摘要
针对目前现有的发布订阅规范(DDS)主要描述终端节点信息处理行为的实际,提出使用标签集中式机制完成发布订阅信息网络交互工作。理论分析了标签集中式发布订阅机制的数学模型,对往返时延等参数进行了理论计算。并仿真此机制下无线窄带网络中发布订阅信息交互机制对网络性能及参与者数量对发布订阅系统性能的影响。通过理论计算和仿真分析证明此机制在较小规模网络中有良好的性能。
The Data Distribution Service for Real-time Systems（DDS） mainly described how data was deal with in single node,not mode of data-exchange between nodes.The centralized label publication/subscription mechanism was used for data-exchange in this article.In the wireless network,especially low speed wireless network,it is important to research on performance of this Mechanism and relationship among number of node,RTT（round-trip time） and receiving-to-sending ratio.From the simulation,we derive the conclusion that centralized label publication/subscription mechanism is suitable for the network of some nodes.
