Executive Summary

With recent advances in the development of wireless communication networks, Wireless Mesh Networks (WMNs) have been receiving considerable research interests in recent years. The need to support integrated services and ensure Quality of Service (QoS) satisfaction for various applications is one of the fundamental challenges for successful WMN deployment. In order to provide differentiated services, Medium Access Control (MAC) should have priority management at the link layer. In Code Division Multiple Access (CDMA) based WMNs, the interference phenomenon and simultaneous transmissions must be considered. This paper proposes two priority schemes for MAC in a distributed CDMA-based WMN, taking into account interference, multimedia services, QoS requirements, and simultaneous transmissions.
