Book Description
For the multiple-access protocol in wireless network, it is a scheme to control the access to a shared communication medium among various users. Access protocol can be grouped due to the bandwidth allocation mechanism, which can be static or dynamic, and the type of control mechanism implements. Each Media Access Control (MAC) uses a different media or multiple accesses schemes to allocate the limited bandwidth. It is required to develop simple and efficient resource management protocols for these network results in reduced processing cost, faster processing and a better use of network resources. When a mount of traffic is classified by different flow characteristics and then QoS requirement increases the utilization of the network resources. The orchestrated multimedia transmission is expected that the various elements of the multimedia service will be synchronized at the receiver node. There is a need for dynamic resource allocation protocols to take care of the various types of input sources. Static optimal and a dynamic optimal resource management protocols have been developed and evaluated.

Book Description
Multimedia communications poses a number of challenges to the wireless networks. Traditional multiple access mechanisms in wireless local area networks (WLANs) are not suitable for conveying voice and video traffic. Various interferences, like intra-flow and inter-flow interference, detrimentally affects video streaming quality. Recently standardized multiple-input multiple-output (MIMO) technology in WLAN, IEEE 802.11n, although increases the data rate, its rate adaptation schemes cannot effectively support video streaming rates. On the other hand, the lossy nature of wireless networks results in inaccuracies in quality evaluation of video streaming. Such inaccuracies create hurdles for future development of multimedia communications in wireless networks. We propose to consider the characteristics of the multimedia application and that of wireless communications together, and take the advantages of these properties to develop communication protocols which can support multimedia delivery effectively. We propose a new multiple access protocol, Time Division Carrier-Sensing Multiple Access (TD-CSMA). Using the predictability of real-time traffic, TD-CSMA doubles the capacity of co-located multiple WLANs compared with the legacy CSMA. We also propose a new rate adaptation scheme, Video-aware Rate Adaptation (VARA). Based on the streaming rate variation of videos, VARA achieves the perfect quality for the high-definition (HD) video streaming in MIMO WLANs. Finally, by taking the impact of packet loss in wireless networks on video quality into account, we propose new video quality metrics. The new metrics can accurately evaluate the spatial and temporal quality of video streaming in wireless networks. From extensive experiments and subjective tests, our metrics show an correlation greater than 0.9 with the Mean Opinion Score (MOS) of human subjects. With the proposals in this thesis, we can greatly improve the performance of multimedia communications over wireless networks.

Book Description
This book is a comprehensive guide to understanding the design of wireless multimedia communications systems. Covering mobile video, voice, and data communications, it provides both professionals and students with an introduction to the problems and solutions of communicating multimedia traffic at high data rates over a radio channel for short distances. Wireless Multimedia Communications begins with an examination of the physical layer of the Open Systems Interface (OSI) stack, modeling the radio channel impairments, including path loss and multipath distortion. The book addresses infrared and satellite wireless channels and the digital modulation approaches used to convey information over these channels. It compares possible approaches to transmitting multimedia traffic, including equalization, multicarrier modulation, and spread spectrum. The book also presents an in-depth discussion of error control, with a look at the emerging and promising field of turbo coding. At the data link layer, the book presents an evaluation of Medium Access Control (MAC) protocols-such as Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Code Division Multiple Access (
