一种实时传感器网络协议的设计与实现

Design and implementation of a real-time sensor network protocol

针对工业现场监控系统传感器网络的组成和特点,综合传统传感器网络协议的优点,提出了一种独立于开发者和使用者、在应用层又具备一定扩展性的轻量级实时传感器网络通信协议(RTSN),通过建立主/从通信和事件驱动的通信模型,有效提高了系统对实时事件的响应能力.文中详细介绍了系统结构、协议的物理层和数据链路层、传感器节点管理以及事件驱动的通信模型.最后,在3块Cyclone Ⅱ EP2C35F672C8开发板上实现了RTSN节点模型,从而验证了协议的有效性.

Integrated with the advantages of traditional sensor network protocols, a novel extensible lightweight sen sor network communication protocol in application layer-RTSN （Real Time Sensor Network）, which is independent with developer and user, is proposed, aimed at the structure and characteristics of sensor network in industrial field supervision. In order to improve the real time response performance, a master/slave and event-driven communication model is established in RTSN. The architecture of RTSN is introduced at first, and then the physical layer and data link layer of the communication protocol, the management of sensor nodes and the event driven communication model are presented in detail in Section Ⅱ. Finally, in Section Ⅲ, the RTSN node model has been implemented on three Cyclone Ⅱ EP2C35F672C8 development boards. And the real-time protocol is validated and analyzed on these boards.
