This demonstration illustrates PhotoNet, an image delivery service for mobile camera networks. PhotoNet is motivated by the needs of disaster-response applications, where a group of survivors and first responders may survey damage and send images to a rescue center in the absence of a functional communication infrastructure. The protocol runs on mobile devices, handling opportunistic forwarding (when...
The increasing popularity of GPS (Global Positioning System) device has boosted many applications, especially those for GPS information visualization. Information visualization techniques are invaluable tools in numerous applications. The goal of this work is to provide visual access to GPS information through the proposed trip planning web application. The main focus is on visualization, organization,...
M-GBCP is a new topic in the field of e-GBCP, and regarded as the application of wireless communication technology and computer technology in the public management, which provides public service for the public through mobile terminal and network technology. This paper examines provision of public service based on mobile communications technology.
One of the biggest shortcomings in the traditional mobile public information system is lack of a reasonable mechanism for data mining, which can not be reasonably classification of the publish information and scientific analysis of the public feedback information. In order to compensate for this shortfall, we describe a public service information and public feedback-based intelligent mobile public...
For wheelchair users and their care workers activities that are part of the daily fabric of life can be distressing. Taking a short trip to the local shopping center, post office or bus station can be filled with problems, obstacles that may not cause any hindrance to a pedestrian will cause problems or even hinder progress all together for a wheelchair user. The ubiquity of mobile phones coupled...
The following topics are dealt with: financial theory; stock markets; regression analysis; GARCH process; credit scoring model; linear programming; Granger causality; risk management; banking; investment; e-commerce; e-learning platforms; mobile technology; public sector governance; and medical services.
Information and Communications Technologies (ICT) plays an essential role in today's public administration. Countries, which are in the phase of recovering from conflicts and reinstating key functions of state administration, benefit from the utilization of ICT in order to offer services more quickly and efficiently to their citizens. This case study describes and discusses an ICT based solution Crisis...
The paper reports a study on the implications of virtualized working structures for employee self-determination and organizationally beneficial outcomes. Structural equation modeling was used to analyze survey data of N = 1009 employees in a German public administration. Mobile telecommuting was associated with higher levels of task-related autonomy, whereas home-based telecommuting predominantly...
This paper forms part of a series of investigations into the key success factors for mobile government services (mGovernment) in Australia, Jordan and the United Arab Republic. The case study in this paper concerns a large city council in Queensland, Australia and provides valuable insights into the adoption of mobile government services. A table of success factors, that should prove useful to other...
E-government is the use of information technology to enhance access to and delivery of government information and services to the public for effectiveness, efficiency and quality government operations. An effective e-Government service depends on a clear vision, mission and strategy to facilitate service delivery in all parts of the country especially in the rural areas where infrastructure is a challenge...
Mobile E-Government is a new E-Government application model developed based on the traditional E-Government. Through the construction of mobile E-Government, the governments of Wuhan urban circle can fully break through the limits of time and space and provide convenient and highly efficient public services to the city clusters within a circle whose radius is 100 km. This paper, through a study on...
This paper studies mobile devices mediated electronic voting system based on the distributed Pailler's encryptions; We apply the standard cut-of-the-choose technique to avoid the computational zero-knowledge proofs and show that the proposed scheme is efficient yet somewhat provably secure in the simulation-based paradigm.
With the development of mobile communication technologies (MCT), non-tech factors show more significant impacts in the process of innovation diffusion and service utilization in the ubiquitous network society. To analyse the individual acceptance of mobile communication technology (MCT) from the cultural perspective, a novel model is proposed based on Hofstedepsilas theoretical framework. In this...
In this paper, we explore the feasibility of using Mobile Ad-hoc Networks (MANETs) for rural public safety. First, we discuss a QoS enhancement to a standard routing protocol, Dynamic Source Routing (DSR). By incorporating a new routing metric and the available bandwidth and delay estimation algorithms with DSR, we design a new routing protocol, QoS- Aware Source Routing (QASR), to meet the QoS requirements...
Assistive technology so far has been focusing on promoting greater independence for people with disabilities by enabling them to perform tasks on a personal basis. Assistive technology that leverages networks of caregivers, who may be nomadic or even remain on the go constantly, has not been developed into useful services or even explored systematically. In this paper, we first propose a general architecture...
Based on the current situation in rural China, the present paper analyzes several mobile communication approaches to the realization of informatization in these areas, which include "rural information service", "rural information device", "rural supply & marketing service", "rural government affairs service" and "agricultural wireless monitoring system"...
This paper focuses on the explanatory value of context parameters and individual characteristics for preferences of police officers for mobile applications. Starting from adoption and acceptance (DoI and TAM), media choice and task-technology fit (TTF) theories, we collected data from police officers, who were asked which specific communication devices they preferred in specific situations. Our analyses...
Datacasting involves the use of the excess bandwidth in a digital terrestrial television station's stream to deliver broadcasted data to a variety of receivers. Initially developed as a stationary fixed technology, this project involves receiving this broadcast in a mobile environment. This one-way transmission allows the datacast receiver to decouple data packets at a rate of up to 2.5 Mbps. Utilizing...
Communities of need face many health crises and often rely on our public health system or their community-based organizations for help in lieu of medical practitioners or clinics. These same communities also turn to affordable cell phones in lieu of landlines for mobility, and cost savings. Public health practitioners and community practitioners who provide local services find ongoing communication...
This paper presents a service-oriented model and architecture for security in multichannel information systems of public administration, where services can be delivered to citizens and enterprises on various channels, including mobile systems. The model and architecture are based on the definition of service delivery channels given in some ongoing e-government projects. In particular, the security...
