Atualmente é difícil encontrar um lugar que não ofereça acesso à internet, seja residencial, comercial ou espaço público, visando a mobilidade muitos destes pontos de acesso são sem fio o que os torna vulneráveis a ataques visando a obtenção ilegal de dados por terceiros, esta possibilidade está primariamente ligada a forma em que o ponto de acesso foi instalado e configurado em primeiro lugar. O objetivo deste trabalho é a analisar possíveis falhas em ambientes de redes sem fio, e como é importante conhecer os principais aspectos que a englobam a sua segurança, tais como: O funcionamento dos protocolos de segurança, A segurança física de um ponto de acesso, e os métodos mais comuns utilizados para tentativas de invasão para que seja possível informar satisfatoriamente um usuário novo no assunto. O tipo de pesquisa a ser realizado neste trabalho será uma Revisão de Literatura, com consultas realizadas á livros, documentos oficiais, sites da internet, revistas e artigos científicos publicados nos últimos 20 anos.

Cleaning is essential one to make the environment sanitary. This work deals with design and fabrication of automatic floor cleaning machine. Here in this project, we reducing the vibration that produced by motors in machine during cleaning process. And reduce the cleaning time to save the time and reducing the human effort to make the environment clean. And also providing the easy way of Bluetooth control system to control the machine effort less. The machine cleans the 100 m 2 room within 18 min both sweeping and wet moping operations with the speed of 0.51 km/hr. The purpose of this project is to clean the floors in hospitals, malls, auditoriums etc.

"As wireless technology continues along its path of evolution, new capabilities are constantly introduced in the form of innovative wireless business applications. These emerging wireless applications present a value proposition that targets previously ignored or less efficiently addressed areas of interest for either consumers or businesses. This is the mandate for Mobile Commerce (mCommerce). With increasing penetration rates for wireless devices and a growing  acceptance (by both consumers and businesses) of m-Commerce for enabling fulfillment of desired functions, niche segments are constantly being investigated and qualified for fit with wireless technology. The health care sector appears to be one such niche segment that is poised to benefit by adopting wireless solutions. The use of wireless devices and corresponding wireless applications in health care is commonly referred to as mobile health (m-Health). M-Health proposes to radically change the way health care is currently conducted, as wireless technology enhances the quality of patient care, but also yields operational efficiencies within the health care industry. This paper attempts to provide an overview of m-Health.
We start with an introduction of m-Commerce and an examination of its key characteristics. An overview is presented of the Health Care market landscape, followed by a discussion of the value proposition that m-Health creates. Needs addressed and challenges faced by implementing m-Health initiatives are then examined. The paper ends with a review of m-Health applications, some conclusions, and potential directions for future research."

In Schools and mostly in colleges taking attendance of the students is the most crucial task for the faculties because it has the major chances of doing proxies. We have Identified the complexities and brought latest technology for teachers to take the attendance of the students through wireless fingerprint attendance management system using zigbee. Our system will efficiently reduce the workload on teachers for uploading the attendance, storing lots of papers to maintain attendance record, making the defaulter list etc. This will efficiently reduce the errors made by the faculties at the time of uploading the attendance in the system.

In this paper a voice controlled wireless smart home system has been presented for elderly and disabled people. The proposed system has two main components namely (a) voice recognition system, and (b) wireless system. LabView software has been used to implement the voice recognition system. On the other hand, ZigBee wireless modules have been used to implement the wireless system. The main goal of this system is to control home appliances by using voice commands. The proposed system can recognize the voice commands, convert them into the required data format, and send the data through the wireless transmitter. Based on the received data at the wireless receiver associated with the appliances desired switching operations are performed. The proposed system is a low cost and low power system because ZigBee is used. Additionally the proposed system needs to be trained of voice command only once. Then the system can recognize the voice commands independent of vocabulary size, noise, and speaker characteristics (i.e., accent).

Remote health care monitoring system (RHCMS) has drawn considerable attentions for the last decade. As the aging population are increasing and at the same time the health care cost is skyrocketing there has been a need to monitor a patient from a remote location.  Moreover, many people of the World are out of the reach of existing healthcare systems. To solve these problems many research and commercial versions of RHCMS have been proposed and implemented till now. In these systems the performance was the main issue in order to accurately measure, record, and analyze patients’ data. With the ascent of wireless network RHCMS can be widely deployed to monitor the health condition of a patient inside and outside of the hospitals. In this work we present a ZigBee based wireless healthcare monitoring system that can provide real time online information about the health condition of a patient. The proposed system is able to send alarming messages to the healthcare professional about the patient’s critical condition. In addition the proposed system can send reports to a patient monitoring system, which can be used by the healthcare professionals to make necessary medical advices from anywhere of the World at any time.

Anomaly detection in wireless sensor networks is an important challenge for tasks such as fault diagnosis, intrusion detection, and monitoring applications. The algorithms developed for anomaly detection have to consider the inherent limitations of sensor networks in their design so that the energy consumption in sensor nodes is minimized and the lifetime of the network is maximized. In this survey article we analyze the state of the art in anomaly detection techniques for wireless sensor networks and discuss some open issues for research.

A wireless instrumentation system was successfully developed and tested to overcome the constraints associated in collection of torque data of PTO-driven agricultural machinery with benefits such as no disturbance in telescopic action or vertical inclination of Cardan shaft. The system ensured no alterations in standard length of PTO driveline shaft. Further, telemetry system enabled remote acquisition of signals without inducing any risk of damaging the associated electronic components. It offered sensitivity of 1.6 mV/V per kN-m of applied torque with good linearity during static calibration. The performance was assessed based on accuracy, non-linearity, hysteresis, and non-repeatability and their values were 97.06%, 2.57%, 3.44%, and 0.26%, respectively. The data obtained for torque were validated with the torque computed from axial and radial load data of PTO ball bearing acquired simultaneously during rotary tillage. The low values of mean absolute percentage error (7.78% and 6.58%), maximum absolute variation (15.17% and 15.39%), and root mean square error (21.24 and 22.16 N-m), indicated good accuracy of the system. The experiments were designed with active tillage tools having two different numbers of blades, transmission gear ratios, engine speeds, tyre sizes, and four working depths as treatments. Results revealed that considered variables other than tire size, significantly affected the PTO torque and power. The decrease in PTO torque and power was found to be levelled off beyond velocity ratio 7.92. The developed instrumentation technique is simple, reliable and could be useful for database generation, implement design, and matching for effective utilization of tractor engine power.
