The ability to check the location of people or mobile devices (MD) in indoor environment has a large number of application. Indoor Positioning System (IPS) utilizes many existing technologies such as radio frequencies, magnetic fields, acoustic signals, thermal, optical or other sensors. WLAN IPS become one of the most favorite solutions because it is already widely exist and provide good accuracy...
With the emergence of Internet-of-Things (IoT) technologies, the application of Wireless Sensor Network (WSN) has become pervasive in our physical environment. These technologies rely on the WSN to capture environmental data and transmit it through the network to the specified location or storage. Given the massive data that captured by the WSN and the data transmission that happen in the process,...
Recently, there is high demand for implementing Location Based Services (LBS) indoor. Many technologies and methods have been investigated for this issue since GPS could not prove accurate positioning indoor. Although WLAN-fingerprinting is considered as one of the most accurate IPS method, its accuracy vulnerable to WLAN RSS fluctuation. This fluctuation occurs due to the physical obstacles presence...
Ubiquitous environments relies on the localization process of the mobile device or user. Although WLAN Received Signal Strength (RSS) fingerprinting is the most accurate indoor positioning method, it is a time consuming process and become impractical process for multi-floor environments. In addition to this any proposed method for floor determination in multi-floor environment must take into account...
Recently, an acoustic method is used in a water industry to detect and localise the leak in the water pipeline. However, the acoustic leak detection is only feasible for the metal pipes and has several limitations when applied to soft materials like plastic pipes. The objective of this paper is to investigate the accuracy of leakage detection for an Acrylonitrille Butadience Styrene (ABS) pipe using...
This paper presents a development of water pipeline monitoring system using vibration sensor. The MPU6050 sensor is selected to measure the vibration occurred along the pipes. In this study, the water pipeline used is high pressure pipe, an inch of the Acrylonitrille Butadience Styrene (ABS) pipe size with 10 meters length. The Arduino controller board then processes the vibration data from the accelerometer...
In order to enable Location Based Service (LBS) closed environment, many technologies have been investigated to replace the Global Positioning System (GPS) in the localization process in these indoor environments. WLAN occurs as the most suitable and powerful technology for Indoor Positioning System (IPS) due to its widespread and low cost. WLAN received signal strength (RSS) fingerprinting can be...
