Executive Summary

Packet Reordering is a phenomenon on the Internet and must be taken into account when considering performance analysis in wireless networks. Due to various characteristics specific to wireless networks, such as signal fading and mobility, packets may be lost due to congestive and non-congestive losses. The non-congestive losses violate the design principles of some traffic control mechanisms in TCP and causes performance problems. In this paper, the authors study to evaluate the performance of four solutions for TCP packet reordering, namely, TCP-PR, TCP-DCR, TCP-DOOR, and RR-TCP, under wireless networks.
