Bridging light applications to the IP domain

With the advent of LED lights as well as lighting systems that have communication capabilities, new lighting setups and scenarios have become possible. New standards of the ZigBee Cluster Library (ZCL) in lighting systems describe the protocols for controlling and monitoring devices in such systems. In this paper we examine the problem of bridging this ZigBee domain to the IP domain such as allowing standardized access and easy integration of advanced lighting scenarios. We define two access levels for the bridging: a message-based API, which translates the protocol and which allows integration in arbitrary networked environments and an HTTP interface that gives access to an embedded web application for direct control purposes. We show a realization of this design on a prototype board of ZigBee and IP modules along with measurements on response times.
