Localization Techniques in the Future IoT: A Review

Dramatic developments in localization techniques have been achieved recently to overcome the difficulties of the Internet of Things (IoT) paradigm. The diversity of IoT in nearly all sectors, which requires the connection among objects, makes localization an important aspect in the field as it adds to the features of IoT. Precisely estimating the position of an object is one of the main purposes of localization to facilitate the exchange of information among the objects. The aim of this work is to explore the existing localization techniques and to evaluate existing encapsulating classification systems. For the literature survey, we have searched in all major databases. Relevant papers (amongst more than hundreds of the papers) are considered and evaluated to contribute to this work. In conclusion, the presented survey will assist people who are working in the field of localization in IoT and different related methods.
