WiMax is a technology that provides wireless services at very high speed. The IEEE 802.16 standard provides the specification for WiMAX technology. The IEEE 802.16 provides QOS support, but it does not specify the details of how the QOS can be achieved for different types of applications. Bandwidth scheduling is one method by which the QOS requirements can be met. The amount of bandwidth allocated to different application depends on the type of scheduling algorithm implemented at the Base station and Subscriber station. Different vendors implement this scheduling architecture in their own way. The scheduling algorithm should be efficient. Lot of parameters like number of subscribers, upper bound on delay, jitter and bandwidth etc should be considered. This paper presents a survey of simple uplink scheduling algorithms for WiMAX. We have also carried out a simulation study of BE scheduling service on the uplink. The simulation is carried out using the NS2 simulator with the NIST implementation ver2.6 of Wimax module.
