Abstract—A broadband wireless network performs several operations namely, QoS, resource allocation and scheduling in Multi-hop wireless networks in which Scheduling plays a vital role while transmitting packets in Multi-hop wireless networks. An efficient scheduling mechanism can provide solution to certain problems like collision, delay, interference etc., They are implemented based on the different network topologies namely, Point-to-MultiPoint (PMP) and Mesh mode and they provide improvement over several parameters such as, high-data-rate, scalability and mobility etc., Recently used network topology is Mesh network, which supports Multi-hop communication while transferring data packets in a network. In this paper, we present a wide survey on scheduling mechanisms in broadband wireless networks. We discuss the current mobile WiMAX (Worldwide interoperability for Microwave Access) technology, different scheduling mechanisms and its issues.

Index Terms—multiple-input-multiple-output (MIMO), quality of service (QoS), adaptive modulation and coding (AMC), hold off time, next transmission time (Next_Xmt_Time), medium access control (MAC).
