In summary, most of the research is focused on packet scheduling, but it is not clear yet which scheduling algorithms will work best with 80216 most of the testing has been done in simulation, so one of the main challenges may be to get reliable performance evaluations to create a heuristic model. Computing and all those who asked “how is your thesis going” these memories at the school of computing will always be cherished i am grateful for the emotional, financial and nutritional support of my family. Ahmad, mohammad hamidullah (2011) qos scheduling in ieee80216/wimax networks masters thesis, concordia university. Packet scheduling has drawn a great deal of attention in the field of wireless networks as it plays an important role in distributing shared resources in a network the process involves allocating the bandwidth among users and determining their transmission order in this paper an uplink (ul) scheduling algorithm for the mobile worldwide interoperability for microwave access (wimax) network. Worldwide interoperability for microwave access (wimax) is based on the ieee 80216 standard the ieee 80216-2004 standard (ie fixed wimax) provides specification for the medium access control (mac) and physical (phy) layers for wimax a critical part of the mac layer specification is scheduling, which resolves contention for bandwidth and determines the transmission order of users.
