    Accessing information quickly has become more and more important. Mobile devices can nowadays be used to perform and accomplish tasks more efficiently. Logistics companies can benefit from mobile applications in many ways. Many logistics areas, such as warehouse managing and transportation, concentrate on the physical movement of goods. The benefits of mobile applications are emphasised in those environments where portability and real-time information are of great use. The business IT alignment framework offers an approach to researching companies business and IT strategies and execution. The enterprise mobile applications may bring many advantages but also disadvantages to organisations utilising them. In this thesis, the business It alignment framework is used in the context of researching the utilisation of enterprise mobile applications in the case organisations. The utilisation of mobile applications in logistics is studied in this research by using the qualitative research method. Research data has been gathered from semi-structured interviews with case company employees responsible for logistics mobile application projects. The logistics areas where mobile applications are used are warehouse management and transportation. A new logistics IT alignment measurement tool was developed for the purposes of this study, as no such a tool existed before. The tool utilises the previous business IT alignment literature. Companies or researchers can utilise this tool in determining their logistics IT alignment level. This study finds that there are multiple important features that companies should take into account when developing and implementing logistics mobile applications. Ease of use and user friendliness are the most important of them. In addition, information quality and efficiency and effectiveness should be considered. Many companies also benefit from end device independence. Companies can get many advantages from logistics mobile applications. These advantages are for example better information quality, real-time information and cost reductions by consuming less paper. High logistics IT alignment supports in gaining these advantages

    Autonomous navigation is a traditional research topic in intelligent robotics and vehicles, which requires a robot to perceive its environment through onboard sensors such as cameras or laser scanners, to enable it to drive to its goal. Most research to date has focused on the development of a large and smart brain to gain autonomous capability for robots. There are three fundamental questions to be answered by an autonomous mobile robot: 1) Where am I going? 2) Where am I? and 3) How do I get there? To answer these basic questions, a robot requires a massive spatial memory and considerable computational resources to accomplish perception, localization, path planning, and control. It is not yet possible to deliver the centralized intelligence required for our real-life applications, such as autonomous ground vehicles and wheelchairs in care centers. In fact, most autonomous robots try to mimic how humans navigate, interpreting images taken by cameras and then taking decisions accordingly. They may encounter the following difficulties

    Abstract:-Context based Mobile Information Catalog Surveillance is a mobile phone based communication application.The Short Message Service (SMS) allows text-based messages to be send from mobile telephones on a GSM network. .Many applications need the ability to do real-time notification when events occur. Often the people who need to be kept aware of events are in a remote location. Here the same is to giving the notification to the user when ever they want to communicate with their mobile virtually.To find the contact log from the Android mobile devices whenever we required the contact and change the profile mode of the device for our convenient. This application proved to get the recent call logs details when you sent a message to the device. Then you may want to see contact list those which are think from your mind alphabetical contacts you can get from your mobile. And you change the profile mode for your mobile and if you want Switch off your mobile you can. It is used on Business point of view surveillance and Security. Real time example if the user forgot his mobile at his home and context is very important to access the last moment data received by his mobile. Here context is nothing but the surrounding situation. If you need business point of view you need to access the last moment message otherwise to access the recent call logs which may be important or you need to access the contacts in alphabetical order. In that situation you need to give a privacy to your mobile device you can change your mobile to change the profile mode or to lock the screen. If suppose in your mobile is in silent mode you need anybody to want to access your mobile in your mobile surroundings you can change the mobile device into the normal mode.

    Enhancing Quality of Service (QoS) in mobile networks is the key aim for mobile operators. Mobile networks transport several forms of data traffic for real-time applications (i.e., video monitoring). These applications need to get the advantage of QoS adaptation. Numerous scheduling techniques are utilized at the router to assure the QoS of the mobile networks. Upcoming 5G mobile networks will be launched; hence, Human-Type-Communication (HTC) and Machine-to-Machine (M2M) data traffic are expected to increase dramatically over mobile networks, which results in growing the capacity and raising high data rates. These networks are expected to face challenges in cases of Radio Access Network (RAN) overload and congestion due to the massive smart devices data traffic with various QoS requirements. This paper presents a comparison for data traffic scheduling techniques, which are Priority Queuing (PQ), First-In-First-Out (FIFO) and Weighted Fair Queuing (WFQ). We consider to select a suitable data traffic scheduling technique in terms of QoS provisioning and helping 5G network, also we propose models and algorithms for efficiently utilized the smallest unit of a RAN in a relay node by aggregating and slicing the data traffic of several M2M devices

    Telecommunications have an important role in facilitating communication and information exchange, especially in emergency situations such as natural disasters and unexpected community events. Implementing mobile technology is a promising solution to improve the response and handling of in-kind problems. Mobile technology allows the public to quickly report incidents of disaster or security issues through applications or short message services. The implementation of mobile technology facilitates real-time communication between the community and Babinsa. The public can send reports quickly, convey important information, and share photos or videos as evidence of events. Babinsa, on the other hand, can respond more efficiently to these reports and take necessary actions based on the information received. Apart from that, mobile technology also supports two-way communication between Babinsa and the community. The public can also get the latest information about emergencies, efforts handling, or evacuation via app or direct message notification. Thus, the implementation of mobile technology can make a significant contribution to improving communication, response, and handling of disasters and community events

    Entity Localization and Tracking: A Sensor Fusion-based Mechanism in WSNs

    International audienceKnowing exactly where a mobile entity is and monitoring its trajectory in real-time has recently attracted a lot of interests from both academia and industrial communities, due to the large number of applications it enables; nevertheless, it is nowadays one of the most challenging problems from scientific and technological standpoints. In this work we propose a tracking system based on the fusion of position estimations provided by different sources, that are combined together to get a final estimation that aims at providing improved accuracy with respect to those generated by each system individually. In particular, exploiting the availability of a Wireless Sensor Network as an infrastructure, a mobile entity equipped with an inertial system first gets the position estimation using both a Kalman Filter and a fully distributed positioning algorithm (the Enhanced Steepest Descent, we recently proposed), then combines the results using the Simple Convex Combination algorithm. Simulation results clearly show good performance in terms of the final accuracy achieved. Finally, the proposed technique is validated against real data taken from an inertial sensor provided by THALES ITALIA

    A Framework for Model-Driven Development of Mobile Applications with Context Support

    Get PDF
    Model-driven development (MDD) of software systems has been a serious trend in different application domains over the last 15 years. While technologies, platforms, and architectural paradigms have changed several times since model-driven development processes were first introduced, their applicability and usefulness are discussed every time a new technological trend appears. Looking at the rapid market penetration of smartphones, software engineers are curious about how model-driven development technologies can deal with this novel and emergent domain of software engineering (SE). Indeed, software engineering of mobile applications provides many challenges that model-driven development can address. Model-driven development uses a platform independent model as a crucial artifact. Such a model usually follows a domain-specific modeling language and separates the business concerns from the technical concerns. These platform-independent models can be reused for generating native program code for several mobile software platforms. However, a major drawback of model-driven development is that infrastructure developers must provide a fairly sophisticated model-driven development infrastructure before mobile application developers can create mobile applications in a model-driven way. Hence, the first part of this thesis deals with designing a model-driven development infrastructure for mobile applications. We will follow a rigorous design process comprising a domain analysis, the design of a domain-specific modeling language, and the development of the corresponding model editors. To ensure that the code generators produce high-quality application code and the resulting mobile applications follow a proper architectural design, we will analyze several representative reference applications beforehand. Thus, the reader will get an insight into both the features of mobile applications and the steps that are required to design and implement a model-driven development infrastructure. As a result of the domain analysis and the analysis of the reference applications, we identified context-awareness as a further important feature of mobile applications. Current software engineering tools do not sufficiently support designing and implementing of context-aware mobile applications. Although these tools (e.g., middleware approaches) support the definition and the collection of contextual information, the adaptation of the mobile application must often be implemented by hand at a low abstraction level by the mobile application developers. Thus, the second part of this thesis demonstrates how context-aware mobile applications can be designed more easily by using a model-driven development approach. Techniques such as model transformation and model interpretation are used to adapt mobile applications to different contexts at design time or runtime. Moreover, model analysis and model-based simulation help mobile application developers to evaluate a designed mobile application (i.e., app model) prior to its generation and deployment with respected to certain contexts. We demonstrate the usefulness and applicability of the model-driven development infrastructure we developed by seven case examples. These showcases demonstrate the designing of mobile applications in different domains. We demonstrate the scalability of our model-driven development infrastructure with several performance tests, focusing on the generation time of mobile applications, as well as their runtime performance. Moreover, the usability was successfully evaluated during several hands-on training sessions by real mobile application developers with different skill levels
