This paper presents a research and a development of a fingerprint-indoor-positioning system using the Received Signal Strength Indication (RSSI) of a Wireless Sensor Network (WSN). The WSN implementation is based on two different protocol stacks: BitCloud and OpenMAC, a certified ZigBee Compliant Platform (ZCP) and an IEEE 802.15.4 embedded software implementation respectively, both from Atmel,...

Manual fingerprint classification algorithms are very time consuming, and usually not accurate. Fast and accurate fingerprint classification is essential to each AFIS (Automatic Fingerprint Identification System). This paper investigates a fingerprint classification algorithm that reduces the complexity and costs associated with the fingerprint identification procedure. A new structural algorit...

ZigBee technology is a kind of wireless technology with short distance, low complexity, low power consumption, low data rate, low cost and wireless network technology. Smart Home system consists of the system server, the family controller (modules), the composition of routers, switches, communication device, controller, wireless transceiver, all kinds of detectors, sensors, actuators and other ...

We are investigating the fingerprint method using wireless LAN access points (APs) to estimate user location. focused on database update as a way prevent loss of localization accuracy. Updating user-measured data presents issue errors. In this paper, we have proposed and verified issues.

Fingerprint-based methods are widely adopted for indoor localization purpose because of their cost-effectiveness compared to other infrastructure-based positioning systems. However, the popular location fingerprint, Received Signal Strength (RSS), is observed to differ significantly across different devices’ hardware even under the same wireless conditions. We derive analytically a robust locat...

Nowadays, there is a great interest in developing accurate wireless indoor localization mechanisms enabling the implementation of many consumer-oriented services. Among the many proposals, wireless indoor localization mechanisms based on the Received Signal Strength Indication (RSSI) are being widely explored. Most studies have focused on the evaluation of the capabilities of different mobile d...

Authentication is one of the major challenges to access these web applications. With varying level of sensitive data stored in web ...

Wireless signal strength is susceptible to the phenomena of interference, jumping, and instability, which often appear in the positioning results based on Wi-Fi field strength fingerprint database technology for indoor positioning. Therefore, a Wi-Fi and PDR (pedestrian dead reckoning) real-time fusion scheme is proposed in this paper to perform fusing calculation by adaptively determining the ...

Our B. Tech. Project aims at introducing biometric capable technology for use in automating the entire attendance system for the students pursuing courses at an educational institute. The goal can be disintegrated into finer sub-targets; fingerprint capture & transfer, fingerprint image processing and wireless transfer of data in a server-client system. For each sub-task, various methods from l...
