A framework for effective quality of service over wireless networks

This paper firstly highlights areas that have the potential to influence or directly affect the final outcome of Quality of Service (QoS) levels and the effectiveness of security in a wireless network environment. A Delphi methodology survey was then carried out by selecting a panel of experts with first-hand knowledge in this area. This research methodology process was conducted over three separate rounds of survey questionnaires for further refinement. The results gathered from the research indicated that the panel highly valued scenarios that supported further enhancements to existing QoS functions as well as continual development to newer and more cost effective functions that increase the level of control of QoS levels. Security was felt to be a secondary concern, a worrisome development given the increasing importance of it in modern networks (Siau and Shen, 2003; Olla and Patel, 2003; Tan, Wen and Gyires, 2003).
