The IEEE 802.16 standard, which is called Worldwide Interoperability for Microwave Access (WiMAX) is a low cost solution for Internet access in metropolitan and rural areas; it provides both high throughput and large coverage broadband wireless access. Although it defines five service level classes to support real-time and bandwidth demanding applications, each class is associated with a set of Quality of Service (QoS) parameters. However, the standard does not specify which scheduling algorithm should be used to serve packets. Due to the wireless channel variability, scheduling mechanisms widely studied for wired networks are not suitable for IEEE 802.16 networks. In this paper, we introduce Deadline maximum Signal to Interference Ratio scheduler , which makes bandwidth allocation decisions based on information about the channel quality and deadline. Simulation results show the proposed approach gains more delivering packet and decreases the average end to end delay and improve the fairness index.

“…In [7][8][9][10][11][12][13][14][15], channel quality has not been taken into account and many of them are suffering from starvation due to strict priority consideration. Channel aware schemes can be classified into four classes such as fairness, QoS guarantee, power consumption and high system throughput.…”

IEEE 802.16 supports different scheduling services to grant Quality of Service (QoS) for multimedia applications. IEEE standard has not specified any scheduling algorithm for fulfilling QoS for different traffic classes. In this paper, we have modified the maximum Signal-to-Interference Ratio (mSIR) scheduling algorithm, where Bandwidth allocation to Subscriber Sta- tions (SSs) is not only depending on Signal-to-Interference Ratio (SIR) value of SS. Queue length of SS is also considered for providing service by the Base Station (BS). The simulation resultsshow that by using the proposed scheduler the throughput increased to 8.08% in comparison to the mSIR scheduler. The proposed approach optimizes the usage of the bandwidth and resources in the WiMAX networks by enhancing the overall throughput and decreasing mean sojourn time of real time Polling Services (rtPS) class. Moreover, it does fair management for SS having low SIR and high real time data to deliver.

WiMAX(worldwide interoperability for Microwave Access) networks are the networks which are responsible for providing many services like video, data and voice. The WiMAX technology satisfies the modern need of broadband internet through wireless access. For managing all these services through WiMAX, IEEE802.16 gives QOS (Quality of Service) parameter. In WiMAX, a fundamental challenge is to achieve high QOS so that various parameters like waiting time, end to end delay can be minimized and other parameter like execution time and network utilization etc. To obtain high QOS there is scheduling algorithm which is implemented at the base station and subscriber stations. In this paper we discuss scheduling algorithms and also compare the parameters (waiting time, turnaround time, execution time, packet drop age and packet delivery). We purpose a scheduling algorithm which is combination of greedy latency, distance calculation of user from base station, calculate the burst time and apply SJF on that burst values.
