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...
3G mobile communication networks such as UMTS provide wide area Web access. However, Web latency is usually beyond users' tolerable waiting time even in wired networks. In UMTS networks, mainly due to large RTTs and limitations of existing HTTP, Web latency increases dramatically. In this paper, we introduce a Web acceleration scheme, proxy-based object packaging and compression (POPC), for reducing...
Our study demonstrated that caching scheme performs better in high density mobile networks than in sporadic circumstance. Based on the analysis of correlation between cache performance and the zipf-like user behaviors, we proposed some possible methods to improve cache performance in high density mobile networks.
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 proposed an object packaging based cache scheme for GPRS network. Our study demonstrated that better performance can be achieved when packaging utilized. In addition, the scheme can be used for other resource limited networks.
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 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...
