EDITORIAL PREFACE

IJMCMC 1(1)

Ismail Khalil, Johannes Kepler University Linz, Austria Edgar Weippl, Secure Business Austria - Security Research, Austria

The field of mobile computing and multimedia is expanding in an unprecedented pace. Indicators are the rapidly increasing penetration of the cellular phone market around the world, and the mobile computing market is growing nearly twice as fast as the desktop market. In addition, technological advancements have significantly enhanced the usability of mobile communication and computer devices. For these reasons and more, the editors believe that this is the right time to introduce a specialized journal in the area of mobile computing and multimedia communications. The editors hope readers will gain greater insight into mobile multimedia as they relate to applications, management, and opportunities within any given constructs.

PAPER ONE

Scenario-Based Cluster Formation and Management in Mobile Ad Hoc Networks

V. S. Anitha, National Institute of Technology - Calicut, India M. P. Sebastian, National Institute of Technology - Calicut, India

This article proposes a scenario-based algorithm for cluster formation and management in mobile ad hoc networks. Depending on the application a centralized or distributed algorithm based on (k, r) –dominating set is used for the selection of clusterheads and gateway nodes. Here k is the minimum number of clusterheads per node in the network and r is the maximum number of hops between the node and the clusterhead. The quality of the clusterhead is a function of various metrics, which include connectivity, stability, and residual battery power.

PAPER TWO

Fast Vector Quantization Encoding Algorithms for Image Compression

Ahmed Swilem, Minia University, Egypt

Vector quantization (VQ) is a well-known compression method. In the encoding phase, searching the closest codeword in the codebook is a time-consuming task. In this article, two fast encoding algorithms for VQ are proposed. To reduce the search area and accelerate the search process, the first algorithm utilizes three significant features of a vector that are the norm and two projection angles to two projection axes. The second algorithm uses the first two features as in the first algorithm with the projection value of the vector to the second projection axe. The algorithms allow significant acceleration in the encoding process. The author presents experimental on image block data.

PAPER THREE

FCVW: Experiments in Groupware

Ivan Tomek, Acadia University, Canada Elhadi Shakshuki, Acadia University, Canada

Pervasiveness of the Internet and increasing geographical dispersal of work teams result in continuously growing importance of groupware - software that supports collaboration within groups. Numerous applications have been developed to address collaboration needs and many are widely used but don’t fully satisfy work team requirements and the Internet potential. This paper surveys several groupware products and describes FCVW (Federated Collaborative Virtual Workspace), an experimental project designed to explore certain groupware aspects that are not sufficiently addressed by existing products.

PAPER FOUR

A Cross-Layer Model for Video Multicast Based TCP-Adaptive FEC over Heterogeneous Networks

Ghaida A. AL-Suhail, University of Basrah, Iraq Liansheng Tan, Central China Normal University, China Rodney A. Kennedy, The Australian National University, Australia

In this article, the authors present a simple cross-layer model that leads to the optimal throughput of multiple users for multicasting MPEG-4 video over a heterogeneous network. For heterogeneous wired-to- wireless network, at the last wireless hop there are bit errors associated with the link-layer packets that are arising in the wireless channel, in addition of overflow packet dropping over wired links. The authors employ a heuristic TCP function to optimize the cross-layer model of data link and physical (radio-link) layer. An adaptive forward-error-correction (FEC) scheme is applied at the byte- level, as well as at the packet-level. The corresponding optimal video quality can be evaluated at each client end.

PAPER FIVE

A Model for Mobile Learning Service Quality in University Environment

Nabeel Farouq Al-Mushasha, Jerash Private University, Jordan Shahizan Hassan, Universiti Utara Malaysia, Malaysia

It is generally known that accessibility and mobility are the main barriers for effective implementation of electronic learning; however, the advent of mobile technology could be a potential solution to remove the barriers. Nevertheless, there is a lack of research that addresses the issue of mobile learning service quality in a university environment. This study aims to propose a service quality model for m- learning in a university environment. A questionnaire survey was conducted which measured ten dependent variables and three independent variables. The dependent variables were meant to measure service quality, information quality, and system quality. The dependent variables were meant to measure the causal relationship between overall learners’ perceived service quality, learner satisfaction, and learner behavioral intention to use the service in future.

PAPER SIX

Evaluating E-Communities of Wireless Networks Worldwide

Theodoros I. Kavaliotis, University of Macedonia, Greece Anastasios A. Economides, University of Macedonia, Greece

Many people communicate among themselves using wireless networks. They have developed e-communities in order to discuss issues about their network development, problems, opportunities, and wireless technology advances among others. The purpose of this article is to present an evaluation framework and analyze the current status of such electronic communities of wireless networks (ECWNs) in four continents: Africa, America, Europe and Oceania. The evaluation framework contains fifty criteria categorized into four categories, and then fifty-seen ECWNs were evaluated using the criteria.
