IoT based localization and tracking

Internet of Things (IoT) has several applications which directly affect our lives. IoT has been proposed to be part of the connected living paradigm. In this pool of applications, we also have localization based services. In the first one, localization of objects, animals and other living beings are determined using IoT. In the second one, the movement of the animals, kids, elderly and other moveable objects are tracked. Both localization and tracking are part of security and surveillance services in the connected living environments. In this paper, we provide the current state of the art for IoT based localization and tracking. We show the key technical aspects, compare the IoT based initiatives for localization with the non-IoT based services and finally show their utilities in different application domains. IoT based localization and tracking are found to be more pervasive and accurate than the previously used techniques.
