Interworking of oneM2M-based IoT systems and legacy systems for consumer products

The emerging Internet of Things (IoT) market and ecosystem will be fragmented due to heterogeneous systems and standards, which is often considered as one of the main challenges in the IoT research. The oneM2M initiative established in 2012 has been working on tackling such a fragmentation problem of IoT standards, and finally released its first specifications in January 2015. In particular, it defines a way of interworking oneM2M and non-oneM2M systems based on interworking proxy entity (IPEs). In this paper, we illustrate the implementation of oneM2M IPE for interworking with legacy systems of consumer products, including Nest thermostat, Jawbone fitness tracker, and Withings blood pressure monitor. The implemented IPE works well with the chosen products, and several interworking scenarios were successfully demonstrated at the oneM2M Showcase hosted by TIA (Telecommunications Industry Association) in Dallas, TX, U.S. in June 2015.
