A Cross Layer Design of Fair Resource Allocation Algorithm for Downlink OFDM System

摘要：

A basic problem in wireless network optimization is the inapplicability of the layered structure. This paper examines a cross layer resource allocation algorithm for downlink OFDM system. The tradeoff of fairness and efficiency is well balanced with cross layer interaction by considering the traffic parameter and fairness among users in link layer as well as the influence of channel state and power transmission limitation. The experimental results reveal the guarantee on steadiness and fairness for users improves a lot while using the cross layer method with a little loss on power efficiency compared with pure physical adaptive counterpart.
