Abstract

A QoS providing distributed resource management scheme for multimedia Ad Hoc Wireless LANs(AWLANs) based on orthogonal frequency division multiplexing-code division multiple access(OFDMCDMA) is presented. This scheme implements distributed resource management with granular OFDM-CDMA channel architecture to support multimedia services with QoS provisions. The performance evaluation result for broadband wireless access(BWA)-type physical layer supporting MPEG traffic sources shows that when the number of nodes is 50 and the mean session arrival rate is less than 0.1, we can get the blocking rate of 10-2 and the QoS loss probability of 10-1 when there is no control packet loss.
