QoS assured downlink proportional fair scheduler for mitigation of starvation for nrtPS and BE in Wi-Max networks

The performance of any network essentially depends on quality of service required and also on the scheduling scheme. In our paper we focus on analyzing essential QoS parameters like delay, jitters, throughput associated to four proportional fair scheduling as proposed by Lim & Kim [2] and Gupta et al [3]. We extend the idea of parameters such that the number of downlink connections of rtPS for starvation is drastically reduced for lower priority of service flows of nrtPS and BE to achieve the optimal QoS requirement without the excessive resource consumption.
