A Zigbee and Sip-Based Smart Home System Design and Implementation

Abstract

This investigation presents a Zigbee and Sip based smart home system(ZSS) that automates home-service operations and remote access. The ZSS home system comprises five subsystems,namely home automation network,home IP netework,home gateway,remote access unit, and cloud service unit. The home automation network is a wireless sensor network , responsible to sample sensors data and control actuators by Zigbee instructions. Security system adopts IP network technology to  transmit videos from IP cameras to remote units. A home gateway middleware is designed to extract atomic service provied by a single device, then customize service rules which can meet variable user demands.Peer to peer transparent data channels between remote mobile phones and home devices are set up by Sip framework to overcome connection issues due to network address translation and dymaic public IP address. A novel  data stream algorithm named GCOKDE is exploited to get probability density distribution of environmental parameters which can be uesd for the condition value of service rule.At the end,this study constructes a prototype to reveal the procedure of realization.
