  4. Abstract:
  5. In this paper we discuss and analyze an enhanced media access control (MAC) layer protocol which uses the signaling method benefits of physical layer in order to provide different quality of service (QoS) levels in optical code-division multiple-access (OCDMA) packet networks. In the proposed network architecture the users are categorized into the high and low classes of service. Users of each class transmit at the same power level and different from the other classes' users. Also, the MAC of each user estimates the amount of interference on the channel and adjusts the packet transmission's time to improve network performance. Through simulation it is shown that the combination of appropriate power assignment to users and proper MAC algorithm can provide various QoS metric levels on metrics such as normalized throughput and channel access delay. This is achieved by dividing the available resources of the OCDMA network between the users of each class. © 2008 IEEE
