QoS Based Performance Analysis of Scheduling Algorithms for WiMAX


Author(s): Mrs. P.SUDHA, Dr. A.RENGARAJAN

WiMAX (Worldwide interoperability for Microwave Access), is one in every of the recent technologies within the wireless world. The most goal of WiMAX is to deliver wireless communications with Quality of Service (QoS) during a secured setting. Owing to this Quality of Service (QoS) has become important issue in present era to differentiate oneself from alternative competitor technology. WiMAX (IEEE 802.16) is one such normal specifies general QoS design with varied components of this design is left undefined. Most significant part of this design is scheduling algorithm and this part is not defined and left open for vendors to implement as per their wants. In contrast to wireless LANs, WiMAX networks incorporate many QoS mechanisms at the MAC level for secured services for knowledge, voice and video. Its quality feature makes it completely different from the opposite IEEE 802.16 protocols that was supported Static WiMAX and provided the Wireless communication at fastened locations. In this paper the performance analysis of Cross Layer Scheduling (CLS), and TCP-Aware Uplink Scheduling (TCP-AUS). Finally CLS algorithm provide better performance compare to TCP-AUS and also increasing throughput, reducing delay and ART with number of MS is increased.
