Mobile support in CSCW applications and groupware development frameworks
Computer Supported Cooperative Work (CSCW) is an established subset of the field of Human Computer Interaction that deals with the how people use computing technology to enhance group interaction and collaboration. Mobile CSCW has emerged as a result of the progression from personal desktop computing to the mobile device platforms that are ubiquitous today.
CSCW aims to not only connect people and facilitate communication through using computers; it aims to provide conceptual models coupled with technology to manage, mediate, and assist collaborative processes. Mobile CSCW research looks to fulfil these aims through the adoption of mobile technology and consideration for the mobile user. Facilitating collaboration using mobile devices brings new challenges. Some of these challenges are inherent to the nature of the device hardware, while others focus on the understanding of how to engineer software to maximize effectiveness for the end-users. This paper reviews seminal and state-of-the-art cooperative software applications and development frameworks, and their support for mobile devices
Facilitating Mobile Music Sharing and Social Interaction with Push!Music
Push!Music is a novel mobile music listening and
sharing system, where users automatically receive
songs that have autonomously recommended
themselves from nearby players depending on similar
listening behaviour and music history. Push!Music
also enables users to wirelessly send songs between
each other as personal recommendations. We
conducted a two-week preliminary user study of
Push!Music, where a group of five friends used the
application in their everyday life. We learned for
example that the shared music in Push!Music became
a start for social interaction and that received songs in
general were highly appreciated and could be looked
upon as âtreatsâ

Mobile language learning now and in the future
The widespread ownership of mobile devices such as cellphones, personal media players, personal digital assistants (PDAs), smartphones and wireless laptops means that âmobile learningâ is no longer in the preserve of technical experts and researchers with specialist knowledge. Teachers and learners have begun to integrate mobile technologies into everyday practices and there is evidence of efforts to invent exciting new scenarios of use. Language learning is one of the disciplines that looks set to benefit from these developments. Learners can make good use of the facilities to record and to listen to audio at any time, supported by the rising availability of podcasts and the âalways onâ characteristics of portable devices which encourage spontaneous interactions. Mobile learning promises to deliver closer integration of language learning with everyday communication needs and cultural experiences
Resource Aware Application for Mobile Device In An Ad Hoc Wireless Network Environment
Ad hoc wireless networks can be applied in a collaborative computing in which the requirements of a temporary communication infrastructure for quick communication with minimal configuration between a group of people in a conference or gathering. The main purpose of this research is to develop an application that allows mobile nodes in a collaborative environment to share files among nodes. For this project, the application will be implemented on nodes in an ad hoc wireless network that have a strong incentive to collaborate and share resources. This paper presents the results of our preliminary study which are based on the previous research. It is divided into five sections where in the first section is an introduction of ad-hoc wireless network, then in the next section is regarding motivation of doing research in this area. In section four and five, the paragraphs focused on the evaluation for Mobile Ad Hoc Networking and related works respectively
Ad-Hoc Sharing for Palm Devices
The current generation of Palm PDA devices is designed to share information records primarily with a base desktop system, or a server. Therefore, their built- in features for sharing data during ad-hoc collaboration among groups of mobile users are inadequate. In this thesis, we describe a new framework that addresses this problem by allowing users to transparently share the record databases of common applications during spontaneous collaborative sessions. The framework also allows users to define custom sharing policies for each application/user pair. These policies determine the manner in which records are exchanged and update, thereby automating the process of handling conflicts and preserving user privacy preferences. We also present implementation results, in which we have used the framework to create shared versions of common applications, such as Calendar and Memo. Our experimental results show that the programming effort involved is minimal and the user interaction with the application is, essentially, the same as in the original application
Quality management of surveillance multimedia streams via federated SDN controllers in Fiwi-iot integrated deployment environments
Traditionally, hybrid optical-wireless networks (Fiber-Wireless - FiWi domain) and last-mile Internet of Things edge networks (Edge IoT domain) have been considered independently, with no synergic management solutions. On the one hand, FiWi has primarily focused on high-bandwidth and low-latency access to cellular-equipped nodes. On the other hand, Edge IoT has mainly aimed at effective dispatching of sensor/actuator data among (possibly opportunistic) nodes, by using direct peer-to-peer and base station (BS)-assisted Internet communications. The paper originally proposes a model and an architecture that loosely federate FiWi and Edge IoT domains based on the interaction of FiWi and Edge IoT software defined networking controllers: The primary idea is that our federated controllers can seldom exchange monitoring data and control hints the one with the other, thus mutually enhancing their capability of end-to-end quality-aware packet management. To show the applicability and the effectiveness of the approach, our original proposal is applied to the notable example of multimedia stream provisioning from surveillance cameras deployed in the Edge IoT domain to both an infrastructure-side server and spontaneously interconnected mobile smartphones; our solution is able to tune the BS behavior of the FiWi domain and to reroute/prioritize traffic in the Edge IoT domain, with the final goal to reduce latency. In addition, the reported application case shows the capability of our solution of joint and coordinated exploitation of resources in FiWi and Edge IoT domains, with performance results that highlight its benefits in terms of efficiency and responsiveness
