A Proposal on “Sandwich” Architecture in the Communication Platform for IoT Services
2023
In the mature stage of IoT, the horizontal approach is focused.For this purpose, the IoT platform with the commonality of functions should be deployed.However, the IoT platform has various options.This paper surveys the IoT reference model, and clarifies the IoT platform that complies with the reference model.Then, this paper proposes that two communication platforms should be deployed, i.e., the application layer including Information Centric Network (ICN) technologies, and datalink/physical layer platforms, including Passive Optical Network (PON) technologies.It also proposes that the Internet should be put between these platforms like "Sandwich."This paper denominates this layered architecture as "Sandwich architecture.
