Splet17. jun. 2024 · TPSN (Timing-sync Protocol for Sensor Networks) 基本思想: TPSN协议采用 层次型 网络结构,首先将所有节点按照层次结构进行分级, 然后每个节点与上一级的一个节点进行(两次报文交互的)时间同步 ,最终所有节点都与根节点时间同步。 节点对之间的时间同步是基于“发送者-接收者的”同步机制。 TPSN协议包括两个阶段: 第一个阶段 … SpletHow it works. Container numbers have the format XXXU1234567. We use the first 4 letters to automatically send the request to the correct company. If the company is not supported or you want to select a specific company you can do this manually after tracking. If you know of any companies offering tracking that is not included please contact us!

Moreover, TPSN is completely flexible and can be easily tuned to meet the desired levels of accuracy as well as algorithmic overhead. TPSN also comes with an auxiliary benefit of improving the accuracy of other basic services in sensor networks such as localization, target tracking, aggregation. 2.
