A Survey on Localization in Internet of Things: Techniques, Approaches, Technologies and Challenges

In present scenario, the Internet of Things (IoT) has rapidly become a major use in people’s modern life. A network defines number of heterogeneous devices using a single communication like Wi-Fi, Bluetooth etc. In today’s real world, there are many ways to connect with the IoT object. IoT uses many technologies like Wi-Fi, GPRS, 5G etc. for identifying the location of an object. The objects can be of different categories like any device, home appliances, vehicle, building, machines etc. It is difficult to communicate with these objects using above technology either we are live in smart building or in smart cities. The major challenges in indoor is the presence of small obstacles, as of which finding the accurate location of an object is difficult compare to outer localization. So many algorithms developed for localization in both indoor and outdoor environment.
