“…When a TCP connection is established over some wireless networks, it has to deal with other types of noncongestion packet loss, including the transmission loss over wireless links and disconnection loss due to host or network mobility. There have been some research in enhancing TCP for such noncongestion wireless loss [29], [34], [35], [36], [37], [38]. TCP-DCR [29] is so far the only work that deals with performance problems due to both packet reordering and reliable link-layer retransmissions.…”

Abstract-Transmission Control Protocol (TCP) is the most popular transport layer protocol for the Internet. Due to various reasons, such as multipath routing, route fluttering, and retransmissions, packets belonging to the same flow may arrive out of order at a destination. Such packet reordering violates the design principles of some traffic control mechanisms in TCP and, thus, poses performance problems. In this paper, we provide a comprehensive and in-depth survey on recent research on packet reordering in TCP. The causes and problems for packet reordering are discussed. Various representative algorithms are examined and compared by computer simulations. The ported program codes and simulation scripts are available for download. Some open questions are discussed to stimulate further research in this area.

“…Specifically, when a transmission error cause s apacket to be lost, TCP incorrectly activates its congestion control mechanism, resulting in poor performance. Much of the literature proposes end-to-end solutions that analyze the Round Trip Time of received packets [2,10] or use excplicit congestion notification to distinguish the cause of loss [3]. End-to-end solutions do not help to solve the unfairness problem in the MAC layer because they do not influence the backoff algorithm.…”

Abstract. We consider the impact of transmission errors on the backoff algorithm behavior in the IEEE 802.11 protocol. Specifically, since the backoff algorithm assumes that all packet losses are due to collisions, it unnecessarily backs off when a packet is lost due to a transmission error. Two performance problems arise as a result: (1) low throughput, due to unnecessary loss of transmission time; and (2) unfairness when two competing links have different transmission error rates. In this paper, we characterize this problem and propose three solutions to it. The solutions aim to provide discrimination between transmission errors and collisions such that the sender can back off appropriately. The first algorithm relies on receiver discrimination and feedback; the receiving radio can in many instances differentiate between collisions and transmission errors. The second algorithm estimates the clear channel quality, and backs off if the observed quality deviates from the clear channel quality (indicating collisions). The third algorithm develops the probability of collision as a function of the number of observed idle slots during contention, and uses this probability to control the backoff algorithm. We show via simulation that the techniques significantly improve both performance and fairness of IEEE 802.11 in the presence of transmission errors.

“…Casablanca [38], which applies a simple biased queue management scheme to discriminate congestion losses from random losses to improve the TCP performance over wireless networks. The key idea of TCP-Casablanca is to derandomize congestion losses so that the distribution of congestive losses differs from that of random wireless losses.…”

he Internet provides a convenient and cost-effective communication platform for electronic commerce, education, and entertainment. The success of the Internet stems from its capabilities to support survivable, robust, and reliable end-to-end data transfer services for a myriad of applications running over a set of end-systems. The Internet originated from the Advanced Research Projects Agency Network (ARPANET) designed to support survivable military communications. Currently, the Transmission Control Protocol (TCP) [1] is the most popular transport layer protocol for point-to-point, connection-oriented, in-order, reliable data transfer in the Internet. TCP is the de facto standard for Internet-based commercial communication networks.
