“…Go Back N however is at best a marginal improvement over Raw Link. These results suggest that conflicting TCP and link layer retransmissions [7] are less of a problem than resorting to end-to-end TCP retransmissions.…”

“…For example, retransmissions delay real-time traffic, so they should be bypassed for non-TCP traffic [14], [20]. Another problem is that RLP recovery may interfere with TCP recovery [7], leading to conflicting retransmissions between the link and transport layers, at least if the link layer delay is comparable to the end-to-end delay.…”

“…To prevent conflicts with TCP retransmissions in this case [7], in Karn's RLP the sender abandons frames not received after some (by default 3) retransmissions [10]. Thus, delay over the link is bounded and the sender never stalls, given a sufficient window.…”

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.

“…Avoiding the violation of transport layer semantics comes at the cost of violating protocol layering, however. The advantages of TCP and link layer coupling is reduced link layer overhead and avoidance of conflicts between local and TCP retransmissions [7], but the scheme may require modifications whenever TCP is modified, and does not work for any other protocols.…”

We discuss the problems that arise when standard Internet protocols are used over wireless links, such as degraded Transmission Control Protocol (TCP) performance when wireless errors are interpreted as congestion losses. We use case studies drawn from commercial Wireless Local Area Networks and cellular telephony systems to illustrate these problems. Then, we survey some proposed approaches to mitigating such problems and examine their applicability. Finally, we look at the future of wireless systems and the new challenges that they will create for Internet protocols and state some goals for further protocol enhancement and evolution.

Carbon dioxide is a versatile, environmentally benign solvent for the synthesis of many polymeric materials. This review focuses on recent advances in the utilization of liquid and supercritical CO 2 as a reaction medium for polymer synthesis. Polymerization techniques with both chain‐growth and step‐growth mechanisms are discussed, including free‐radical, metal‐catalyzed, ionic, and bulk polycondensation processes.
