A hospital's mobile nursing cart can collect clinical data via Wi-Fi networks and save data in the server side. This service not only provides better medical care, but also enhances staff productivity. However, the coverage of Wi-Fi is limited and signal dead ends will result in wireless disconnection. This problem can be solved by switching between Wi-Fi and 3G. The physical connection must be disconnected...
This paper presents an efficient sharing protocol (iShare) that blends different wireless interfaces of the mobile device for content dissemination service. With iShare, mobile users download content from a source via the cellular link and at the same time form an ad hoc mesh network for peer-to-peer exchange of content data. The mesh remains robust to network dynamics, minimizes ad hoc communication...
In the idea of the Sensor Web, sensors should be discoverable, accessible and taskable over the internet. In this paper, we present a mobile data collection framework for connecting wireless sensors with the Sensor Web by using mobile devices. The proposed system is an extension to Locawe platform including now mapping and WSN features together with features of SWE especially Sensor Observation Service...
We propose a privacy conserving protocol to share location information with groups of trusted agents (e.g. friends) using a mobile device. All information published by the user is cryptographically secured and authenticated. Furthermore, we employ methods to make it hard for third parties to derive a user's relationships from communication patterns. Users can create multicast groups spontaneously...
Mobility has become a keyword nowadays with the evolution of mobile devices market and proliferation of real-time services. IP Multimedia Subsystem (IMS) is a single, standardized service framework that supports voice, video, data and messaging services, but does not provide seamless mobility for packet based sessions. This paper purposes an IMS architecture with IEEE 802.21 and media-independent...
With the rapid development of mobile networks technology and popularization of mobile device, people can access Internet by mobile device and wireless connection covering the entire mobile communication network (GSM/GPRS/CDMA/3G/802.11etc) at any moment. Business system based on mobile network has been becoming hotspot. Compare with traditional business system, the security risk of business system...
Researches in mobile commerce have increased significantly with the emphasis on identifying new applications, designing frameworks, and engineering network solutions. Mobile payment is a natural successor to Web centric payments which has emerged as one of the sub domains of mobile commerce applications. A study reveals that there are wide ranges of mobile payment solutions and models which are available...
A mobile service covers a large field of technologies ranging from the mobile device such as a PDA or a phone to the enterprise content server through all the wired and wireless networks between them. In this paper, the focus is given to the client side application, the associated technologies and chosen frameworks to built these kind of contents. Some samples of technologies will be presented ranging...
