Mobility prediction based routing for minimizing control overhead in mobile ad hoc networks

Routing in ad hoc networks faces significant challenges due to node mobility and dynamic network topology. In this work we propose the use of mobility prediction to reduce the search space required for route discovery. A method of mobility prediction making use of a sectorized cluster structure is described with the proposal of the Prediction based Location Aided routing (P-LAR) protocol. Simulation study and analytical results of the of P-LAR find it to offer considerable saving in the amount of routing traffic generated during the route discovery phase.

Mobile phone etiquette: a cross-national comparison

As a social medium, mobile telephony permits ubiquitous communication. This has led to concerns about the intrusiveness of the medium, which in turn has seen the development of a social etiquette governing mobile phone use. This study of Australian and US tertiary students showed that there was widespread but not universal agreement that usage was inappropriate in places of worship, classrooms and libraries or while driving a car. Australians were more tolerant of mobile usage than Americans in most situations, apart from driving. SMS was more broadly tolerated, including in class and in cinemas.

Transaction management in a replicated and mobile environment

Reports the design of three-level transaction processing model which provides efficient transaction management in a replicated and mobile environment. The model uses a promary/non-primary replication control protocol to enable transaction processing with fast user response time at any distributed site including mobile hosts. A Web-based design with an implementation of a prototype application system shows a concrete example of how to adopt the transaction model over distributed databases.

Web usability guidelines for smartphones : a synergic approach

The mobile phones that we carry with us all the time have started becoming increasingly sophisticated and consequently are referred to as “Smartphones”. Smartphones today are extremely powerful and, in addition to making phone calls, are capable of performing a variety of other functions. One very important function is the ability to access the Internet for a wide number of purposes. An obstacle that these users face is that access to the Internet is through a tiny interface, which is in sharp contrast to the typically large, flat-screen monitor. Unfortunately, many websites are neither designed for nor suitable to be accessed from these small devices. With relatively little effort, however, the developers of the websites can make the web interfaces more appropriate for Smartphones and hence accessible to a much larger audience. In this paper, we focus on “web usability”, a term essentially concerned with the ease of accessing and entering information on websites. We compile and synergize several different guidelines with the intent of increasing the web usability of Smartphones.

Mobile technology platforms for flexible access to information resources : considerations in the use of ebook readers, smart phones, netbooks and iPads

Smart phones are everywhere, people are taking eBook readers on holiday, the iPad has queues of people wanting to buy one, and some netbooks can fit in a pocket. The technology is attractive and increasingly affordable – how can it help an individual in their access to and use of texts, journals, databases, clinical sources, the web and day-to-day information? The Library has been investigating and trialling mobile devices during 2010, and has received interesting feedback from staff and students on the effectiveness of the technology in the University and personal environments. Each device has its strengths and weaknesses depending on the needs of the individual or activity it is supporting – productivity, research, study, clinical or recreational. The presentation will explore these issues along with some of the practical implications at Deakin, and international experiences in academic environments.

Retake Melbourne : mobile application for re-photography and comparative imaging research

A project of interpretive and comparative re-photography, making use of the collection of Mark Strizic's images and the documents related to his career, held by the State Library, as a basis. Strizic died in 2012. It is now 50 years since his work began to illustrate the period of the 1960s when architecture of the Gold Rush era coexisted side-by-side with, and was being replaced by, curtain-glass high-rise office buildings. It is the position of the researchers that not sufficient attention has been given to Mark Strizic’s reaction to what he saw as a plague of ugliness pervading Australian city-scapes, developing a distinctive aesthetic that in turn made his work useful to commentators like Robin Boyd and David Saunders. Strizic operated from a unique perspective as a migrant with an architectural heritage from his father Zdenko, prominent architecture professor in Croatia, and visiting professor of architecture at Melbourne University in the 1960s. Precise re-photography alongside creative work will enable a comparison of Melbourne now with fifty years ago. The public will be able to participate in and contribute to the project via a crowd-funded custom-made app. Half a century has passed since Strizic made his photographs of Melbourne. In so many cases buildings have disappeared or altered, streetscapes have changed and the appearance of Melburnians have changed as have their habits of using the city. A selection of Strizic’s photographs of Melbourne locations can be rephotographed by the public using the methods devised by Mark Klett, assisted by the app software. This will provide a core of documentary imagery of benefit in framing and completing the rest of this project and to future research through comparisons over the time span. The app enables the location on a map of the site and orientation of photographs taken by Strizic. Photographs are downloaded onto users’ devices from the online SLV Strizic picture catalogue. They appear in the app as transparent templates so that users can line up their own re-photograph with accuracy. They will be able to upload their resultant images to a server and they will be available to the Library as an archive enabling direct comparison with the Strizic holdings. It is anticipated that involvement and participation of the public will elevate the profile of the project and publicise the SLV collections and encourage their increased usage and popularity.

A review of the current status of mobile apps in education - implication for emerging countries business education strategies

Mobile applications (in short: mobile apps) are software applications designed to run on mobile devices such as smart phones and tablet computers. These technologies have come a long way since the opening of the Apple App Store in 2008, especially in their applications for business, information, communication, health and gaming. Most mobile devices are capable of processing and disseminating information in an efficient way. Smart devices, such as the iPhone or iPad, are equipped with innovative functionalities and unique features for easy delivery of content, information sharing, and collaborative work over the Internet. This is the basis for the use of these technologies in the education industry.

Is this an ipad revolution or mobile learning revolution? A global perspective across countries : " iWorld, iLearn"

 This evolution of mobile technologies and application integration in education across the world has provided a shift to a new learning environment via various mobile platforms.Educational institutions globally are missing to identify specific mobile technologies initiatives and strategies as a method to evaluate these mobile technologies and to expose both students and teachers to the potential it engenders.This panel will undertake a cross country comparison among culturally diverse countries: Turkey,UAE,USA,Lebanon,Iceland,Israel,Japan,Germany.Questions will be raised such as:Why some countries are branding mobile learning and their integration of these technologies has been made device specific, app specific and operating system specific?Is this the right approach?The digital gap between countries will be discussed?Availability access, barriers and limitations for some countries are described.We will try to figure out similarities,differences and challenges among these countries.

iTeach we learn via mobile apps : "a case study in a business course"

Mobile smart phones and Mobile applications (apps) can be seen as an added opportunity for education and for teachers in particular, this can be true if educational institutions are willing to enable this type of delivery mechanism. With the recent development of app technologies in today’s society and the shift towards mobile technologies (devices and applications), it seems hard to imagine better devices and tools that can grant students easy and on demand access to learning content. These smart devices and technologies are multitasking and can offer variety of educational apps that teachers and students are able to integrate into their daily learning activities and can carry with them anywhere. In this paper mobile apps and their integration in education are discussed, a case study on the use of three mobile apps (e-Lecture-Producer, Dropbox and QR Code) in an educational setting in a Business e-commerce course is described. Results and outcomes are discussed based on the results from the case study.

Mobile devices in social contexts

The development of mobile devices has occurred with unprecedented pace since the late nineties, and the increase of generic services has proliferated in most developed countries, driven by the expanding technological capabilities and performance of mobile platforms. This dissertation investigates how consumer objectives, orientation and behavior can aid in explaining the adoption and use of a new type of mobile devices: "app phones". This dissertation focuses its effort on two focal influences of adoption and use; social influences and competing forces. Through a qualitative case study and field study this dissertation explores early adoption and use of iPhones. The case study is a one-shot cross-sectional case study that investigates five individuals, related through the same social network, and their decision to adopt an iPhone prior to its release in Denmark. This adoption decision engenders high switching costs as adopters lack references to imitate and need skills to unlock and jailbreak their iPhones to make them work on Danish networks. The specific purpose of the case study is to explore how social influences impact mobile users' early adoption decisions, as it is well known in the literature that people with similar characteristics, tastes, and beliefs often associate in the same social networks and, hence, influence each other. The field study is cross-sectional with multiple snapshots and explores fifteen individuals part of the same university study, who recieves an iPhone for a period of seven months short after its release in Denmark. The specific purpose of the field study is to explore how competing forces of iPhone usage influence assimilation, i.e. the degree to which the iPhone is used, over time. The dissertation is reported through four articles and is directed at both academic researchers and practitioners. The study emphasizes the importance of social influences and competing forces in the investigation of adoption and use of certain mobile devices.

Is there an app for that? Looking at possibilities and challenges of digital tools for literacy education

 Portable electronic devices such as the iPad are increasingly taking a place in contemporary childhood experiences including those of schooling (O'Mara & Laidlaw, 2011). As digital media theorists suggest, such new tools invite both "hope and fear" (Gee and Hayes, 2011, p.4), consistent with literacy innovations across history. In both Canada and Australia, educational stakeholders are looking to touch screen devices as having much promise, particularly within literacy education. This paper presentation examines the possibilities as well as the challenges and imagines the future of such digital tools within literacy education, looking at experiences and perspectives in Canada and Australia.
We take a qualitative ecological mode of inquiry approach to our data collection and analysis, drawing on complexity thinking (Davis & Sumara, 2006) to bring our multiple points of view together as diversely positioned educators. Within our individual sites, each author has collected data as a part of longer-term research projects. In this paper presentation we compare and contrast these data sets, attending to significant intersections and juxtaposing issues of culture and globalization. Within this mode of inquiry we value the particularity of the individual contexts, and locate them alongside one another in a larger bricolage (Johnson, 2010).
We examined observational data, documents and artifacts using Freebody and Luke's (1990) four resources model and the further adaptions of this model (see e.g. Luke & Freebody, 1999) to understand how touch screen devices are being used and positioned as literacy tools. We have engaged in collaborative data analysis, often working 'together' using digital tools ourselves to enable collective conversations. For example, we have used Facetime on iPads and laptops, Skype and email to facilitate collective analyses. We applied iterative and recursive analyses to uncover reoccurring themes both within and across sites and artifacts.
As our paper will elaborate, mobile touch screen devices such as iPads are widely being taken up in educational settings, and regarded as having the possibility to shift teaching and learning in new directions, as "paradigm breakers" (p. 4, Gov't of AB, 2011). As personal, mobile devices, these tools present challenges that require educators to think differently about learning and teaching. Our paper also addresses the opportunities and affordances that iPads might offer to learners, as having the potential for students to engage in playful exploration, and in the role of designers, creators, and producers, rather than as passive recipients.

Mobile phone-based electrochemiluminescence sensing exploiting the 'USB On-The-Go' protocol

A low-cost system to generate, control and detect electrochemiluminescence using a mobile smartphone is described. A simple tone-detection integrated circuit is used to switch power sourced from the phone's Universal Serial Bus (USB) 'On-The-Go' (OTG) port, using audible tone pulses played over the device's audio jack. We have successfully applied this approach to smartphones from different manufacturers and with different operating system versions. ECL calibrations of a common luminophore, tris(2,2′-bipyridine)ruthenium(II) ([Ru(bpy)3]²⁺), with 2-(dibutylamino)ethanol (DBAE) as a co-reactant, showed no significant difference in light intensities when an electrochemical cell was controlled by a mobile phone in this manner, compared to the same calibration generated using a conventional potentiostat. Combining this novel approach to control the applied potential with the measurement of the emitted light through the smart phone camera (using an in-house built Android app), we explored the ECL properties of a water-soluble iridium(III) complex that emits in the blue region of the spectrum. The iridium(III) complex exhibited superior co-reactant ECL intensities and limits of detection to that of the conventional [Ru(bpy)3]²⁺ luminophore.
