Next, I'd like to introduce our proposed timestamp compensation method.
The proposed timestamp compensation method forms a wireless node tree according to the number of commonly received frame at two nodes.
Ones the node tree is formed, the timestamp at a child node is converted onto the timestamp at its parent node using linear regression.
The timestamp conversion process is performed from the root node to the leaf node(s).
Since the accuracy of linear regression improves as the number of timestamp samples increases, the node pair, here we call as "link", with more commonly received frame becomes a higher-level branch. |
