A Survey in Localization Techniques Used in Location-based Access Control

Abstract

There has been a huge growth in the number of mobile devices in the last few years. These mobile devices are equipped with various hardware that allows them to sense and receive different types of wireless signals such as Global Positioning System (GPS), Wi-Fi, Bluetooth, and others. Today, a mobile device is capable of obtaining its location in various ways. Location-enabled mobile devices enable applications to utilize and verify users' location to allow them to access location-based resources, which is known as Location-based access control (LBAC). The implementation of LBAC has grown rapidly with the increase in the number of mobile devices and location-based services (LBS) and is expected to grow more in the future. LBAC verifies the user's location is required. User location can be obtained using different localization techniques. In this paper, we survey the localization techniques used in LBAC. Consequently, we examine and review the strength and weaknesses of each of the localization techniques. Finally, we discuss the nature of applications that suits each localization technique the most.
