    Mobile devices and mobile applications have a significant effect on the present and on the future of the software industry. The diversity of mobile platforms necessitates the development of the same mobile application for all major mobile platforms, which requires considerable development effort. Mobile application developers are multiplatform developers, but they prioritize the platforms, therefore, not all platforms are equally important for them. Appropriate methods, processes and tools are required to support the development in order to achieve better productivity. The main motivation of our research activity is to provide a method, which increases the development productivity and the quality of the applications and also reduces the time to market. The paper discusses our model-driven results on the field of multi-mobile platform development

    Mobiilitehnoloogiate areng ja nutitelefonide kiire levik loob uusi vĂ”imalusi mobiilirakenduste arendamiseks ning palju rĂ”hku pannakse mĂ€ngudele. Loodavad mĂ€ngud muutuvad aga keerulisemaks, sest ĂŒha enam kasutatakse keskkonnast tulevat informatsiooni, et kohandada mĂ€ngu vastavalt kasutaja asukohale ja kontekstile. MĂ€nge, mis seovad kasutaja fĂŒĂŒsile asukoha ja oleku virtuaalmaailmaga keskkonnateadlikuks mĂ€nguks. Üha enam luuakse rakendusi veebiplatvormile, mitte kindlatele operatsioonisĂŒsteemidele, sest veebitehnoloogiad vĂ”imaldavad luua vĂ”rdvÀÀrse funktsionaalsuse ning kasutajamugavusega rakendusi. VeebipĂ”histe rakenduste suurimaks eeliseks on see, et nende tööks on vaja ainult veebibrauserit ning igale operastioonisĂŒteemile ei pea kirjutama eraldi programmi. Antud tehnoloogiad on jĂ”udnud ka mobiilimaailma, kus iga operatsioonisĂ”steemi jaoks peab arendama eraldiseisva rakenduse, sest iga tootja sĂŒsteem on teistest erinev. Antud bakalaurusetöö eesmĂ€rgiks on luua veebitehnoloogiaid kasutades mobiilimĂ€ng, mille juhtimiseks kasutatakse nutitelefonis olevaid sensoreid ning lisaks Arduino mikrokontrolleritest tulevat vĂ€liskeskoona informatsiooni. Antud bakalaurusetöö suurimaks panuseks on PhoneGap raamistikule loodud moodul, mis vĂ”imaldab pĂ€rida Arduino mikrokontrollerist saadetud sensorite informatsiooni kliendipoolsest koodist, mis tavaliste lahendustega pole vĂ”imalik.Latest technological achievements in mobile and open-source electronics platforms made it possible to develop pervasive applications that use environmental information to enhance software usability aspects in real-time, like in the case of context-aware mobile games. However, the development of this kind of pervasive applications is tied to speci c aspects owned by each mobile platform (e.g. programming language, SDK and tools, etc.). Moreover, a considerable effort and knowledge in low-level programming techniques is required for porting the applications between platforms, and thus in general most of the solutions are targeted at particular platform. In order to investigate the possibility of creating portable pervasive applications that combine sensor information from the multiple micromechanical artefacts embedded within the smartphones, we used contextual sensor data provided by Arduino Microcontroller. The current thesis proposed extending the existing implementation of PhoneGap to create hybrid mobile applications based on HTML5 that are easy to port, maintain and reuse

    Body Sensor Networks (BSN) appeared as an application of Wireless Sensor Network (WSN) to medicine and biofeedback. Such networks feature smart sensors (biosensors) that capture bio-physiological parameters from people and can offer an easy way for data collection. A new BSN platform called Sensing Health with Intelligence Modularity, Mobility and Experimental Reusability (SHIMMER) presents an excellent opportunity to put the concept into practice, with suitable size and weight, while also supporting wireless communication via Bluetooth and IEEE 802.15.4 standards. BSNs also need suitable interfaces for data processing, presentation, and storage for latter retrieval, as a result one can use Bluetooth technology to communicate with several more powerful and Graphical User Interface (GUI)-enabled devices such as mobile phones or regular computers. Taking into account that people currently use mobile and smart phones, it offers a good opportunity to propose a suitable mobile system for BSN SHIMMER-based networks. This dissertation proposes a mobile system solution with different versions created to the four major smart phone platforms: Symbian, Windows Mobile, iPhone, and Android. Taking into account that, currently, iPhone does not support Java, and Java cannot match a native solution in terms of performance in other platforms such as Android or Symbian, a native approach with similar functionality must be followed. Then, four mobile applications were created, evaluated and validated, and they are ready for use

    This thesis describes research on the use of Java to develop cross-platform computer vision applications for mobile phones with integrated cameras. The particular area of research that we are interested in is Mobile Augmented Reality (AR). Currently there is no computer vision library which can be used for mobile Augmented Reality using the J2ME platform. This thesis introduces the structure of our J2ME computer vision library and describes the implementation of algorithms in our library. We also present several sample applications on J2ME enabled mobile phones and report on experiments conducted to evaluate the compatibility, portability and efficiency of the implemented algorithms

    An investigation into interoperable end-to-end mobile web service security

    The capacity to engage in web services transactions on smartphones is growing as these devices become increasingly powerful and sophisticated. This capacity for mobile web services is being realised through mobile applications that consume web services hosted on larger computing devices. This thesis investigates the effect that end-to-end web services security has on the interoperability between mobile web services requesters and traditional web services providers. SOAP web services are the preferred web services approach for this investigation. Although WS-Security is recognised as demanding on mobile hardware and network resources, the selection of appropriate WS-Security mechanisms lessens this burden. An attempt to implement such mechanisms on smartphones is carried out via an experiment. Smartphones are selected as the mobile device type used in the experiment. The experiment is conducted on the Java Micro Edition (Java ME) and the .NET Compact Framework (.NET CF) smartphone platforms. The experiment shows that the implementation of interoperable, end-to-end, mobile web services security on both platforms is reliant on third-party libraries. This reliance on third-party libraries results in poor developer support and exposes developers to the complexity of cryptography. The experiment also shows that there are no standard message size optimisation libraries available for both platforms. The implementation carried out on the .NET CF is also shown to rely on the underlying operating system. It is concluded that standard WS-Security APIs must be provided on smartphone platforms to avoid the problems of poor developer support and the additional complexity of cryptography. It is recommended that these APIs include a message optimisation technique. It is further recommended that WS-Security APIs be completely operating system independent when they are implemented in managed code. This thesis contributes by: providing a snapshot of mobile web services security; identifying the smartphone platform state of readiness for end-to-end secure web services; and providing a set of recommendations that may improve this state of readiness. These contributions are of increasing importance as mobile web services evolve from a simple point-to-point environment to the more complex enterprise environment

    Der Markt fuer mobile Applikationen ist in den letzten Jahre drastisch gewachsen, vorallem durch die staendige steigende Zahl and Mobiltelefonen. Gruende fuer den raschen Anstieg sind unter anderem die steigende Anzahl an Applikationsportalen von Endgeraeteherstellern sowie Telekomunternehmen. Durch die Vielzahl an unterschiedlichen Endgeraeten mit konkurrierenden Betriebssystemen, Entwicklungsplatformen, physische Charaktersistika sowie Netzwerk Infrastrukturen ist ein in sich komplexes Oekosystem entstanden. Durch die Unterschiede der Systeme ist vorallem auf Seiten der Applikationsentwicker ein hoher Grad an Unsicherheit in Bezug auf die Entwicklungsstrategie entstanden was die Technologie und vorallem auch die Nachfrage betrifft. Das Ziel dieser Arbeit ist es ein “aggregiertes” Modell fuer die Distribution von Applikationen ueber mehrere Platformen zu finden. Im ersten Schritt wird die Analyse der existierenden Literatur in der Fachpresse, Internetquellen und Experteninterviews zum Thema Distributions- und Infrastrukturlandschaft in Form eines „Top-Down“ Ansatzes durchgefuehrt um eine Vergleichsbasis aufzubauen und eine Bewertung durchfuehren zu koennen. Im Folgenden wird die Modellierung der analysierten Geschaeftsprozesse mit dem ADONIS¼ Business Process Management Toolkit durchgefuehrt sowie fuer die Erstellung der Infrastrukturmodelle ADOit¼ IT Architecture- & Service Management Toolkit verwendet. Die daraus resultierenden Ergebnisse werden analysiert und gegen die „ideal“ Charakteristika verglichen und ein aggregiertes Modell erstellt. Im Anschluss wird der Ansatz eines aggregierten Models in Form der Meta Platform WAC getestet indem deren Entwicklungsumgebung fuer die Erstellung einer Beispielsapplikation verwendet und die Kompatibilitaet auf verschiedenen Platformen getestet wird.The mobile application market continues to grow drastically due to the explosion in the sales of mobile device. One of the drivers behind that increase is the development and penetration of application stores provided by different stakeholders in the mobile space especially handset manufacturers, operating system developers and network operators. Therefore handsets nowadays contain competing operating systems, development platforms and physical characteristics. This diversity leads to a large degree of uncertainty in the mobile space on a strategic, technological, and demand level for mobile application developers. Currently developers need to decide which platform to develop and distribute for. Decision factors include among others the target market, compatibility issue, development time, hardware requirements and scalability. This work provides an overview of the existing mobile application and app store market, investigating in business models, processes and infrastructures to develop and distribute mobile applications across multiple platforms. As the goal is to find an aggregated model for the distribution of cross-platform applications I will start with a top-down approach to identify the existing distribution and infrastructure landscape, therefore I will conduct a research of the literature, internet i.e. Application store developer sites, specialized press and expert talks. The modelling of the business processes will be done with ADONIS¼ Business Process Management Toolkit and the modelling of infrastructures with ADOit¼ IT Architecture- & Service Management Toolkit. The final part of the thesis describes the development of a sample application using the WAC environment and the compatibility of on different platforms will be tested

    Web-teknologiat kehitettiin alun perin kuvaamaan staattisten web-sivujen sisÀltöÀ. Web-selainten suosion vuoksi samoja teknologioita hyödynnetÀÀn nykyisin myös sovellusten toteuttamiseen kÀyttÀen web-selainta niiden suorittamiseen vuorovaikutteisesti. Web-teknologioiden suosiosta huolimatta ne sisÀltÀvÀt useita ongelmia ohjelmistojen toteuttamisen nÀkökulmasta. LisÀksi mobiililaitteiden rajoitukset tekevÀt kaikilla laitteilla toimivien sovellusten toteuttamisesta haasteellista. TÀmÀn vuoksi uusia ohjelmistoalustoja on kehitetty ratkaisemaan web-selainten asettamia rajoituksia. TÀssÀ diplomityössÀ koostetaan vaatimukset mobiililaitteissa toimiville web-sovelluksille.

Arviointi paljasti lukuisia haasteita, jotka liittyivÀt web-teknologioiden puutteelliseen ilmaisuvoimaan, yhteentoimivuuteen ja ohjelmistoalustan toiminnallisuuteen. TÀstÀ huolimatta esimerkkisovellus toteutti sille asetetut vaatimukset työpöytÀohjelmistotasoisesta toiminnallisuudesta.Web technologies were initially designed to facilitate the creation of static web pages. However, the ubiquity of the web browser has motivated the use of the same technologies as a basis for desktop-style applications which are executed within the web browser and have their characteristics such as high interactivity. Despite the popularity of web applications, there exists various problems due to the fact that established web technologies were not specified with applications in mind. In addition, the constraints introduced by mobile devices challenge the ubiquity of such applications. On this account, new platforms have emerged extending the capabilities of web browsers. In this thesis, the requirements for client-side web applications in mobile context are synthesized. Moreover, a taxonomy for web applications is drawn and client-side web technologies and major software platforms relevant to the client-side web applications are discussed. Furthermore, an application concept implementation developed using web technologies leveraging the capabilities of the major mobile platform is presented and evaluated against the defined requirements. The evaluation revealed various problems related to limited expressiveness of web technologies, interoperability and platform functionality. Regardless, the implementation provided a level of functionality comparable to that of native applications

    Thesis (Master)--Izmir Institute of Technology, Computer Engineering, Izmir, 2004Includes bibliographical references (leaves: 120)Text in English; Abstract: Turkish and Englishix, 133 leavesEnd-to-end security has been an emerging need for mobile devices with the widespread use of personal digital assistants and mobile phones. Transport Layer Security Protocol (TLS) is an end-to-end security protocol that is commonly used in Internet, together with its predecessor, SSL protocol. By using TLS protocol in mobile world, the advantage of the proven security model of this protocol can be taken.J2ME (Java 2 Micro Edition) has been the de facto application platform used in mobile devices. This thesis aims to provide an end-to-end security protocol implementation based on TLS 1.0 specification and that can run on J2ME MIDP (Mobile Information Device Profile) environment. Because of the resource intensive public-key operations used in TLS, this protocol needs high resources and has low performance. Another motivation for the thesis is to adapt the protocol for mobile environment and to show that it is possible to use the protocol implementation in both client and server modes. An alternative serialization mechanism is used instead of the standard Java object serialization that is lacking in MIDP. In this architecture, XML is used to transmit object data.The mobile end-to-end security protocol has the main design issues of maintainability and extensibility. Cryptographic operations are performed with a free library, Bouncy Castle Cryptography Package. The object-oriented architecture of the protocol implementation makes the replacement of this library with another cryptography package easier.Mobile end-to-end security protocol is tested with a mobile hospital reservation system application. Test cases are prepared to measure the performance of the protocol implementation with different cipher suites and platforms. Measured values of all handshake operation and defined time spans are given in tables and compared with graphs
