A DNS Architecture for the Internet of Things: A Case Study in Transport Logistics

Abstract

This paper proposes a DNS architecture for the Internet of Things (IoT). Similarly to the existing DNS infrastructure on the Internet, the DNS for the IoT translates unique identifiers (URIs) of physical objects to concrete network addresses, from which information about such objects (e.g. status, location) can be extracted. We propose an experimental DNS infrastructure for IoT, in the domain of transport logistics. We have simulated the behaviour of the DNS infrastructure using a 3 tier hierarchy of domain name servers and a three level caching strategy. Preliminary results indicate that a DNS approach could be a feasible proposition to realise object tracking in IoT.
