“…It is first proposed in telecommunication networks. There are few papers which studied how to use the QoS information in the Information Retrieval System (IR system) [39][40][41][42][43][44]. They are mainly used in digital libraries or other distributed information systems such as distributed search engine systems.…”

Text, link and usage information are the most commonly used sources in the ranking algorithm of a web search engine. In this thesis, we argue that the quality of the web pages such as the performance of the page delivery (e.g. reliability and response time) should also play an important role in ranking, especially for users with a slow Internet connection or mobile users. Based on this principle, if two pages have the same level of relevancy to a query, the one with a higher delivery quality (e.g. faster response) should be ranked higher. We define several important attributes for the Quality of Service (QoS) and explain how we rank the web pages based on these algorithms. In addition, while combining those QoS attributes, we have tested and compared different aggregation algorithms. The experiment results show that our proposed algorithms can promote the pages with a higher delivery quality to higher positions in the result list, which is beneficial to users to improve their overall experiences of using the search engine and QoS based re-ranking algorithm always gets the best performance.

“…QoS has been an active research topic in several areas. Rocha eta/ [39] tried to analyze several performance factors of a wireless mobile network and found that the user mobility and the cell size can directly impact the QoS of the whole communication network. Hereby, adding these two factors in QoS control can greatly help to simulate and design a wireless network.…”

Without their care and support, this thesis would not have been finished.Firstly, I would like to express my deepest gratitude to my supervisor Dr. Cherie Ding for her guidance and constant support in helping me to conduct and complete this work. She discussed with me, kindly helped me solve problems I encountered when doing research work, and always gave me encouragement, which inspired me to keep stepping forward. To Cherie, I express my heartfelt thanks.I want to thank my co-supervtsor Dr. Dimitri Androutsos for his kind help and encouragement. He always shows his caring nature whenever we meet. He also invested time to review my thesis carefully and provide valuable comments. Without his support, the study could not be done.Many thanks to all the people I have come to know in computer engineering department, whose friendship and companionship I will always enjoy and get refreshed. I owe my sincere appreciation to my wife Chaoran Chen, who gave me space and consistently encouraged me while I was studying. These acknowledgements would not be complete without recognizing my parents. I could not do this without their unfailing love, affection and invaluable support in my life and studies. To each of them, my thanks and my love.

Traffic engineering is at the heart of telecommunications engineering. In telecommunication engineering, we have recently experienced a revolution in the form of mobile cellular network generations. History shows a close relationship between the advancements in both telecommunications networks and their corresponding engineering methods. This survey employed qualitative document analysis to chronologically explore the evolution of, and interrelationships between traffic engineering and the mobile cellular networks from 1990s todate. It is evidently a case of the causality dilemma on which of the two influences the other. Neverthelelss,we are currently at the right point in time to make giant leaps in both traffic engineering methods and network technology revolution. This study points out the opportunities that the current state of affairs avails to research in these fields.
