Abstract
The existence of mobile devices as a location pointing device using Global Positioning System (GPS) is a very common thing nowadays. The use of GPS as a tool to determine the location of course has a shortage when used indoors. Therefore, the used of indoor location-based services in a room that leverages the use of Access Point (AP) is very important. By using the information of the Received Signal Strength (RSS) obtained from AP, then the location of the device can be determined without the need to use GPS. This technique is called the location fingerprint technique using the characteristics of received RSS’s fingerprint, then use it to determine the position. To get a more accurate position then authors used the K-Nearest Neighbor (KNN) method. KNN will use some of the data that obtained from some AP to assist in positioning the device. This solution of course would be able to determine the position of the devices in a storied building.
Highlights
The abundance of location-based services that thrive in this era relies heavily on the ability of the use of the Global Positioning System (GPS) [1, 2]
This research begins with the authors collecting Access Point (AP) data, and room data that exist in a building that will be used as a place of research as well as the author performs a training phase on the prototype of the application that has been made
The results of the Received Signal Strength (RSS) fingerprint method implementation and K-Nearest Neighbor (KNN) method show that the mobile-based (CAPTURE) wireless positioning system can recognize the indoors location properly by using the wireless 802.11b/g technology
Summary
The abundance of location-based services that thrive in this era relies heavily on the ability of the use of the Global Positioning System (GPS) [1, 2]. One technology that can be utilized to recognize indoor locations is by using wireless technology (for example, using WIFI) contained within a building [4, 5]. The method of determining location using wireless network can be done more quickly and be more efficient use of power source. It is said to be more efficient because when compared with other methods, the method of using WIFI network uses less information so that the resources to the cost used was not too big when compared to the use of GPS technology [6, 7]. There are many ways to determine the position in indoor environment, by utilizing 802.11 b/g Wireless Local Area Network (WLAN) technology, Bluetooth, Radio Frequency Identification (RFID) and the others [8]. In many ways to determine position at indoor environment, the RSS fingerprint method is one of the most popular iJIM ‒ Vol 12, No 1, 2018
