The proposed architecture is based on RF4CE which has a reliable sandard enhances the IEEE 802.15.4 standard by providing a simple networking layer and standard application profiles that can be used to create a multi-vendor interoperable solution for use within the home. We develop H/W prototype and demonstrate verification scenarios using RF4CE-based Wireless Auto Configuration (REWACON) architecture.

4. 4 Introduction(1/3) Recently, the RF4CE (Radio Frequency for Consumer Electronics) industry consortium has been formed to develop a new protocol for the adoption of radio frequency remote controls for audio visual devices. The consortium founding members, Panasonic, Philips, Samsung Electronics and Sony Corporation have been working together with chip vendors such as Freescale Semiconductors, OKI, and TI to create a standardized specification for radio frequency- based remote controls.

It is supported by IEEE 802.15.4 as like Zigbee but simpler than Zigbee Stack. Its major characteristics include 1) No line-of-sight or field of vision limitations, 2) Bi-directional capability, 3) Faster more reliable communications, 4) less power consumption,5) true interoperability between vendors’ products.

9. 9 In case of RF4CE topology, the ZigBee RF4CE network is composed of two types of device: a target node and a controller node. A target node has full PAN coordinator capabilities and can start a network in its own right.

A controller node can join networks started by target nodes by pairing with the target. Background Work(3/5)

10. 10 Multiple RC PANs form an RC network and nodes in the network can communicate between RC PANs. In order to communicate with a target node, a controller node first switches to the channel and assumes the PAN identifier of the destination RC PAN. It then uses the network address, allocated through the pairing procedure, to identify itself on the RC PAN and thus communicate with the desired target node. Background Work(4/5)
