In SHT model, dynamic nodes are clustered to stable nodes so as to control the dynamic change of DHT topology network. SHT模型利用了对等网络节点存在的会话异构性,将动态节点聚簇在稳定节点(SN),从而降低了网络动态节点对于DHT拓扑的强干扰性。
The mobility prediction method based on link expiration time is utilized to choose stable neighbors and to expand the replica to relatively stable nodes. DARAM-MP算法使用移动预测的方法动态确定副本节点的稳定邻居节点集,将副本扩展到相对稳定的邻居节点上,目的是减小由于移动节点间的边缘移动给副本放置带来的不稳定性。
In the stage of stable phase nodes in the same cluster communicate with each other by one-hop routing and cluster head communicates with sink node by multi-hop routing and finally fused data are sent to the control center through energetic lines. 稳定阶段中簇内节点通过单跳路由和簇首进行通信,由簇首处理好的数据通过多跳路由的方式发送给sink节点融合处理,继而通过有源线路发送给控制中心。
For backbone networks, by fully making use of characteristics of stable topology of nodes, this protocol adopts the optimal routing strategy for off-line configuration. When the link or node fails, maintaining mechanism adopts link-reverse algorithm to adjust the routes automatically for improving invulnerability. 对于骨干网,充分利用骨干网中节点拓扑稳定的特点,采用最优化策略对路由进行静态离线配置;当节点或链路发生故障时,采用链路反转算法对路由进行维护,提高抗毁性。
As to the background of coal mine positioning system, we study the issues about stable localization of mobile nodes. 针对煤矿井下定位系统这一应用背景,对移动节点的稳定定位问题进行了研究。
