Traffic modeling contributes remarkably to network design and performance evaluation in wireless networks. Various traffic models have been proposed for wireless networks thus far.. In order to provide a better understanding in this area, the article presents a detailed investigation to current studies of traffic models in different wireless networks. And then the origins of model differences are...
In this study, feasibilities of HTTP specific acceleration and TCP optimization in mobile network are analyzed through comparisons. Based on these analyses, practicable accelerator architectures for Web latency reduction are presented. Furthermore, we proposed that a boost in performance is feasible by either deploying cooperative proxies with concurrent connection or combining the characteristics...
In this paper, we described the correlations between uplink TCP packet latency, behavior of TCP and behavior of application. Pearson product moment correlation analysis and partial correlation analysis are worked out to characterize correlations between five user perceived parameters. Our study demonstrated that the packet latency in uplink direction mainly caused by TCP setup time instead of the...
In this paper, we described the correlations between user perceived Web response time and the asymmetrical link characteristics. Our study demonstrated that the HTTP compression strongly affects the Web response time when uplink resources are limited. The constraints on uplink degrade Web performance seriously. In addition, we also found that it is possible to reduce Web response time through cross...
In this paper, we described the correlations between uplink packet latency of TCP, application traffic characteristics and uplink characteristics. Our study demonstrated that the packet latency in uplink direction mainly caused by TCP setup time instead of the packet size and the bandwidth. In addition, we also found that TCP failure number varies with the configurations of PDCH in BSS.
In this work the authors show how the asymmetry characteristics of wireless network strongly affects the Web response time of user. It is found that uplink delay degrades Web performance because additional bytes overhead and time overhead are introduced. On the other hand, the study also shows that reduction of Web response time is possible through protocol optimization on different layer of protocol...
Applications over HTTP are expected to play its persistently important role in the future heterogeneous networks. The purpose of this study is to analyze emerging characteristics of HTTP traffic which has dramatically changed both in payload and transfer method in the past few years. Beginning with a discussion of well-known models in literature, we emphasize on their applicability in the future networks...
