  4. Abstract:
  5. Wireless infrared optical CDMA (W-OCDMA) is a new developing technique with some useful applications. Control and efficient use of optical power is a key issue in analysis and design of these systems. Also, multi user interference is a major source if impairment in these system. As a result, power control is a key issue in design and implementation of these systems. In this article we investigate a Dynamic Resource Management Algorithm (DRMA) as a framework, which employs power control to enable QoS in terms of reliability for multimedia traffic in W-OCDMA networks using Optical Orthogonal Codes (OOC's). A numerical method is also proposed to overcome computational difficulties of call admission control in base station to control user's power variation for different service levels. The results demonstrate techniques that can be used to create a local area W-OCDMA network with differentiated service. © 2006 IEEE
