With the wide deployment of Wi-Fi networks, Wi-Fi based indoor localization systems that are deployed without any special hardware have caught significant attention and have become a currently practical technology. At the same time, the Magnetic, Angular Rate, and Gravity (MARG) sensors installed in commercial mobile devices can achieve highly-accurate localization in short time. Based on this,...

Simultaneous Authentication of Equals (SAE) is a password-authenticated key exchange protocol that designed to replace the WPA2-PSK-based authentication. The SAE authenticated supports peer-to-peer authentication and one major mechanisms Key Management Suite specified within Wi-Fi. has been widely implemented in today’s Wi-Fi devices as part security feature upgrades regarded third generation P...

As it is known, to provide fire protection for any type of surface vessel, external fire-fighting (EFF) systems have been commonly used decades as well in coastal regions. These types exist on several vessels such ships, tugboats, supply and naval vessels. Flow conditioners can be the EFF better performance by regulating flow inside fi-fi monitor. In present study, a (fi-fi) monitor was designe...

This study aims to design and develop Wi-Fi tracker system that utilizes RSSI-based distance parameters for crowd-monitoring applications in indoor settings. The consists of three main components, namely 1) an embedded node runs on Raspberry-pi Zero W, 2) a real-time localization algorithm, 3) server with online dashboard. scans collects relevant information from Wi-Fi-connected smartphones, su...

Many context-aware mobile applications require a reasonably accurate and stable estimate of a user’s location. While the Global Positioning System (GPS) works quite well world-wide outside of buildings and urban canyons, locating an indoor user in a real-world environment is much more problematic. Several different approaches and technologies have been explored, some involving specialized senso...

The paper focuses on the real-world usage of IEEE 802.11 wireless network encryption and Wi-Fi Protected Setup (WPS) function. A brief history on the development of encryption methods and WPS is given. Wireless scanning of 802.11 networks in a capital city has been performed, and the results of it have been analysed. To ascertain the knowledge about the security of wireless networks of the aver...
