Title
QoS-aware resource allocation algorithm for OFDMA-WLAN integrated system
Abstract
In this paper, a resource allocation algorithm is proposed for different quality of service (QoS) guarantee, fair transmission and high data rate in orthogonal frequency division multiple access (OFDMA) and wireless local area network (WLAN) integrated system. First, different QoS requirements are converted into different rate requests for simplifying the optimization problem. Second, the sub-channels are assigned to reach certain QoS satisfaction level (QSL) before water-filling based power allocation. The channel resource is not allocated according to highest data rate; users will be assigned channels that best suit the needs. The proposed algorithm is compared with three other algorithms and the simulation results show that it can provide different QoS guarantees for different users while maintaining the system data rate and fair transmission.
