Customer Satisfaction Based Resource Allocation for OFDM System with Multimedia Traffic

This paper presents Customer Satisfaction (CS) based resource allocation strategy in orthogonal frequency-division multiplexing (OFDM) wireless system with multimedia traffic. The risk aversion utility functions are analyzed, based on which, the CS utility and the CS resource allocation strategy are proposed. Compared with the Proportional Fairness (PF) utility, the CS utility enables the system to adjust its resource allocation according to both the traffic requirements and the resource situation. Numerical results demonstrate that the CS resource allocation strategy outperforms the PF strategy in both real-time (RT) traffic and best effort (BE) traffic.
