“…6. The only change from the previous case is that all schemes achieve lower throughput, due to the multiplicative loss effects of the two wireless links [22]. The exception is Berkeley Snoop which is even closer to Raw Link, as it is unable to retransmit both client requests in one direction and server replies in the other.…”

“…Berkeley Snoop only works in the direction from the wired Internet towards a wireless host due to its reliance on TCP ACKs. In the reverse direction, TCP ACKs are returned late and may even signify congestion losses [22]. Since only the base station makes retransmissions towards the wireless host, TCP data cannot be retransmitted over both wireless links in the path, thus we resort to TCP recovery for one of them.…”

“…Unfortunately, higher layers make assumptions about link performance that cannot always be met by wireless links. Thus, although supporting IP over these links is straightforward, their performance can be disappointing [22]. As the Internet evolves towards Quality of Service (QoS) provision so as to support applications requiring service guarantees, improving the performance of Internet applications over wireless links becomes critical.…”

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 made this assumption because we have no control over the amount of additional traffic going through the wireless network, and we would expect authentication traffic to be a negligible fraction of the overall traffic. We derived the throughput for the wireless network by degrading transmission speeds to account for frame errors using the measurements and analysis performed by Xylomenos and Polyzos [1999]. Figure 11 demonstrates that the response times start to climb rapidly at the point at which the KDC saturates and server delay exceeds wireless network delay.…”

Performance, in terms of user response time and the consumption of processing and communications resources, is an important factor to be considered when designing authentication protocols. The mix of public key and secret key encryption algorithms typically included in these protocols makes it difficult to model performance using conventional analytical methods. In this article, we develop a validated modeling methodology to be used for analyzing authentication protocol features, and we use two examples to illustrate the methodology. In the first example, we analyze the environmental parameters that favor one proposed public-key-enabled Kerberos variant over another in the context of a large, multiple-realm network. In the second example, we propose a Kerberos variant for a mobile computing environment and analyze the performance benefits realized by introducing a proxy to offload processing and communications workload.

Improving the end-to-end performance of TCP over wireless networks has been an active research area. When TCP operates in wireless networks, the performance of TCP degrades significantly. It is well known that frequent retransmission timeouts are the leading source of TCP performance degradation over wireless networks. Retransmission timeouts are unavoidable, when the fast retransmission of a lost packet fails to reach the destination. There have been many schemes developed for reducing the retransmission timeouts of TCP. However, these schemes have no mechanism to detect the loss of fast retransmitted packets over wireless networks. In this paper, we introduce an efficient TCP mechanism, called T-DLRP, which is able to detect the loss of fast retransmitted packets and react accordingly. To justify our contributions, we compared T-DLRP against TCP New Reno, Vegas, New Jersey, Veno, Cerl, and DAC via extensive simulations using Qualnet 4.5 simulator. The results demonstrate that our mechanism achieves significant improvement over existing TCP variants especially in a coexisted network with packet loss and fast retransmission losses. Compared to DAC, T-DLRP gains more than 70% improvement in terms of accuracy over wireless networks. Also, our experiments of multiple connections of the same TCP flows reveal that T-DLRP has better fairness compared to TCP NewReno.
