Protection and Security Aware QoS Framework for 4G Multihop Wireless Networks

Abstract

The Worldwide interoperable for Microwave Access (WiMAX) and Long Term Evolution (LTE) standards have well-defined Quality of Service (QoS) and security architecture. However, the details of Radio Resource Management (RRM) components, such as Call Admission Control (CAC) and Packet Scheduling (PS), are still open research topics. Next, some security issues are not yet resolved in the WiMAX or LTE standards. Finally, the multihop networks fail to consider the performance degradation problem during relay nodes failure. Therefore, the main objectives of this research work are to: (1) develop a new RRM framework to address QoS, (2) provide stronger security without affecting QoS performance, and (3) maintain the QoS of the network in the case of relay nodes failure.In terms of QoS, the proposed CAC in the Base Station (BS) reserves the bandwidth adaptively based on most recent requests from high priority users. When the Though only my name appears on the cover of this dissertation, a great many people have contributed to its production. I owe my gratitude to everyone and because of them my graduate experience has been one that I will cherish forever. I would like to thank Carleton University and the Systems and ComputerEngineering department for giving me the opportunity and financial assistance to pursue the PhD program.My deepest gratitude is to my advisor, Prof. Chung-Horng Lung. I have been amazingly fortunate to have an advisor who gave me the freedom to explore, and at the same time the guidance to recover when my steps faltered. I am grateful to him for holding me to a high research standard and enforcing strict validations for each research result, and thus teaching me how to do the research. Actually, there are no words to describe about his knowledgeable guidance, extremely helpful comments to improve my writing and moral support during my tough time.
