HTTPEP: a HTTP Performance Enhancing Proxy for Satellite Systems

Broadband satellites enable Internet access for remote communities and niche markets such as ships and airplanes. However, their inherent characteristics, such as long delays and limited resources, significantly degrade the enduser’s web browsing quality-of-experience. In this paper, we propose a novel HTTP Performance Enhancing Proxy (PEP) that accelerates web-browsing and improves the utiliza...

Enhancing Hyperlink Structure for Improving Web Performance

The Impact of Computer–Assisted Language Learning (CALL) /Web-Based Instruction on Improving EFL Learners’ Pronunciation Ability

The purpose of this study was to investigate the effect of CALL/Web-based instruction on improving EFL learners’ pronunciation ability. To this end, 85 students who were enrolled in a language institute in Rasht were selected as subjects. These students were given the Oxford Placement Test in order to validate their proficiency levels. They were then divided into two groups of 30 and were...

Evaluation of performance enhancing proxies in internet over satellite

Performance enhancing proxies (PEPs) are widely used to improve the performance of TCP over high delaybandwidth product links and links with high error probability. In this paper we analyze the performance of using TCP connection splitting in combination with web caching via traces obtained from a commercial satellite system. We examine the resulting performance gain under different scenarios, ...

Enhancing Web Search Performance with Active User Categorization

Active user categorization system with interest based user clustering is proposed to extract the suitable group of pages for enhancing the web search performance. Existing users are grouped in light of the Swarm Intelligence (SI) methodology of Particle Swarm Optimization (PSO). The keyword based methodology is proposed to consider the user interest comparability for separating the group of exi...

Performance of Different Proxy Concepts in UMTS Networks

It is well known that the large round trip time and the highly variable delay in a cellular network may degrade the performance of TCP. Many concepts have been proposed to improve this situation, including performance enhancing proxies (PEPs). One important class of PEPs are split connection proxies, which terminate a connection from a server in the Internet in a host close to the Radio Access ...
