Localization in IoT- A Review

We are witnessing the dawn of a new era of Internet of Things. With the development in various technologies, the internet of things has been widely used in building smart cities and homes. There are various challenging issues in IoT like routing, addressing, localization and so on. Localization is one of the key issues which needs to be taken into account. Many localization algorithms and systems have been developed by means of wireless sensor networks for both indoor and outdoor environments. This paper reviews various localization algorithms designed for IoT systems. With the increasing demand of smart objects in our everyday life promotes an advance generation of communications under the umbrella of the Internet of Things (IoT). For IoT, location-based service is one of the main services, while localization accuracy is a primary problem.
