Technological advances in three basic fields mobile devices, communication, services architecture have helped the vertiginous evolution of mobile GI services. Mobile computing scenario, which take into account the relative position of users, service components, and available resources, encourages the development and deployment of innovation services. As for Mobile GI Services application, the driving...
This paper develops a client-side context-aware search application which is built on the context-aware infrastructure. A context-aware architecture is designed to collect the mobile user's context information, derive mobile user's current context, distribute user context among context-aware applications, and support the context-aware applications. The context acquisition is centralized at the context...
In this paper, we introduce an m-commerce security architecture; discuss how the communication takes place between user, mobile station (MS) and access point (AP). We use an new authenticated mechanism between user and MS. And we add Access Point in wireless net in order to avoid being attack and eavesdropping message. We analyze the characters of the architecture with the Summary of Mobile E-commerce...
Context-aware computing is one of the research fields of pervasive computing. Context-aware systems can react to the user's preference according to the circumstances called context including location, time and other environment conditions. Many context-aware computing paradigms were developed in recent year, however, it is difficult for the present systems to extend the application domains and interoperate...
Health care systems will integrate new computing paradigms in the coming years. Context awareness computing is a research field which often refers to health care as an interesting and rich area of application. One of the areas for context aware computing is social awareness amongst a group of individuals. Providing individuals with social awareness about other coworkers is very important in order...
Several mobile guides exist providing tourists with location-based content delivery. This paper presents a novel mobile application, named InfoTour, aiming at enriching touristspsila experiences by supporting social interactions among tourists and by enabling seamless interaction with third-party service and data providers. The proposed system is based on service oriented architecture principles,...
With the emergence of pervasive computing environments, mobile information sharing and retrieval is becoming an exciting domain that challenges information scientists. In this paper, we describe a hybrid peer to peer context-aware framework for building mobile information sharing applications. A scalable and flexible architecture based on JXTA is presented. The architecture called "JHPeer"...
Modern environments have huge quantities of contextual information that is mainly relevant/useful when a user/mobile is situated at particular locations. This paper investigates organizations for exchanging localized context and surveilling the corresponding areas that minimize bandwidth/energy requirements. We propose a simple model where context is associated with spatial regions, cells, and is...
Emerging rich wireless networking modalities facilitate the development of new intelligent, innovative services on smart phones. The authors propose a ubiquitous phone (UbiPhone) system that demonstrates innovative context-aware human-centric phone services, which could become available on smart phones. UbiPhone's features include UbiCall, AnyCall, and an emergency contact service.
Mobile and pervasive computing is gaining significant importance in the latest years. Context-awareness constitutes an essential aspect - almost a requirement - of mobile services in these environments. In this paper, we propose an architecture that supports the development and provision of context-aware services. The described approach provides means for the context adaptation of software components...
The emergence of new technologies and the proliferation of mobile and handheld devices have facilitated development of context-based services. Common examples include the location based services. However, the revelation of the context and static information gives rise to new and very complex privacy concerns in such services. In this paper, we propose a formal model to regulate the privacy level of...
With the growing number of services made available, through next generation networks, it is important that end-users have easy access to the right services at the right time. This paper explores a way by which this may be achieved, namely, the recommendation of services to the end-user at an opportune time. Presented is an architecture for the recommendation of services. A possible deployment with...
