“…In [9] the authors suggest to combine P2P networks, Grid and e-Learning together aiming for business, academic and individual use to enable e-Learning environment to be more powerful, efficient, scalable, mobile and versatile. To this end, they propose a powerful system by modifying the Gnutella protocols that can broadcast the live class on a P2P network and offer more accesses to users than the traditional client-server paradigm.…”

Efficient peerGroup management in JXTA-Overlay P2P system for developing groupware tools

et al. 2009

With the fast development of IT technologies, virtual organizations are more and more present in the current collaborative work and learning activity. For instance, many subjects in virtual distance learning are organized as online groups of students, who use groupware tools to complete their learning tasks. In this paper, we address the efficient management of peer groups in JXTA-based P2P systems as a key issue in many P2P applications that use peer group as a unit such as for remote execution of tasks in parallel and distributed applications. From this perspective, we consider peer grouping as the basis in the development of groupware tools in P2P systems.Motivated by the need to support online teams of real virtual campuses, in this work we propose the management of peer groups in JXTA-Overlay, a JXTA-based P2P middleware for the development of P2P applications. To this end, by taking advantage of the peerGroup entity in JXTA library we have designed and implemented a set of primitives as part of JXTA-Overlay aiming to support efficient peer group 46 F. Xhafa et al. management. We show the usefulness of using JXTA-Overlay for the development of P2P groupware tools for supporting online teams of students in a virtual campus. Our approach distinguishes from existing studies by using groupware tools in a customized way and tailored to the specific needs of small online teams of students who consider group monitoring and autonomy, confidentiality and security as important concerns.The groupware tools developed for P2P systems include instant messaging and chat rooms, task execution in peer group's resources and file sharing system. We successfully deployed these tools based on JXTA-Overlay in a real P2P network. The experimental results showed the feasibility of our approach when applied to small groups of students who use standard desktop and laptop computers and have rather limited bandwidth of Home Net connections. On the other hand, the JXTA library showed some performance limitations, such as CPU consumption, when using the P2P file sharing system and sharing about three hundred files among all peers of a real small network made up of limited computational resources and rather small bandwidth.

“…For example, Jin et al [14] described a peer-to-peer based learning environment over the Internet, named APPLE, which has a combination of P2P overlay network, Internet broadcast system, and grid technology, and reported satisfactory results in educational experiments with general computers. Compared to this research work, our system is much simpler and does not require any burden of P2P routing algorithms, due to the dominant feature of UPnP protocol stack and service-oriented architecture involved.…”

Abstract-Although Universal Plug and Play (UPnP) network is aimed basically at home/ office service automation for general purposes, it can turn out to support for ubiquitous learning objective as well, if somewhat level of semantic capability will be involved. In this paper, we discuss how the UPnP network infrastructure should be polished with the Linked Data principle for enabling semantic-based ubiquitous learning services so that sharing digital contents can be done between heterogeneous devices in an effective manner, without the need of many distinct learning standards. In addition, we describe a case of simple quiz to illustrate how the Linked Data publishing of distributed multimedia resources can be utilized in our extended UPnP architecture.Index Terms-Linked data, semantic web, ubiquitous mobile learning, UPnP. I. INTRODUCTIONSmart home network technology has provided excellent opportunities for people to experience both local services in home/office automation and public services from the Internet accesses to premises. However, for the educational purposes, smart home network is often used to facilitate for the remote access of e-learning facility, but it is rarely utilized to provide for group-based learning among computers or mobile devices at homes or enterprises. This is crucially due to the lack of adequate systems and tools, which are indeed necessary for the arrangement of ubiquitous and mobile learning inside or outside premises.Although a number of mobile learning systems have been researched to date (see [1] and Refs therein), they do not take advantages of existing ubiquitous network infrastructures designed for smart home into consideration. Therefore, their architectures are complex inevitably, due to the necessity for handling many basic (but crucial) issues, such as associating heterogeneous devices, discovering devices nearby, or enabling collaborative learning operations on a peer-to-peer (P2P) basis. We argue that the complexity of these architectures can be lessened by involving the support of pervasive network infrastructure, such as Universal Plug and Play (UPnP) [2], which is targeted for smart home/office service automation.In addition, we encourage the exploitation of web-related technologies for many reasons. For instance, they are the technologies that are founded in the UPnP infrastructure for handling the problem of platform heterogeneity.

“…The SeLeNe system [11] proposed a P2P network to support distributed learners in sharing learning resources in a peer community; and it envisaged using ECA rules to provide the change propagation and notification services required by such learners. P2P technologies may also be useful for enabling eLearning environments to be more efficient, scalable, mobile and versatile [7], [9], for supporting group cognition processes in problem-solving environments [6] and for enabling integration with the new paradigm of personal knowledge management [2].…”

Abstract-One of the major premises of P2P systems is to enable fully decentralized collaborative functionalities for supporting work teams and P2P communities. Within collaborative systems, tracking and awareness are vital aspects for a successful collaboration. Despite the experience of using awareness in webbased applications, there has been little research in endowing P2P collaborative systems with generic, application-independent awareness mechanisms to fully support collaboration.In this work we present a distributed event-based awareness approach for P2P groupware systems. Unlike centralized approaches, several issues arise and need to be addressed for awareness in P2P groupware systems, due to their large-scale, dynamic and heterogenous nature. In our approach, the awareness of collaboration will be achieved by using primitive operations and services that are integrated into the P2P middleware. As a first step, we identify the major requirements for such an event-based awareness approach, including dynamics of events, genericity of events, lightweight mechanisms, automation via the use of rules, as well as event transformation, presentation, propagation and notification services in order to fully support timely awareness of collaboration activity. We then propose an abstract model for achieving these requirements and we discuss how this model can support awareness of collaboration in mobile teams.
