Peer‐to‐Peer computing offers many attractive features, such as collaboration, self‐organization, load balancing, availability, fault tolerance and anonymity. However, it also faces many serious challenges. In our previous work, we implemented a synchronous P2P collaboration platform called TOMSCOP. However, the TOMSCOP was implemented only in Windows XPOS. In this work, we extend our previous work and present a multi‐platform Peer‐to‐Peer system. The proposed system operates very smoothly in UNIX Solaris 9 OS, Linux Suse 9.1 OS, Mac OSX, and Windows XP. In this paper, we present the design of proposed system and four web application tools: info, joint draw pad, shared web browser and subaru avatar.

Satellite networking will be an important component of future ubiquitous communications systems. Satellite networks will be especially useful to interconnect remote sensor networks. Therefore, satellite networks should provide the needed QoS, differentiation of services and at the same time keep the required scalability. The purpose of this paper is to propose a new Diffserv‐based scheme of bandwidth allocation during congestion, called proportional allocation of bandwidth (PAB).

The paper suggests a method for implementing PAB without storing per‐flow state, which makes the scheme scalable and simple and shows, by simulation, the advantages of using PAB in IP satellite networks.

The paper finds that PAB can be used in geostationary earth orbit, MEO and low earth orbit satellite networks. In PAB, during congestion all flows get a share of IP available bandwidth, which is in proportion to their subscribed information rate.

The simulations described in this paper show that the performance of PAB scheme is good on congested satellite networks.

This work is motivated by the need to develop decentralized peer‐to‐peer (P2P) approaches to support e‐learning and teaching activity in virtual universities. This paper aims to present the implementation of the JXTA‐based e‐learning P2P system.

The design and implementation of a smart box environment that will be used for stimulating the learners to increase the learning efficiency is shown. The smart box is integrated with the JXTA‐overlay by using efficient message sending between peers in the system.

The proposed e‐learning P2P system is a useful tool for monitoring and controlling learners' activity.

In the future, other effective stimulation for each learner using IC tag card will be added. Also, the Servo Motor has 12 control ports, so these will be used for implementing other stimulating functions. It is planned to extend the system with functionalities for presence mechanism of students in classrooms and activities.

The proposed system is evaluated by experimental results and it has a good performance.

This paper proposes and implements a novel e‐learning system, which is based on P2P, web and sensor technologies.

A cyber world (CW) is a digitized world created on cyberspaces inside computers interconnected by networks including the Internet. Following ubiquitous computers, sensors, e‐tags, networks, information, services, etc., is a road towards a smart world (SW) created on both cyberspaces and real spaces. It is mainly characterized by ubiquitous intelligence or computational intelligence pervasion in the physical world filled with smart things. In recent years, many novel and imaginative researches have been conducted to try and experiment a variety of smart things including characteristic smart objects and specific smart spaces or environments as well as smart systems. The next research phase to emerge, we believe, is to coordinate these diverse smart objects and integrate these isolated smart spaces together into a higher level of spaces known as smart hyperspace or hyper‐environments, and eventually create the smart world. In this paper, we discuss the potential trends and related challenges toward the smart world and ubiquitous intelligence from smart things to smart spaces and then to smart hyperspaces. Likewise, we show our efforts in developing a smart hyperspace of ubiquitous care for kids, called UbicKids.

The growing use of internet-based learning (IBL) platforms in institutions of higher education is producing profound changes in the traditional teaching learning process worldwide. This paper aims to identify and understand the ways in which higher education institutions draw benefits by the use of such means, synthesizing the literature research.

The study synthesized the literature research by using a mixed method approach in which both Web of Science (WoS) and bibliographic techniques were used to retrieve the relevant data base.

The comprehensive review of the literature suggests that communication technology (CT), massive open online courseware (MOOCs), social networking sites (SNSs), blogs, real simple syndication (RSS) and YouTube are creating new possibilities and avenues of collaborative learning by transforming the traditional class and teacher-centric system.

Multiplicity of the IBL platforms and rapid technological obsolesce are some of the limitations of this paper.

The findings of this study are highly useful in developing a strategic framework to accelerate the integration of IBL platforms to make teaching learning process more interactive and informative.
