplayer Online Games running in hybrid cloud environments. Our solution breaks down high level tasks into subtasks in such a way that i) core subtasks (those with strong timing constraints) are executed at private resources owned by game operators; while ii) background subtasks (those with looser timing/reliability...
Information Centric Networking (ICN) is a new kind of network architecture centered on content data. The ICN improves the efficiency of data transmission by the longest matching routing mechanism based on the content name prefix of the request interest packets, however, the multipath forwarding performance also resulted in the redundancy of the network content. The existing ICN forwarding strategy...
There are different theories to estimate cognitive abilities. Gardner proposed a model, where intelligence is defined by multiple fields instead of using one specific number. However, the characterization and automated evaluation of these fields are still open issues. If we can make standalone measurements in separate intelligence fields, the numerical modeling of the competencies is possible. Observing...
This study examines (also develops) several scenarios in a massively multiplayer online game, World of Tanks, in order to observe player's response to the occurred/created stimuli in different situations. A qualitative approach through observation and experience is employed to study the behavior of team players in the real situations, although occurring in a virtual environment. World of Tanks offers...
Cloud-based data storage is a popular cloud services. It can alleviate data management burden of data owner. However, after data file is transferred to the cloud, data owner is not able to physical dominate these outsourced data file. To efficiently ensure these data intact, several ReD-based integrity checking schemes were presented to ensure data integrity. Due to periodical checking, many data...
Push notification is a mechanism that allows individuals to receive updated information quickly. Push notification delivery needs to be effectived and has to be paid attention to time zone differences between countries in order to generate time-appropriate notifications. This push notification system was developed using distributed event-based system approach. The research methodology consists of...
Virtual machine migration represents a new topic of research last years. In this context, we present a new system based on matching game theory to design efficient and practical migration algorithms that work well with huge numbers of VMs and servers. This strategy solves VM migration, resources managements and load balancing problems in cloud computing environment. The experimental results show that...
Traffic congestion control is pivotal for intelligent transportation systems. Previous works optimize vehicle speed for different objectives such as minimizing fuel consumption and minimizing travel time. However, they overlook the possible congestion generation in the future (e.g., in 5mins), which may degrade the performance of achieving the objectives. In this paper, we propose a vehicle Trajectory...
Content Delivery Network (CDN) services largely affect the delivery quality perceived by users. While those services were initially offered by independent entities, some large ISP now develop their own CDN activities to control costs and delivery quality. But this new activity is also a new source of revenues for those vertically integrated ISP-CDNs, which can sell those services to content providers...
In this work, a serious game is presented to sensitize young people to stigma in mental health. This a video game, developed by a multidisciplinary team (computer scientists, psychologists, psychiatrists and educators), features characters that have different mental disorders. It provides different information about what mental illness is while the player interacts with the characters in different...
Game is one of the content services provided by an IPTV based on a Set-Top Box which is a terminal required for interactive multimedia communication at home. However, because IPTV service providers have an overall control of the Set-Top Box, game developers experience difficulty in fully testing the games before launching them. In this paper an IPTV game test-bed system is implemented based on Bluetooth...
