Channel based resource allocation mechanism (CBRAM) in WiMAX

Abstract

WiMAX provides a wide range of growing requirements of services and mobility of user that has made allocation of resources a focusing area for the researcher. The goal of the WiMAX Network, based on IEEE 802.16e standard, is to provide the best available quality of service. Several parameters are considered to ensure QoS and efficient resource allocation in multi classes. Considering deficiency of standard policy for scheduling and resource allocation in IEEE standard. This paper focuses on key issues and the design factors of existing techniques. A new mechanism is proposed for allocation of resources, Channel Based Resource Allocation Mechanism (CBRAM). To achieve this objective an analytical technique is used to derive bounds on system capacity in channel distribution. The research gap is to analyze the performance of the existing resource allocation mechanisms based on channel condition or SNR ratio. To fill the gap an optimal hybrid resource allocation technique is proposed to ensure resource allocation efficiently.
