The advent of portable laptop computers, palmtops, and personal digital assistants with integrated communication capabilities facilitates mobile computing. With an increasing amount of audio and video being sent over public, packet-switched networks, the ability to provide Quality of Service (QoS) guarantees may be more important in today's networks. Therefore, supporting a high Quality of Service (QoS) in delivering voice, video and data in this paper has emerged as one of the most important challenge of the new century. This paper covers the various QoS techniques for wireless networks.
