There is high expectation towards the changes that come with the implementation of the Internet

of Things (IoT). However, this vision is limited by the heterogeneous nature of IoT devices. This led to

vertical application silos that are incapable of working together. To ease this problem of heterogeneity, we

have developed a lightweight interoperability framework, LISA, to hide variations in communication

technology and data formats and provide a uniform API for programmers. LISA is inspired by Network on

Terminal Architecture (NoTA), an open framework from Nokia Research Center. There are few

frameworks for interoperability of IoT. However, these frameworks fail to address the resource limitations

of the majority of IoT devices. To the best of our knowledge, LISA is the first framework designed for

resource constrained devices. This demonstration shows LISA in action, helping heterogeneous devices

interoperate through a gateway in the fog layer between the devices and the cloud.
