Mobile computing devices, such as tablets, smartphones, PDAs, and game remote controllers, become very popular in our daily life. This article discusses how to turn these devices, more specifically smartphones and Nintendo Wii remotes (in short as Wiimote), into computer remote controllers. In the smartphone-based system, a smartphone is extended to be the computer’s wireless keyboard and mouse. The smartphone and the computer talk to each other through either wireless Ad Hoc or Wi-Fi access point network. In the Wiimote-based system, a Wiimote is turned into computer’s mouse, where the user moves the mouse cursor by waving the Wiimote in air, and generates mouse events through Wiimote buttons. The Wiimote communicates with the computer through Bluetooth. These systems can be used in conference rooms, classrooms, project seminar rooms, and even people’s living rooms, where a projector screen or a big-screen TV serves as the computer monitor.

Due to the rapidly increasing of the mobile devices connected to the internet, a lot of researches are being conducted to maximize the benefit of such integration. The main objective of this paper is to enhance the performance of the scheduling mechanism of the mobile computing environment by distributing some of the responsibilities of the access point among the available attached mobile devices. To this aim we investigate a scheduling mechanism framework that comprises an algorithm provides the mobile device with the authority to evaluate itself as a resource. The proposed mechanism is based on the proposing of “self ranking algorithm (SRA)” which provides a lifetime opportunity to reach a proper solution. This mechanism depends on event-based programming approach to start its execution in a pervasive computing environment. Using such mechanism will simplify the scheduling process by grouping the mobile devices according to their self -ranking value and assign tasks to these groups. Moreover, it will maximize the benefit of the mobile devices incorporated with the already existing grid systems by using their computational power as a subordinate value to the overall power of the system. Furthermore, we evaluate the performance of the investigated algorithm extensively, to show how it overcomes the connection stability problem of the mobile devices. Experimental results emphasized that, the proposed SRA has a great impact in reducing the total error and link utilization compared with the traditional mechanism.

Wireless networks and the subsequent mobile communication are growing by leaps and bounds in the past years and the demand for connection without cables is certainly high. Nowadays, wireless networks are quite common and can be found on university campuses, corporate offices and in public places like hotels, airports, coffee shops and so forth. Not only are mobile devices getting smaller and cheaper, they are also becoming more efficient and powerful, capable of running applications and network services. This is causing the uncontrollable growth of mobile computing as we are witnessing today. Among the many number of applications and services that are executed by mobile devices, network and data services are in high demand. Brief descriptions of some selective wireless technologies that help mobile computing, like IEEE 802.11 networks (with infrastructure mode and ad-hoc mode), Bluetooth, HomeRF, WiMAX and cellular technologies are given below.

Security Issues

Now a day’s mobile communication has become a serious business tool for the users. Mobile devices are mainly used for the applications like banking, e-commerce, internet access, entertainment, etc. for communication. This has become common for the user to exchange and transfer the data. However people are still facing problems to use mobile devices because of its security issue. This paper deals with various security issues in mobile computing. It also covers all the basic points which are useful in mobile security issues such as categorisation of security issues, methods or tactics for success in security issues in mobile computing, security frameworks.

The well-known password authentication mechanisms are widely used in networks to protect resources from unauthorized access. The ad hoc networks, due to their dynamic and lack of network infrastructure features, require authentication schemes to ensure security. In this paper, we propose a new threshold password authentication scheme for ad hoc networks. Our scheme can be efficiently implemented in mobile devices, and can achieve mutual authentication with registered users.

Abstract When physical communication network infrastructures fail, infrastructure-less communication networks such as mobile ad-hoc networks (MANET), can provide an alternative. This, however, requires MANETs to be adaptable to dynamic contexts characterized by the changing density and mobility of devices and availability of energy sources. To address this challenge, this paper proposes a decentralized context-adaptive topology control protocol. The protocol consists of three algorithms and uses preferential attachment based on the energy availability of devices to form a loop-free scale-free adaptive topology for an ad-hoc communication network. The proposed protocol has a number of advantages. First, it is adaptive to the environment, hence applicable in scenarios where the number of participating mobile devices and their availability of energy resources is always changing. Second, it is energy-efficient through changes in the topology. This means it can be flexibly be combined with different routing protocols. Third, the protocol requires no changes on the hardware level. This means it can be implemented on all current phones, without any recalls or investments in hardware changes. The evaluation of the protocol in a simulated environment confirms the feasibility of creating and maintaining a self-adaptive ad-hoc communication network, consisting of multitudes of mobile devices for reliable communication in a dynamic context.

<p>The paper discusses the results of a study which explored advanced learners of English engagement with their mobile devices to develop learning experiences that meet their needs and goals as foreign language learners. The data were collected from 20 students by means of a semi-structured interview. The gathered data were subjected to qualitative and quantitative analysis. The results of the study demonstrated that, on the one hand, some subjects manifested heightened awareness relating to the advantageous role of mobile devices in their learning endeavors, their ability to reach for suitable tools and retrieve necessary information so as to achieve their goals, meet their needs and adjust their learning of English to their personal learning styles, and on the other, a rather intuitive and/or ad hoc use of their mobile devices in the classroom.</p>

The evolution of mobile devices and the development of high speed wireless networks have supported a widespread use of these devices with increasingly more complex applications. This reality has fostered the research in the field of information visualization in mobile devices. However, the limited screen space, resource constraints and interaction restrictions impose difficulties to developers and users of these applications. An approach to address these problems is to adapt the visualization to the user context. However, these proposals are normally designed in an ad-hoc fashion and are difficult to generalize. In addition, existing solutions are focused only in some subset of possible characteristics of the user context or only address a very specific domain and related adaptations. The objective of this paper is to present the design of a framework for adaptive mobile visualization (AMV) applications, denominated Chameleon, and the development and evaluation of prototypes that use this conceptual-based framework.
