IEEE 802.16 standard has not specified any algorithm for implementation of schedulers which has led to number of developments in recent past. Soft computing techniques like fuzzy logic based schedulers have also been proposed however integration of these schedulers into existing simulators is still a competing task. Although lot of help is available on web regarding integration of different algorithms in simulators but implementation of soft computing based algorithms in available simulators is still an open issue. This paper is an attempt to guide researchers towards implementation of fuzzy logic based scheduler in Qualnet simulator. Class diagram with sample code snippets are proposed to aid and guide researchers. The paper also discusses implementation of various quality of service mechanism for IEEE 802.16 networks.
