The link quality of wireless mesh networks is variable, hence dynamic route modifications based on changes in link quality can improve communication performance. A drawback of the route modification is the occurrence of order errors, which triggers retransmission control in TCP communication. However, retransmission is unnecessary for order errors in route modification as retransmission is redundant. In this study, they propose a method that discriminates the causes of order errors on the basis of their TCP sequence numbers and reception intervals.
