Key Issues & Design Challenges in WiMAX

Abstract

To 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. In current time to satisfy the increasing 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.
