WiMAX Scheduling Algorithm Key Issue and Design Challenges: Survey

Abstract

In recent time to satisfy the growing demand of broadband wireless access by using scare Resource of bandwidth is a biggest challenge for Researchers, in this time WiMAX (Worldwide Interopretability for Microwave Access) emerged as a better solution to fulfill that demand. WiMAX provides faster internet connectivity in Urban Areas as well as remote areas also where to deploy the DSL (Digital Subscriber Line) or other wired technology is difficult task. WiMAX structure is based on IEEE 802.16 OSI standard and defines the PMP (Point to Multipoint) and Mesh modes for transmission of information. To provide authentic services for voice, data and videos WiMAX define the various QoS parameters at Media Access Control (MAC) layer. In order to meet the QoS requirement Novel scheduling approach are required. In these papers efforts are made to examine and compare the various scheduling algorithm and its design challenges to implement the effective scheduling algorithm. It also discusses the various QoS parameters associated with scheduling approaches.
