Abstract

This is the first issue of Volume 10 of the International Journal of Pervasive Computing and Communication, which commences the tenth year of this journal which has served a large community of researchers and academics around the world with the highest quality articles reporting on the state-of-the-art research results and scientific findings in the field of pervasive computing and communication. This issue consists of a collection of selected high-quality papers from MoMM2013 conference. The International Conference on Advances in Mobile Computing and Multimedia (MoMM) is one of the flagship conferences organised by the International Organization for Information Integration and Web-based Applications & Services (iiWAS) which aims at fostering collaborations and exchanges of ideas and information among students, professionals and researchers interested in the field of information integration and web applications and services. MoMM conferences have particular focuses on underlying models, protocols, algorithms, mechanisms and technology infrastructure which enable mobile platforms and interaction for various multimedia services. The selected papers represent and reflect the latest state of the art of research and development in these related areas which help identify opportunities and challenges for interested researchers and technology and system developers and inspire and provoke follow-up research in the time to come. The paper "Integrating the audience into a theatre performance using mobile devices" describes the Theatre Engine project which explores the integration of mobile devices such as smart phones and tablet computers as user interaction mechanisms for live theatrical performances. The platform used in the project consists of a network of mobile Android-based devices that communicate with a server managing a live theatrical performance and additional systems that provide projected graphics within the performance space, dynamic instructions to live musicians and control of theatrical equipment including robotic lighting. The system is under the live control of a stage managers and show runner. This paper describes the technical details of the approach and system platform including the classification of the roles of users and their activities. It also explores the concept of blurring the distinction between real and virtual performance. The paper "A scalable clustering scheme and its performance evaluation" addresses one of the key fundamental problems in Mobile Ad hoc Networks (MANETs), namely scalability. The paper introduces a new, efficient and scalable, clustering scheme for MANETs, and further conducts performance evaluation by simulating a MANETs of a large number of mobile nodes. Comparison between the performance of the proposed scheme with a number of existing clustering schemes such as lowest ID, highest degree and WCA, based on a number of performance metrics has shown that the proposed scheme outperforms other clustering schemes. The paper "Exploring network selection techniques for multicast groups in heterogeneous wireless environments" aims to address the challenging problem of coexistence of various wireless access networks and the ability of mobile terminals to make an optimal selection of serving networks for multicast groups by switching dynamically among different networks. The study analyzes the operation of the wireless heterogeneous network, including the decision-making process and the data that needs to be sent between different network components. Based on this analysis it built a mathematical model of the network and defined a minimization algorithm of multicast streams in the system. It has been proved that the proposed heuristic solutions substantially reduce usage of bandwidth in mobile networks and exchange of information between the network components. The paper "Modelling users, context and devices for adaptive user interface systems" provides a comprehensive review on the state-of-the-art of adaptive user interface systems. It studies and compares adaptive user interface systems over the past 20 years. Based on this analysis the authors detail the most significant models from which a specific novel model incorporating three main entities, i.e. users, context and devices have been proposed and elaborated. The paper "SmartCopter – enabling autonomous flight in indoor environments with a smartphone as on-board processing unit" introduces a low-cost unmanned aerial vehicle (UAV) for autonomous flight and navigation in GPS-denied environments using an off-the-shelf smartphone as its core on-board processing unit. The research adopts an algorithmic approach for mapping and localization that does not require GPS coverage of the target area, therefore autonomous indoor navigation is made possible. The approach is independent from additional ground hardware and the UAV core unit can be easily replaced with more powerful hardware that simplifies set-up updates as well as maintenance. The study opens up future research on 3D self-localization and dense mapping using mobile hardware as the only on-board processing unit. The paper "An investigation into the usability of touch-based interaction" aims to investigate the usability of touch-based user interfaces with the ultimate purpose of providing guidance for user interface designers and developers. The study adopts an empirical approach using an experiment to test the effectiveness and user satisfaction of touch-based interaction compared with equivalent mouse-based interaction. Two abstract type tasks and one contextualised task using the two methods of interaction have been designed for the study. The experimental data have been measured and analysed based on errors, task time and user satisfaction, which has shown that overall the mouse-based interaction was faster, caused fewer errors and was preferred by the participants.
