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.

“…There are several techniques operating on the link layer, which attempt to ameliorate the impact of wireless errors [1,11,18,19]. The most remarkable implementations, which provide error correction, are Forward Error Correction (FEC) and Automatic Repeat Request (ARQ) [11].…”

“…In contrast to transport-layer solutions, a series of independent mechanisms have been proposed, which normally interact with the transport protocol and provide reliable transmission over wireless links [1,11,18,19]. Most of them operate on link layer and generally are considered more efficient than physical-layer techniques, such as spread-spectrum and OFDM modulation or channel coding.…”

End-to-end loss differentiation for video streaming with wireless link errors

Video delivery in heterogeneous wired/wireless networks is challenging, since link errors commonly degrade throughput performance, smoothness, and eventually impair the playback quality. We present an end-toend Loss Differentiation Mechanism (LDA) which effectively decouples congestion from wireless loss in order to abolish the damage of error-induced multiplicative decrease on flow throughput and smoothness. The proposed LDA relies on Round Trip Time measurements to estimate the queuing delay and determine the appropriate error-recovery strategy. This mechanism can be easily adapted and incorporated into existing Additive Increase Multiplicative Decrease (AIMD) protocols, enabling them to utilize the available resources more efficiently. In this context, we incorporate the LDA into AIMD-based Scalable Streaming Video Protocol (SSVP), an end-to-end TCP-friendly protocol optimized for video streaming applications. Based on simulation results, we show that the combined approach provides the desired functionality to bind operationally wired and wireless links, within the framework of bandwidth efficiency, smoothness, and fairness.

Transmission Control Protocol (TCP) is connection oriented transport protocol used on IP in wireless medium and it insists lossless data transmission in proper order. When TCP is used as a transmission protocol where physical layer is wireless medium, results high packet reordering due to bursty traffic and drastic variation in quality of service with respect to time. By sharing the same path for data and acknowledgement increases the traffic and collision, resulting in reduced throughput. In order to improve QoS this paper proposes a solution "Improved Delay the Duplicate Acknowledgement" (IDDA). This reduces traffic and spurious retransmissions, thereby improving TCP performance.
