Abstract: Smart Mobile Devices (SMD) are there for many years but using them as learning tools started to emerge as new research area. The trend to merge collaborative learning methodology by using mobile devices in informal context is important for implementation of Learner Centric Learning (LCL). Survey and numerous studies show that more than 95% of students in colleges are users of these smart mobile devices in developed world. Developing counties are also catching up and we can see this percentage is almost same in university level in these countries. Students are using SMDs for learning in some form. Higher education Institutions also try to embark their E-learning to Mobile learning (ML). The aim of this paper is to do propose operational framework for designing Mobile Collaborative Informal learning activities using SMDs. Show results of experimental and case study done to study the Mobile Collaborative Informal learning using Activity Theory (AT). Core Components of framework are Mobile Learning Activities/Objects, Wireless/Mobile Smart devices, Collaborative knowledge and Collaborative learning. The research mention here is its infancy stage.
An Agent-based Architecture for Developing E-learning System  [PDF]
Hasan Al-Sakran
Information Technology Journal , 2006,
Abstract: From the perspective of e-learning view, it is important to deliver dynamic learning content and manage educational material in an efficient way. An e-learning system should present personalized optimal content to the user, anytime and anywhere and encourage collaborative learning. It should guide specific individuals to their most relevant community or communities of knowledge by exploring the materials that others in the community are viewing or reading and linking learners and with experts. The purpose of this study is to formulate a functional architecture that supports the above e-learning objectives using mobile agent technology. This architecture gives users the ability to collect, analyze, distribute and use e-learning knowledge from multiple knowledge sources. The mobile agent technology is particularly suitable for developing distributed e-learning systems because it supports intelligent and distributed storage, allows an optimal personalized e-learning environment and enhances modularity, reusability, flexibility and reliability.

Computer Science , 2014,
Abstract: Mobile smartphones along with embedded sensors have become an efficient enabler for various mobile applications including opportunistic sensing. The hi-tech advances in smartphones are opening up a world of possibilities. This paper proposes a mobile collaborative platform called MOSDEN that enables and supports opportunistic sensing at run time. MOSDEN captures and shares sensor data across multiple apps, smartphones and users. MOSDEN supports the emerging trend of separating sensors from application-specific processing, storing and sharing. MOSDEN promotes reuse and re-purposing of sensor data hence reducing the efforts in developing novel opportunistic sensing applications. MOSDEN has been implemented on Android-based smartphones and tablets. Experimental evaluations validate the scalability and energy efficiency of MOSDEN and its suitability towards real world applications. The results of evaluation and lessons learned are presented and discussed in this paper.

Computer Science , 2013,
Abstract: Mobile collaborative learning (MCL) is extensively recognized field all over the world. It demonstrates the cerebral approach combining the several technology to handle the problem of learning. MCL motivates the social and educational activities for creating healthier environment. To advance and promote the baseline of MCL, different frameworks have been introduced for MCL. From other side, there is no highly acceptable security mechanism has been implemented to protect MCL environment. This paper introduces the issue of rogue DHCP server, which highly affects the performance of users who communicate with each other through MCL. The rogue DHCP is unofficial server that gives incorrect IP address to user in order to use the legal sources of different servers by sniffing the traffic. The contribution focuses to maintain the privacy of users and enhances the confidentiality. The paper introduces multi-frame signature-cum anomaly-based intrusion detection systems (MSAIDS) supported with innovative algorithms, modification in the existing rules of IDS and use of mathematical model. The major objectives of research are to identify the malicious attacks created by rogue DHCP server. This innovative mechanism emphasizes the security for users in order to communicate freely. It also protects network from illegitimate involvement of intruders. Finally, the paper validates the mechanism using three types of simulations: testbed, discrete simulation in C++ and ns2. On the basis of findings, the efficiency of proposed mechanism has been compared with other well-known techniques.

The Turkish Online Journal of Distance Education , 2007,
Abstract: This paper provides an overview on the current state of art in the field of Distance learning for mobile users. It mentions a large range of technologies, services and approaches that may be used to bring distance learning to mobile internet users. These technologies are supposed to considerably increase innovative e-learning solutions for the next generation. While this definitely appears to be true, I think what is not so clear are the implications for students, and lecturers etc. In this article I first evaluate distributed e-learning technologies. With some of the most vital topics, focusing on adaptive distributed e-learning for Mobile Internet Users (MIUs). I also provide a brief analysis of Broadband Network Services, Collaborative e-Learning Tools and Distributed Virtual Environments, Internet-Based Adaptive Learning Technologies and Personalised Distance Learning. I continue my discussion on to Internet Development Tools (IDTs) for Distance Learning Solutions, Learning Technologies for MIUs, Semantic and Web-Based Services for Enriching Learning Interactivity, and Evaluations of Distributed Learning Technologies (DLTs).
A Survey of Routing Techniques for Mobile Collaborative Virtual Environment Applications  [PDF]
Anis Zarrad
International Journal of Computer Science Issues , 2012,
Abstract: Due to the rapidly increasing usage of personal mobile devices and the need of executing CVE applications in environments that have no previous network infrastructure, Mobile Collaborative Virtual Environments (MCVEs) systems will become ubiquitous in the future. In such systems, we enable users to act and interact in three dimensional world shared through their mobile devices in an ad-hoc network (MANET). A handful of interesting MCVE applications have been developed in a variety of domains, ranging from multiplayer games to virtual cities, virtual shopping malls, and various training simulations (i.e. military, emergency preparedness, Education, Medicine, etc.). The designers of such applications rely solely on network overhead, latency, limited bandwidth, and mobile device limitation. In this survey we present a number of ways to classify and analysis routing techniques that have been applied in Mobile Collaborative Environment Applications.

International Journal of Interactive Mobile Technologies (iJIM) , 2009, DOI: 10.3991/ijim.v3i4.905
Abstract: - The use of mobile devices for delivering learning tools is an attractive concept. Termed mobile learning (m-learning), this new technology allows people to participate in learning activities without being tied to a fixed location and provides users with convenient and flexible access to learning resources anytime and anywhere. While many m-learning applications have been developed to date, most provide tools to help students’ with specific learning tasks rather than a general interface to online courses. Few sup-port online learning communities or allow users to download multimedia learning content. These features would engage mobile users and enable them to interact with one another, thus allowing them to participate in group learning activities despite their changing location. In this article, we describe an m-learning system which we have developed which aims to incorporate these facilities. This system provides access to multimedia learning resources and supports mobile users in an interactive synchronous learning environment with their desktop peers. Details of the evaluation techniques which we utilised to appraise the system are provided and the results are presented. Feedback suggests that the features offered by our system are beneficial for collaborative m-learning.

Abstract: Mobile collaborative learning (MCL) is highly acknowledged and focusing paradigm in eductional institutions and several organizations across the world. It exhibits intellectual synergy of various combined minds to handle the problem and stimulate the social activity of mutual understanding. To improve and foster the baseline of MCL, several supporting architectures, frameworks including number of the mobile applications have been introduced. Limited research was reported that particularly focuses to enhance the security of those pardigms and provide secure MCL to users. The paper handles the issue of rogue DHCP server that affects and disrupts the network resources during the MCL. The rogue DHCP is unauthorized server that releases the incorrect IP address to users and sniffs the traffic illegally. The contribution specially provides the privacy to users and enhances the security aspects of mobile supported collaborative framework (MSCF). The paper introduces multi-frame signature-cum anomaly-based intrusion detection systems (MSAIDS) supported with novel algorithms through addition of new rules in IDS and mathematcal model. The major target of contribution is to detect the malicious attacks and blocks the illegal activities of rogue DHCP server. This innovative security mechanism reinforces the confidence of users, protects network from illicit intervention and restore the privacy of users. Finally, the paper validates the idea through simulation and compares the findings with other existing techniques.
