Abstract

A resource management scheme for multimedia ad hoc wireless LANs (AWLAN) based on orthogonal frequency division multiplexing-code division multiple access (OFDM-CDMA) is presented. This scheme combines distributed resource management and OFDM-CDMA techniques to support multimedia services with QoS guarantees. The performance evaluation results for broadband wireless access (BWA) type physical layer supporting MPEG traffic sources shows that when the number of nodes is about 50 and the mean session arrival rate is less than 0.1, we can get a blocking probability of 10^-2 and the QoS loss probability of 10^-1.
