AbstractAbstract

This paper is to present a new novel architecture to provide smart and easy control and sharing between various CE and IT devices.

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.

Introduction(1/3)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.

Introduction(2/3)Introduction(2/3)

Also, working with Zigbee Alliance, it aims to deliver richer communication, increased reliability and more flexible use. 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 .

Introduction(3/3)Introduction(3/3) In this paper, we address the RF4CE-based Wireless Auto Configuration (REWACON) architecture in order to provide easy control and contents sharing in ubiquitous smart home service.

To help understand the REWACON architecture, we apply TV and PC as a representative of CE and IT devices, and mobile terminal is used as a control hub with user friendly interface. First, overall architecture overview is introduced,

and then the whole procedure of REWACON and specific configuration protocols are described. Finally, we introduce the message structure of REWACON in more detail.

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

AA controller node can join networks started by target nodes bycontroller node can join networks started by target nodes by pairing with the target.pairing with the target.

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.
