Advanced mobile devices such as smartphones have become a part of daily lives for digital native students today. We believe that the integration of mobile computing into computer science (CS) curricula with smart mobile devices based learning tools will connect the education to leading-edge information technologies, motivate and engage students in CS learning, innovate CS education, fill in the gap...
Vehicular Ad hoc Networks(VANETs) enable plenty of important applications for vehicles, such as accident prevention and traffic jam avoidance. However, VANETs can hardly provide reliable connectivity between vehicles, which makes data dissemination of the aforementioned applications extremely difficult. Compared with VANETs, 3GPP cellular networks(e.g., LTE), offer much more reliable connectivity...
When adapting existing table games for the mobile setting, there is a choice of either keeping the round-based approach of such games or giving it up and optionally replacing it with additional “magical” features only available for the location-based version of the game. Based on our experience in building a hide and seek game using both approaches independently in two research groups, we compare...
There is an increasing visibility of mobile social games in Japan. The radical growth of item-purchasing in mobile social games is generating new hype in mobile business. The author revisits the game and social factors of the revenue-generating engines of mobile social games. The author examines the underlying principles of revenue-generating engines in mobile social games, which leads to exploration...
Today's mobile learning application development does not only require a sophisticated pedagogical design, but also faces a number of technical challenges to overcome several problems and limitations. In this paper, we present common challenges in scaling mobile learning applications for real world environments and exemplify our solutions and decisions for the collaborative and context-aware quiz playing...
In this paper we present results of traffic modeling and simulation of multiplayer real-time games and M2M applications using TCP protocol over Telekom Serbia HSPA mobile network, performed within the FP7 LOLA project. In this experimentation, the RTT (Round Trip Time) and cell statistics are analysed. For this purpose, a traffic generation application is developed for Android phones to generate traffic...
In this work, we explore how information services can be used to improve the travel experience in public transportation and reduce the perceived travel time. More specifically, we describe the creation of a mobile application for assisting passengers, which explores the integration of social networking features into the traveling experience. The overall objective is to understand how social networking...
Gaming market is gaining rapid significance and recognized as one of the most revenue generating futuristic services. With IMS(IP Multimedia Subsystem) networks coming in to reality a new gaming experience can be provided to the subscribers by blending the gaming service with IMS service enablers such as presence, location etc. An intelligent service broker element like Service Capability Interaction...
Mobile infostation networks which achieve content distribution by exploiting the opportunistic contact among mobile users (MUs) and access points (APs) have attracted a lot of attention in the last few years. It is found that cooperation either between APs or MUs has a great impact on the network performance. However, in most of the existing works wherever cooperation is involved, cooperation among...
Growth of network access technologies in the mobile environment has raised several new issues due to the interference between the available accesses. Thanks to the currently used access methods such as OFDMA in mobile networks, and LTE systems, the intra-cell interferences are avoided and the quality of service has increased. Nevertheless, the diversity and multiplicity of base stations in the network...
The mobile Internet business is entering a new era in Japan with the emerging revenue being generated from mobile social games. Users using high-speed mobile Internet with flat-rate data services have acceptance of micro-payments and increased payment acceptance in mobile social games. This has been impacting mobile business and the game business in Japan for the last 12 months. Given the hype surrounding...
For cost effective deployment and implementation, mobility is introduced in sensor networks to provide dynamic event coverage. A hybrid network of static and mobile nodes, can yield the same desired accuracy and robustness of a static k-coverage detection model with fewer nodes. Since node movement is a costly operation and the movement strategy has to be decided instantly after event occurrence,...
This work centers on data dissemination in delay-tolerant mobile networks, where data fall into a range of interest types and each node may have one or multiple interests. The goal is to deliver data messages from sources to nodes with corresponding interests. We consider selfish nodes with rational behavior, and propose a credit-based incentive scheme to promote nodal collaboration. The key challenge...
The recent developments of smart mobile phones and 3G networks enable users to enjoy video programs by subscribing to data plans. Due to phone-to-phone communication technologies and ubiquity of mobile phones, data-plan subscribers are able to redistribute the video content to non-subscribers. Such a redistribution mechanism is a potential competitor for the mobile service provider and is very difficult...
Mobile social applications are becoming increasingly popular with a growing number of users turning to mobile devices for socializing, information sharing, retrieval or related activities, and/or gaming. The increased interest in the domain has resulted in numerous application prototypes being reported in the recent years that combine elements of socializing, gaming, and information related activities,...
Mobile social applications are becoming increasingly popular with a growing number of users turning to their mobile devices for socializing, information sharing and/or gaming. The increased interest in the domain has resulted in numerous mobile social application prototypes being reported in the recent years, each combining interesting elements of socializing, sharing and gaming with varying abilities...
We describe a multi-agent based context-aware mobile educational game that can generate a series of learning activities for users doing on-the-job training in their working environment. In this paper, we reveal the multi-agent architecture (MAA) that is designed in the mobile educational game. The multi-agent architecture design enables development of a lightweight, flexible, and scalable game on...
This paper made a detailed analysis on the characteristics of mobile online games and pointed that security is one of the most important things which the games operators should focus on. There are several fields of the security problems, the communicate security would be the most important one. In the authors' opinion, the communicate security could be effectively improved through crypto system, then...
Mobile social networks have been introduced as a new efficient (i.e., minimizing bandwidth usage) and effective (i.e., minimizing the delay or maximizing the number of target recipients) way of disseminating content and information to a particular group of mobile users who share similar interests. In this paper, we investigate how the content providers and the network operator can interact to distribute...
The rapidly growing bandwidth demand for mobile internet and mobile broadband applications is currently triggering the development of novel approaches to increase the capacity of the macro infrastructure of current mobile networks. Among the available options, increasing the spatial density of mobile sites is of specific interest, while at the same time the resulting new paradigm of user-provided...
