    This document provides the description for the FYP project titled "job Searching Mobile Application using Location Awareness" .Location awareness is an important feature that could help the user to know the availability of job vacancy at their current location. However, the current job searching websites does not equip with this feature. Therefore, the objective of the research paper is to study how location awareness feature can be applied in job searching application using mobile computing as the platform. This mobile application was developed for Android Operating System, which it could help the user to search for part time job vacancy using location awareness feature. The location awareness features could be done in mobile application using the Global Positioning Technology (GPS) which it will detect the user's longitude and latitude. Subsequently, the longitude and latitude will be converted into strings and will be compared with the database. The data that match the database will be prompted to user. The mobile application has gone through the user acceptance test with 30 users has tested the software. Using Android, an open source operating system as the platform of the mobile application, it targeted the user with Android smart phone to benefit using this mobile application. As the conclusion, location awareness is a new feature that is relevant to job searching process and it has been proven with the development of this mobile application

    The assumptions made for target localization in wireless sensor network is not up to date. Restricted equipment assets, vitality protection and clamor disturbance because of remote channel dispute and instrumentation commotion make new limitations on originators these days. In the proposed paper target localization system which is based on TDOA is discussed. At the point when an event is identified, every sensor having a place with a gathering computes an estimation of the objective's area. A MAC convention for remote sensor systems i.e. Occasion Based –Medium Access Control (EB-MAC) is produced, which is adjusted for occasion based frameworks that portrays target confinement frameworks. Besides, EB-MAC gave a dependable correspondence stage where high channel conflict was brought down while keeping up high throughpu

    Mesh networks for handheld mobile devices

    Mesh communications emerge today as a very popular networking solution. Mesh networks have a decentralized and multihop design. These characteristics arouse interest in research for relevant novel features, such as cooperation among nodes, distribution of tasks, scalability, communication with limited infrastructure support, and the support of mobile devices as mesh nodes. In addition to the inexistence of a solution that implements mesh networks with mobile devices at the data link layer (Layer 2), there is also a need to reconsider existing metrics with new information to tackle the intrinsic characteristics of mobile devices, e.g., the limited energy resources of their battery. To tackle this problem, this thesis presents a detailed study about projects, routing protocols and metrics developed in the area of mesh networks. In addition, two data link layer solutions, Open802.11s and B.A.T.M.A.N-advanced, have been adapted and deployed in a real mesh network testbed with off the shelf routers devices installed with a customized operating system. From this testbed, Open802.11s has proved to offer better performance than B.A.T.M.A.N-advanced. Following this, a breakthrough in this work has been the integration of the 802.11s on an Android mobile device and its subsequent incorporation in the mesh network. This allowed the study of eventual limitations imposed by the mobile device on the operation of the mesh network, namely performance and energy scarcity. With this, another major novelty has followed, by designing, implementing and evaluating several energy related metrics regarding the battery status of mobile devices. This has enabled the participation of mobile devices in mesh routing paths in an efficient way. Our main objective was to implement a mesh network with mobile devices. This has been achieved and validated through the evaluation of diverse testing scenarios performed in a real mesh testbed. The obtained results also show that the operation of a mesh with mobile devices can be enhanced, including the lifetime of mobile devices, when an energy-aware metric is used.As redes mesh surgem hoje em dia como uma solução de rede em crescimento e expansão. Neste tipo de redes o comportamento entre os nós é descentralizado e numa topologia de multihop. Estas características despertam interesse na pesquisa e desenvolvimento de novas funcionalidades tais como: cooperação entre nós, distribuição de tarefas, escalabilidade da rede e comunicações mesmo em casos de uma infraestrutura limitada e o suporte de dispositivos móveis como nós de uma rede mesh. Associado à inexistência de um projecto que implemente redes mesh em dispositivos móveis na camada de ligação de dados (Layer 2), surge a necessidade de repensar as métricas já existentes com novas informações que façam face às novas características dos dispositivos móveis, neste caso, os recursos limitados de bateria. Por forma a resolver este problema, este trabalho apresenta um estudo detalhado sobre os projetos, protocolos de routing e métricas desenvolvidas na área das redes mesh. Além disso, duas soluções que utilizam a camada de ligação de dados, Open802.11s e BATMAN-advanced, estes foram adaptadao e implementados num testbed real utilizando routers com um sistema operacional costumizado instalado. Deste testbed, concluiu-se que o Open802.11s obtem um melhor desempenho que o BATMAN-advanced. Assim, um dos avanços deste trabalho foi a integração do Open802.11s num dispositivo móvel Android e sua posterior incorporação na rede mesh. Isto permitiu o estudo de eventuais limitações impostas pelo dispositivo móvel ao funcionar numa rede mesh, ou seja, desempenho e a escassez de energia. Com isso, foi concebida outra novidade, através da concepção, avaliação e implementação de várias métricas relacionadas com a energia e que têm por base o estado da bateria do dispositivo. Isto permitiu que os dispositivos móveis participem na rede mesh e a sua gestão de bateria seja feita de forma eficiente. O principal objectivo era a implementação de uma rede mesh com dispositivos móveis. Este foi alcançado e validado através de diversos cenários de teste reais. Os resultados obtidos demonstram também que o funcionamento de uma rede mesh com dispositivos móveis pode ser melhorada, incluindo o tempo de vida dos dispositivos móveis, quando uma métrica que considera a energia é utilizada

    A reminder plays an important role in every day life for everyone. People use various methods to remind themselves about daily tasks, events, meetings and etc. For example they use to-do list, stick notes, and date-time reminders in mobile phone. This research focuses on the development of location based reminder, a method of reminding people deployed on mobile phones. It implements the concept of context-aware in ubiquitous and is supported by location detection by GSMtechnologies. The project, L-Minder, will be an upgraded version of the existing time and date based reminder because of the location awareness and context awareness. The reminder will remind the users about the daily tasks, events, meetings and etc based on the desired location at which these events or tasks needed to be performed. Intensive research and literature review had been done in order to obtain as much useful information data to develop the project. Surveys had been done over a specific group of users to obtain dataon preferences, dislikes and other important information regarding the development of the system. The project will solve many problems that arise from both time and date based reminder and the existing location based reminders in the market

    This paper presents a context-aware guidance and messaging system for large buildings and surrounding venues. Smart Signs are a new type of electronic door- and way-sign based on wireless sensor networks. Smart Signs present in-situ personalized guidance and messages, are ubiquitous, and easy to understand. They combine the easiness of use of traditional static signs with the flexibility and reactiveness of navigation systems. The Smart Signs system uses context information such as user’s mobility limitations, the weather, and possible emergency situations to improve guidance and messaging. Minimal infrastructure requirements and a simple deployment tool make it feasible to easily deploy a Smart Signs system on demand. An important design issue of the Smart Signs system is privacy: the system secures communication links, does not track users, allow almost complete anonymous use, and prevent the system to be used as a tool for spying on users
