Job Searching Mobile Application using Location Awareness
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

DIY networking as a facilitator for interdisciplinary research on the hybrid city
DIY networking is a technology with special characteristics compared to the public Internet, which holds a unique potential for empowering citizens to shape their hybrid urban space toward conviviality and collective awareness. It can also play the role of a “boundary object” for facilitating interdisciplinary interactions and participatory processes between different actors: researchers, engineers, practitioners, artists, designers, local authorities, and activists. This position paper presents a social learning framework, the DIY networking paradigm, that we aim to put in the centre of the hybrid space design process. We first introduce our individual views on the role of design as discussed in the fields of engineering, urban planning, urban interaction design, design research, and community informatics. We then introduce a simple methodology for combining these diverse perspectives into a meaningful interdisciplinary collaboration, through a series of related events with different structure and framing. We conclude with a short summary of a selection of these events, which serves also as an introduction to the CONTACT workshop on facilitating information sharing between strangers, in the context of the Hybrid City III conference
Increasing Throughput by Efficient Target Localization in WSN
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
Location Based Reminder System: L-Minder System
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
Smart Signs: Showing the way in Smart Surroundings
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
