An ICN system focusing on distributed MQTT Brokers for IoT services

Network technologies for the Internet of Things (IoT) have been widely discussed for real time deployment. In the IoT services, a huge number of small packets are transferred across the networks. If the current Internet technologies are applied to these services, a large overhead is caused by the IP routing process, information discovery, and large protocol headers, such as HTTP over TCP. In addressing this problem, the application of Information Centric Network (ICN) technologies to the IoT services holds promise. However, this has a disadvantage in that a network based on the ICN technologies is expanded to a larger area. This study proposes a solution to this problem through a framework of a distributed ICN system for the IoT services. In the proposed approach, the end points are invoked by the ICN related protocols. Interworking points are invoked to connect among themselves by a logical loop and cached information is transferred in real time through “shared memory architecture”. This study also presents the detailed operations based on this approach.
