Implementation of a KNX-ZigBee gateway for home automation

The demand for wireless technology in home automation systems has recently been increasing due to several advantages such as installation cost reduction, easy placement, easy extension, aesthetic benefits, and mobile device connectivity. Among the many wireless technologies available, ZigBee is one of the most useful for home automation. A wireless home networking system can be configured using ZigBee alone. However, compatibility with conventional networking systems based on wired media is not supported. KNX is a mature protocol for wired media and is recognized as an international standard. In this paper, a KNX-ZigBee gateway is proposed for interfacing between KNX and ZigBee systems, thereby enabling the integration of wired and wireless home automation systems.
