J2ME-Based Mobile Virtual Laboratory for Engineering Education
Akram Alkouz, A. Y. Al-Zoubi, Mohammed Otair
Abstract
A mobile virtual laboratory is developed to help students perform virtual experiments using mobile devices to make it possible for teaching to be conducted anytime anywhere.In addition, resources and equipment can be integrated and shared efficiently where an environment is created to promote learning interests and efficiency by using mobile devices via the Internet and the GPRS telecommunication networks. Java wireless communication technologies were used in the design which implements a multi-tier architecture in order to integrate different fields of technology. The ultimate objective is to improve the scalability of the system and to allow for the use of Scalable Vector Graphics which makes it possible for developers to create interactive graphical content, with the ability to zoom and resize on displays with different resolutions and aspect ratios.

Distributed Mobile Agents for reliable cluster management in MANETs
Hatem Mahmod Hamad
Abstract
A mobile wireless ad hoc network is formed dynamically without a need for a pre-existing infrastructure. This kind of dynamic networks has been used in commercial, cultural, and environmental applications including emergency situations. Managing such networks is a challenging task. In this paper, I propose a management solution that achieves reliable cluster management in clustered ad hoc networks. The solution is based on mobile agent technology. The cluster head performs many jobs to manage the cluster. My proposed idea is to distribute the CH jobs among some nodes called job-carriers. I implement each job in a mobile agent which resides on one of the job-carriers. Election of the job-carriers is based on a periodically calculated number called Connectivity Number (CN). Each node calculates its CN by counting its neighbors that fall in the 1-hop range of the cluster. The highest-CN nodes have the chance to be jobcarriers. Simulation results show accomplishing semi-static structure and enhancing the performance of the ad hoc network.

Evaluating the Cognitive Aspects of User Interaction with 2D Visual Tagging Systems
Samuel Olugbenga King
Abstract
There has been significant interest in the development and deployment of visual tagging applications in recent times. But user perceptions about the purpose and function of visual tagging systems have not received much attention. This paper presents a user experience study that investigates the cognitive models that novice users have about interacting with visual tagging applications. The results of the study show that although most users are unfamiliar with visual tagging technologies, they could accurately predict the purpose and mode of retrieval of data stored in visual tags. The study concludes with suggestions on how to improve the recognition, ease of recall and design of visual tags.

Exploring the transformations of interaction in mobile work contexts
Teija Vainio, Virpi Oksman, Heli Wigelius, Maiju Markova, Minna Kulju
Abstract
The usage of work related mobile services is often very complex, affected by a multitude of intertwined factors including the technological, environmental and human. Un-derstanding how to model the complexity of mobile work and particularly its mobile interaction would be beneficial in ensuring the success of mobile services in user’s long-term, goal-oriented usage. Previous attempts to evaluate success factors in mobile business services have concen-trated on rigid analytical tools modeling users and tasks and mainly focusing on understanding routine work tasks and standard information exchange between different users. However, this covers only a narrow field of mobile work and it is argued here that existing analytical tools do not suffi-ciently consider factors arising from different levels of mobility and the temporariness and non-routine tasks of mo-bile work. In this paper we present a process oriented approach, 'MoBiS Map, derived from Actor-Network theory, to describe the complex network of interactions and the transformation of interactions. We argue that our approach is a useful analytical tool when the focus is on examining the transformation of interactions that takes place when mobile work services are implemented. This is a methodological paper aiming to better understand the transformation of mobile interactions, and therefore to support development of mobile business services.

Abstract
The mobile devices related industries are subject to rapid change, driven by technological advances and dynamic consumer behaviour. Hence, the understanding of the mobile devices markets is an important step in the analysis phase of mobile applications development. In this paper, a brief description of the different markets is introduced followed by an analysis of the main features of the markets leaders’ devices which are important in the development process of mobile web applications. Finally, approaches are proposed to deal with the mobile devices diversity.
