摘要

Orthogonal frequency division multiplexing (OFDM) is one of the most promising modulation techniques being widely adapted for next generation wireless systems. The process of resource allocation (RA) is achieved by performing allocation of power over multiple subcarriers and multiple users ensuring a raise in performance by improving spectral efficiency and throughput of the network. The quality of service (QoS), in a network is interlinked with resource utilization. The users of wireless communication system demand for a certain level of service satisfaction. This research paper introduces a novice resource allocation algorithm which integrates scheduling, queuing with RA to elevate QoS level. The proposed RA algorithm works on classified QoS traffic flows to upgrade the network performance. The simulation and performance evaluation indicates efficacy and improvised utility of presented RA algorithm. The improved rate of throughput is achieved while considering QoS constraints and maintaining fairness for a certain classes of wireless network users.
