Power Control to Enable QoS for Indoor Wireless Infrared CDMA Networks

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.
