Among techniques designated for indoor localization, wireless fingerprinting is the most emerging because of the widespread deployment of wireless networks. Moreover, positioning methods based on received signal strength indicator fingerprint are attractive for their accuracy and independence from the radio propagation model. This paper describes an implementation of Bluetooth Low Energy positi...

Biometric identification is an emerging subject in applications like high-security wireless access and secure transactions across computer networks. Fingerprints are easy to use and provide relatively good performance. Furthermore, fingerprint sensors are cheap and can be integrated easily in wireless hardware. In this paper, methods are presented for the estimation of a high resolution directi...

Supply chain management requires regular updates of the location of assets, which can 3 be enabled by low power wide area networks, such as Sigfox. While it is useful to localize a device 4 simply by its communication signals, this is very difficult to do with Sigfox because of wide area 5 and ultra narrowband nature. On the other hand, installing a satellite localization element on the 6 devic...

The Received Signal Strength (RSS) fingerprint-based indoor localization is an important research topic in wireless network communications. Most current RSS fingerprint-based indoor localization methods do not explore and utilize the spatial or temporal correlation existing in fingerprint data and measurement data, which is helpful for improving localization accuracy. In this paper, we propose ...

In this paper we design a system which takes student attendance and the attendance records are maintained automatically in an academic institute. Taking the attendance manually and maintaining its record till end of year (or even beyond) is very difficult job as well as wastage of time and paper. This necessitates an efficient system that would be fully automatic. Top level design of the system...

In wireless sensor networks there is a need to securely store monitored data in a distributed way whenever it is either not desired or simply not possible to transmit regional volatile information to an authorised recipient in real-time. In particular, for wireless sensor network applications with an asynchronous character, the wireless sensor network itself needs to store the monitored data. S...
