An SDN-Based Distributed Identifier Locator Separation Scheme for IoT Networks

In the Internet of Things (IoT) environments, sensor devices need to be connected to the networks for data transmission and inter-communication with machine to machine, machine to human. Most devices connected to the network need a distinguishable identifier and a network address, therefore, IP address is the best solution for that. However, due to the constraints of sensor devices, it is hard to deploy on legacy IP system directly. To solve this issue, a concept for the separation of identifier and locator from the IP address is able to be the alternative. From the viewpoint of the addressing separation, we propose an SDN-based identifier locator separation architecture for IoT networks with distributed manner.
