The recent advances in networking have determined an increasing use of information technology to support distributed cooperative applications. Several novel applications have emerged in this area, like computer supported collaborative work (CSCW), large scale distributed virtual worlds, collaborative recommender systems, collaborative learning systems. The definition of these applications requires to afford several challenges, like the definition of user interfaces, of coordination protocols, and of proper middle-ware and architectures supporting distributed cooperation. Collaborative applications may greatly benefits also from the support of P2P and cloud architectures. As a matter of fact, with the emergence of readily available P2P and cloud platforms, collaborative applications developers have the opportunity of deploying their collaborative application by exploiting a hybrid P2P/Cloud architectures with a support dynamically adapting . This brings possibilities to smaller developers that were reserved for the big companies until recently. The integration of mobile/Cloud platforms for Collaborative Applications is another challenge for the widespread of these applications.

Group Formation (GF) strongly influences the collaborative learning process in Computer-Supported Collaborative Learning (CSCL). Various factors affect GF that include personal characteristics, social, cultural, psychological, and cognitive diversity. Although different group formation methods aim to solve the group compatibility problem, an optimal solution for dynamic group formation is still not addressed. In addition, the research lacks to supplement collaborative group formation with a collaborative platform. In this study, the next level of collaboration in CSCL and Intelligent Tutoring System (ITS) platforms is achieved. First, initial groups are formed based on students learning styles, and knowledge level, i.e. for knowledge level, an activity-based dynamic group formation technique is proposed. In this activity, swapping of students takes place on each permutation based on their knowledge level. Second, the formed heterogeneous balanced groups are used to augment the collaborative learning system. For this purpose, a hybrid framework of Intelligent Tutor Collaborative Learning (ITSCL) is used that provides a unique and real-time collaborative learning platform. Third, an experiment is conducted to evaluate the significance of the proposed study. Inferential and descriptive statistics of Paired T-Tests are applied for comprehensive analysis of recorded observations. The statistical results show that the proposed ITSCL framework positively impacts student learning and results in higher learning gains.

In recent years cloud computing has taken off and has become an underlying technology in many online applications and websites, whether using a private or public cloud. At the same time with the increase in globalization, online collaborative tools have become very important in order to allow different businesses to communicate with each other, or even different parts of the same company to communicate more easily and share data. Previous work introduced an architecture for a geographically distributed, cloud based collaboration application. While the architecture allowed the scaling up and down of the number of cloud instances being used to host media servers, no control scheme for such cloud scaling was provided. In this paper a model and control scheme for cloud scaling for a collaboration application is provided. The model is based on the leaky bucket model commonly used in network control, while the control system is a self-organizing system. A testbed for the architecture is also presented and used in order to gather performance data from the collaborative application.

Human organizational patterns applied to collaborative learning software systems

The introduction of collaboration applications on the Internet has enriched communication between diverse users via chatting, and audio and video conferencing. It has also facilitated numerous real life tasks such as conducting of business meetings on the web, distance learning, and distributed authoring. Unfortunately, there are several difficulties that prevent collaboration applications from being ubiquitous on the Internet. The major difficulty is the lack of standards for communication between different collaboration applications which restricts collaboration to only instances of the same implementation, and in turn, limits the usability of such applications. In this paper, we propose a novel collaboration protocol for the exchange of information between users in collaborative environments. The proposed protocol is not tied to a specific implementation of collaboration tools which would enable several tools of the same type to communicate with each other independently of their implementation details. We also discuss a framework architecture for integration of several collaboration tools into one application. The proposed framework utilizes our proposed protocol, and adopts an HTTP-based communication model in order to overcome another difficulty which is possible firewalls constraints. In particular, we extend the standard HTTP streaming technology to accommodate several forms of collaboration.

The human-robot collaboration unites positive skills of humans (flexibility, intuition, creativity) and robots (strength, stamina, velocity, precision) in order to ensure a high level of resource efficiency and productivity also with smaller batch sizes and a high variety of versions in production. However, the design of a collaborative assembly system is a complex engineering challenge due to the different goal criteria that have to be considered. A simulation tool for designing and securing human-robot collaboration is yet missing which prevents the widespread use of such technologies. This paper proposes a concept of a simulation tool for collaborative workplaces. In the future, this will ensure that also companies with little experience and limited resources are empowered to implement human-robot collaboration systems prosperously.

And researching result shows that the internet based distance collaborative learning server could provide a good system support for those distance learners.

Computing in Large-Scale Dynamic Systems

Although collaboration tools have existed for a long time [8], Internet-based multimedia collaboration has recently received a lot of attention mainly due to easy accessibility of the Internet by ordinary users. The Java platform and programming language has also introduced yet another level of easy accessc platform-independent computing. As a result, it is very attractive to use Java to design multimedia collaboration systems for the Internet. Today there are many systems, which use Java for multimedia collaboration. However, most of these systems require the shared Java application to be re-written according to the collaboration system's Application Programming Interface (API)—a task which is sometimes difficult or even impossible. In this paper, we describe a practical approach for transparent collaboration with Java. Our approach is transparent in that the Java application can be shared as is with no modifications. The main idea behind our system is that user events occurring through the interactions with the application can be caught, distributed, and reconstructed, hence allowing Java applications to be shared transparently. Our architecture allows us to make the huge installed base of Java applications collaborative, without any modification to their original code. We also prove the feasibility of our architecture by implementation of the JASMINE1 prototype.

It aims to dive into the intricacies of designing robust and effective document collaboration software focusing on understanding the requirements of such a system, the working principle of collaborative text editing, software architecture, technology stack selection, and tooling that can sustain such a system. To examine the pros and cons of the proposed system, the paper will detail how collaborative text editing software can benefit from such an architecture regarding availability, elasticity, and scaling. The intricate nature of this system renders this paper a valuable resource for prospective investigations within the domain of dependable systems and distributed systems. This research first examines the requirements of a real-time collaboration system and the necessary core features. Then, it analyzes the design, the application structure, and the system organization while also considering key architectural requirements as the necessity of scaling, the usage of microservices, cross-service communications, and client–server communication. For the technology stack of the implementation, this research considers the alternatives at each layer, from client to server. Once these decisions are made, it follows system development while examining possible improvements for the issues previously encountered. To validate the architecture, a testing strategy is developed, to examine the key capabilities of the system, such as resource consumption and throughput. The conclusions review the combination of modern and conventional application development principles needed to address the challenges of conflict-free document replication, decoupled and stateless event-driven architecture, idempotency, and data consistency. This paper not only showcases the design and implementation process but also sets a foundation for future research and innovation in dependable systems, collaborative technologies, sustainable solutions, and distributed system architecture.

Consistency control is a critical issue in collaborative systems. Supporting flexible consistency control in particular matches the dynamic and situated needs of cooperative work. However, previous approaches generally provide only limited flexibility due to their static binding between shared data objects and consistency control protocols. We propose a component-based framework that allows for the runtime plug-n-play of consistency protocols in collaborative systems. We model data and protocols in a way such that they are cleanly separated and can be dynamically bound at run time to achieve flexible control. Data-protocol bindings can happen at the property, object, and workspace levels. The framework provides reusable services for implementing adaptable consistency control in a range of collaborative workspace applications.

Currently, there are a lot of e-learning and collaborative platforms to support distance and collaborative learning, however, all of them were designed without considering the network infrastructure below. Under these circumstances when the platform is installed and runs in a campus, sometimes it has very poor performance. This paper presents a network and data link layer infrastructure design that classifies and prioritizes the voice and video traffic in order to improve the performance of the collaborative system applications. This infrastructure has been designed taking in consideration a typical network of a university campus, so that in this way it can be implemented in any campus. After making the design we have made some tests in a laboratory network demonstrating that our design improves 70- 130% the performance of these real time collaborative systems which transmit voice and video.
