传统的光纤光栅传感网络具有灵活性低、移动性差等缺点。文章作者构建了一种新型的光纤光栅无线传感网络,该网络融合了无线通信和光纤光栅传感的优点。同时还设计了节点结构,并根据实际应用场景提出了该传感网络的路由协议——RT(路由选择表)协议。在NS2(Network Simulator)中,从分组投递率、时延和能耗等3方面与Flooding协议进行了比较分析,结果显示RT协议更适合该新型传感网络。
As the conventional fiber grating sensor network is poor in flexibility and mobility, we propose a novel fiber grating wireless sensor network, which integrates the merits of wireless communications and fiber grating sensors and design the node structure and the routing protocol Routing Table (RT) for this network in line with the actual application sceneries . In NS2 (Network Simulator), we compare it with Flooding protocol in delivery ratio, delay and power consumption, the results of which show that the RT protocol suits the new sensor network better.
