“…This violates the end-to-end semantics of TCP and is incompatible with IP security which encrypts TCP headers [11]. Another approach is to freeze TCP state whenever persistent errors occur [8], [12]. While error conditions persist, TCP does not invoke its congestion control mechanisms.…”

“…While error conditions persist, TCP does not invoke its congestion control mechanisms. Wireless and congestion losses may be differentiated either via explicit loss notifications [8] or explicit congestion notifications [12]. Thus performance is not unnecessarily degraded, but recovery remains end-to-end and protocol software must be modified at various locations so as to generate these notifications.…”

Abstract-The performance of Internet applications over wireless links is disappointing due to the adverse effects of wireless errors on higher layer protocols and applications. This paper focuses on link layer enhancement mechanisms which attempt to hide these wireless impairments. We simulate file transfer and WWW browsing over TCP and continuous media distribution over UDP, in conjunction with various link layer schemes. Our results reveal that WWW browsing behaves differently than bulk file transfer, that some TCP aware enhancements have limited applicability and that UDP applications are best served by schemes inappropriate for TCP. We then describe a multi-service link layer architecture that simultaneously enhances the performance of diverse applications by supporting multiple error recovery schemes in parallel. In order to evaluate our architecture, we repeat our previous simulations with all applications executing simultaneously. The results reveal that with our approach each application achieves similar improvements as when it operates alone over its preferred link layer.

“…We use a well-known result on the throughput fluctuation in TCP transmission over MANET [11], [12]. In more details, TCP over MANET may become unstable due to frequent retransmission caused by MAC level collisions, route discovery in the network layer, or network partitions by node mobility.…”

Abstract-In order to analyze important properties of network protocols, such as robustness and applicability, we may need exhaustive tests to observe effects of various factors under different settings. For recent protocols on dynamic, large-scale and environment-aware networks such as wireless sensor networks and mobile ad-hoc networks, we should consider many factors due to diversity of hardware profiles, upper/lower layer protocols and physical environments. In this paper, we propose a comprehensive test method to analyze the effect of (usually 10 or more) factors on such network systems. Our method takes a set of factors to be considered and their (representative) domain values as inputs, analyzes their effects on the systems, and determines dominant factors that have impact on the performance and their interactions. Instead of applying exhaustive tests that require all the combinations of domain values, we take a step-wise approach that examines step-by-step suspected sets of factors, which requires fewer combinations. We also justify this approach based on a reasonable fault model. The approach also contains an analytical method to identify the performance characteristics. Through realistic case studies, we show that we could find sets of dominant factors in wireless networks systematically.

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.
