“…In such a split-connection approach, a specialized transport protocol like ATP [16] may run in the wireless part whereas the wired part uses standard TCP, e.g., TCP NewReno. However, a straightforward split-connection approach does not preserve the end-to-end semantics of TCP and requires complicated handover procedures in case of mobility [4].…”

This paper introduces an effective congestion control pacing scheme for TCP over multihop wireless networks with Internet connectivity. The pacing scheme is implemented at the wireless TCP sender as well as at the Internet gateway, and reacts according to the direction of TCP flows running across the wireless network and the Internet. Moreover, we analyze the causes for the unfairness of oncoming TCP flows and propose a scheme to throttle aggressive wired-to-wireless TCP flows at the Internet gateway to achieve nearly optimal fairness. The proposed scheme, which we denote as TCP with Gateway Adaptive Pacing (TCP-GAP), does not impose any control traffic overhead for achieving fairness among active TCP flows and can be incrementally deployed since it does not require any modifications of TCP in the wired part of the network. In an extensive set of experiments using ns-2 we show that TCP-GAP is highly responsive to varying traffic conditions, provides nearly optimal fairness in all scenarios and achieves up to 42% more goodput for FTP-like traffic as well as up to 70% more goodput for HTTP-like traffic than TCP NewReno. We also investigate the sensitivity of the considered TCP variants to different bandwidths of the wired and wireless links with respect to both aggregate goodput and fairness.

“…In their scheme, backpressure towards the source node is established implicitly by passively observing the medium. Sundaresam et al [19] introduced ATP, and Anastasi et al proposed TPA [1], which are both new transport protocols for multihop wireless networks. ATP employs pure rate-based transmission of packets, where the transmission rate is determined using feedback from intermediate nodes along the path.…”

“…TPA uses a similar congestion control algorithm as TCP, in such that packets are transmitted window-based. Opposed to [1], [17] and [19] we consider mesh networks with Internet connectivity rather than pure multihop wireless networks.…”

Abstract.We introduce an adaptive pacing scheme to overcome the drawbacks of TCP in wireless mesh networks with Internet connectivity. The pacing scheme is implemented at the wireless TCP sender as well as at the mesh gateway, and reacts according to the direction of TCP flows running across the wireless network and the Internet. TCP packets are transmitted rate-based within the TCP congestion window according to the current out-of-interference delay and the coefficient of variation of recently measured round-trip times. Opposed to the majority of previous work which builds on simulations, we implement a Linux prototype of our approach and evaluate its feasibility in a real 20-node mesh testbed. In an experimental performance study, we compare the goodput and fairness of our approach against the widely deployed TCP NewReno. Experiments show that our approach, which we denote as Mesh Adaptive Pacing (MAP), can achieve up to 150% more goodput than TCP NewReno and significantly improves fairness between competing flows. MAP is incrementally deployable since it is TCPcompatible, does not require cross-layer information from intermediate nodes along the path, and requires no modifications in the wired domain.

Abstract. This paper proposes a novel reliable multicast transport protocol for multi-hop, wireless ad hoc networks (or MANETs) . To recover from the different types of Iosses that may occur in MANETs, our Reliable Adaptive Congestion-controlled Transport protocol, or Re-ACT, combines source-based congestion-and error control with receiverinitiated localized recovery. While the latter attempts to recover localized Iosses ( e.g., caused by transmission errors), the former is invoked only for Iosses and congestion that could not be recovered locally ( e.g., caused by global congestion) . Loss differentiation is an important component of ReACT and uses medium access control (MAC) layer information to distinguish between different types of losses. Through extensive simulations, we evaJuate ReACT's performance under a variety of MANET scenarios, including different affered Ioad and mobility conditions, and compare it agairrst a strictly end-to-end (i.e., no localized recovery) scheme. Our results show that ReACT is the best performer in terms of reliability. Our results also showcase the effect of ReACT's local recovery mechanism which quickly corrects error-and path breakage induced Iosses and thus manages to prevent the source from reducing its rate unnecessarily , t hus achieving significant throughput improvement with lower overhead when compared to the strictly end-to-end protocol.
