Worldwide Interoperability for Microwave Access (WiMAX) networks were expected
to be the main Broadband Wireless Access (BWA) technology that provided several services
such as data, voice, and video services including different classes of Quality of Services (QoS),
which in turn were defined by IEEE 802.16 standard. The main objective of the broadband wireless
technologies is to ensure the end to end Quality of Service (QoS) for service classes. Wimax is a
revolution in wireless networks which could support real time multimedia services. In order to
provide QoS support and efficient usage of system resources an intelligent scheduling algorithm
is needed. The design of detailed scheduling algorithm is a major focus for researchers and
service providers. In this paper, we presented a review study to measure the performance of several
scheduling algorithms and proposed scheduling algorithms in Wimax.
