传统光纤光栅传感网络具有灵活性低、移动性差等缺点。提出采用无线通信方式进行数据传输,构建一个新型的光纤光栅无线传感网络。设计了该传感网络的MAC层协议-FG—MAC(FiberGrating Media Access Control)协议,并与IEEE802.11协议在时延、吞吐量和能耗三方面进行了比较分析,结果显示FG-MAC协议更适合该新型传感网络。
The conventional fiber grating sensor network is poor in flexibility, mobility,etc. A novel fiber grating sensor networks is introduced, which is based on wireless data transmission. The FG-MAC protocol (Fiber Grating Media Access Control) in MAC layer is designed, and is compared with IEEE 802. 11 protocol in time delay, throughput, energy consumption. The results indicates FG-MAC protocol is more suitable for the novel fiber grating sensor networks.
