	Research of new wireless sensor network protocol: ZigBee RF4CE (EI CONFERENCE) 会议论文 OAI收割 International Conference on Electrical and Control Engineering, ICECE 2010, June 26, 2010 - June 28, 2010, Wuhan, China 作者: Xu Z.-J.; Li D. 收藏 \| 浏览/下载：17/0 \| 提交时间：2013/03/25 Currently most existing remote controls for consumer electronics use infrared remotes (IR) technology to control devices which Increases the demand for advanced functionality that cannot be supported by existing IR. RF remotes provide new levels of interactivity and convenience for today's digital home when compared to IR remotes. New network protocols: ZigBee RF4CE are helping to make this technology accessible to us. In this paper we first introduce the architecture and primitives of the ZigBee RF4CE node initialization service then present the researches of the Application layer and Network layer respectively. Focusing on the functions of Network layer including: frequency usage service transmission control service discovery service power saving service pairing service and security service. 2010 IEEE.
