Ultra-dense network (UDN) is becoming significant with the rapid growth of smart terminals and traffic demands of the mobile network. In UDN, the number of small BSs is much more than that in the legacy network to satisfy the traffic demands from dense users. It is not suitable in UDN that a user is served by only one small BS. The prior research concentrated on coordinated multipoint transmissions...
Although the computational power of mobile devices has been increasing, it is still not enough for some classes of applications. In the present, these applications delegate the computing power burden on servers located on the Internet. This model assumes an always-on Internet connectivity and implies a non-negligible latency. The thesis addresses the challenges and contributions posed to the application...
4G communication systems provide a global communication standard for each and every communication facilities and internet and telecommunication service providers of the globe. The major attraction of 4G is the network selection policy which enables users to select services offered by the best of the various service providers. The main purpose of this paper is to discuss network selection in 4G systems...
Recently, mobile object sharing systems including car-sharing systems have been gathering more attention as an ecological activity. In this paper, we propose a user-collaborative mobile object assignment system using location information of users. The optimal mobile object assignment is to minimize travel distances of mobile objects in the existing mobile object assignment system, and the system controls...
Starting from the global manufacturing support in order to create workshops for the study, Human-machine cooperation is discussed about digital manufacturing workshop of the theoretical model. Wireless network communication technology in the digital manufacturing plant application is probed. Application of Mobile Intelligent Technology and digital technology are studied on the shopfloor involved in...
Learning ecological science content and inquiry strategies should increasingly use the new tools from science - sensors for data capture, information visualization for data-analysis, low-cost mobile computers and mobiles for field-based science. The LET's GO! project seeks to develop, implement, research, and sustainably scale a new paradigm for fostering high school student learning in teams for...
Distributed and mobile collaboration technologies continue to play an important role in supporting complex, flexible and interconnected collaborations within networked enterprises and e-science. The latest trends in distributed and mobile collaboration technologies allow people to work across organizational boundaries, to collaborate among/in organizations and communities and to be part of the collaborative...
We introduce MobiTOP (mobile tagging of objects and people), a map-based application which allows users to contribute and share geo-referenced multimedia annotations via mobile devices. An important feature of MobiTOP is that annotations are hierarchical, allowing annotations to be annotated to an arbitrary depth. MobiTOPpsilas interface was designed using a participatory design methodology to ensure...
The sixth "Agent-based Computing for Enterprise Collaboration" workshop at WETICE 2008 focused on the areas of: agent-based semantic composition of Web services; agent-oriented software engineering methodologies and tools; and large scale multi-agent systems. The intention of this workshop was to bring together researches in the fields of software agents as they relate to the context of...
Recent distributed and mobile collaboration technologies enable people to work in nomadic, dynamic teams. In these teams, team-members frequently join and leave the team, change their geographic location, or invite external experts to contribute their expertise. Therefore, the ability to query the company's distributed knowledge base and the search for experts in a specific domain even across enterprise...
