摘要
为解决节点信道跳传频率高、媒介访问迟缓现象明显等问题,提出基于层次布局法的多节点通信信道优化方法。利用矢量通信路由协议,搜索相关的层次布局参数,并对通信节点的分配重量谱特性进行计算,完成基于层次布局法的通信节点分配。在此基础上,通过调整物理层帧格式、确定信道传输时间精度的方式,达到对多节点通信数据的链路定点化处理,完成基于层次布局法多节点通信信道优化方法的搭建。在同一物理平台中设计对比实验结果表明,与传统方法相比应用优化方法后,节点信道跳传频率下降明显,媒介访问物理延长时间得到有效控制,迟缓现象发生几率明显降低。
In order to solve the problems of high hopping frequency and slow media access,a multi-node communication channel optimization method based on hierarchical layout method is proposed. Vector communication routing protocol is used to search the relevant hierarchical layout parameters,and the weight spectrum characteristics of communication nodes are calculated to complete the distribution of communication nodes based on hierarchical layout method. On this basis,by adjusting the physical layer frame format and determining the channel transmission time accuracy,the link-fixed processing of multinode communication data is achieved,and the multi-node communication channel optimization method based on hierarchical layout method is built. The experimental results on the same physical platform show that compared with the traditional methods, the hopping frequency of node channel decreases significantly,the physical extension time of media access is effectively controlled,and the probability of delay phenomenon is significantly reduced.
