YRP Ubiquitous Networking Laboratory (YRP UNL for short) is a pioneer in the research field of what once was called ubiquitous computing and is now called the IoT.

This laboratory was established in 2002 to promote the collaborative research of industry and academia in this emerging field. As many of you know already, Yokosuka Telecom Research Park is an industrial park where many research laboratories of leading telecommunication companies in Japan are located. YRP UNL is a laboratory directly operated by Yokosuka Telecom Research Park, Inc. that manages the industrial park.


There are three major research groups at this laboratory. One is the aggregate computing group that studies and proposes the total architecture of ubiquitous computing. Second is the edge node research group that focuses on the IoT edge nodes, and leads the research on the world-renowned TRON architecture. And there is an application research group that studies applications that take advantages of the output of the other two groups.


The laboratory has become a focus of international collaboration efforts in the IoT field. For example, it acted as the coordinator on the Japanese side of an EU-Japan collaborative project on smart city that started in July 2017. One notable output from this laboratory is the contribution to the international standardization efforts. For example, a member of TRON Real-Time OS (RTOS) family has become an international standard, IEEE Standard for a Real-Time Operating System (RTOS) for Small-Scale Embedded Systems. ucode has become the basis of international standard at ITU-T (International Telecommunication Union Telecommunication Standardization Sector).

The laboratory has contributed to various application studies that use the basic architecture and related technologies so far. The wide dissemination of research results is another goal of the laboratory. Many research results have been published as academic papers, and the source codes of programs have been published based on the philosophy of open architecture.
