Tutorial Descriptions

Security of Multimedia Content in Digital Distribution Networks
Ahmet Eskicioglu, Brooklyn College, City University of New York

In recent years, advances in digital technologies have created significant changes in the way we reproduce, distribute and market intellectual property (IP). Digital media can now be exploited by the IP owners to develop new and innovative business models for their products and services. The lowered cost of reproduction, storage and distribution, however, also invites much motivation for large-scale commercial infringement. In a world where piracy is a growing potential threat, the rights of the IP owners can be protected using three complementary weapons: Technology, legislation, and business models. Because of the diversity of IP (ranging from ebooks to songs and movies), no single solution is applicable to the protection of multimedia products in distribution networks.
IP is created as a result of intellectual activities in the industrial, scientific, literary and artistic fields. It is divided into two general categories: (1) Industrial property - includes inventions (patents), trademarks, industrial designs, and geographic indications of source, and (2) Copyright - includes literary and artistic works such as novels, poems and plays, films, musical works, artistic works such as drawings, paintings, photographs and sculptures, and architectural designs.
A digital home network is a cluster of digital audio/visual (A/V) devices including set-top boxes, TVs, VCRs, DVD players, and general-purpose computing devices such as personal computers. Copyrighted digital multimedia content may be delivered to the consumers from a number of sources including the Internet, and satellite, terrestrial or cable television systems. It may also be made available as prepackaged media (e.g., a digital tape or a digital video disc) at retail stores. Before releasing their content for distribution, the content owners may require protection by specifying certain access conditions and digital rights. Although legal institutions exist for protecting intellectual property, complimentary technical measures are needed to sustain financial returns and to ensure incentives for new creations. Recently, two fundamental groups of technologies, encryption and watermarking, have been identified for protecting copyrighted multimedia content in digital distribution networks. Encryption-based technologies transform content into unintelligible form. This transformation, being reversible in nature, allows perfect recovery of content before consumption. Technologies based on watermarking embed data directly into content, resulting in imperceptible degradation in visual quality.
End-to-end security is the most critical requirement for the creation of new digital markets where copyrighted multimedia content is a key product. Three major industries have a vital interest in this problem: The motion picture industry, the consumer electronics (CE) industry, and the information technology (IT) industry. This tutorial is an overview of the work done for protecting the content ownersí investment in intellectual property. After an introduction to copyright and copyright industries, we examine how the technological, legal, and business solutions help maintain the incentive to supply the lifeblood of the markets.

Routing Protocols in Delay Tolerant Mobile Ad Hoc Networks: Overview and Challenges
Dr. Zhensheng Zhang, San Diego Research Center

In mobile ad hoc networks, nodes are constantly in motion and/or operate on limited power. When nodes are in motion, links can be obstructed by intervening objects. When nodes must conserve power, links are shut down. These result in intermittent connectivity. When no path exists between source and destination, network partition occurs. Examples of an intermittently connected network (ICN) are: a). An inter-planet satellite communication network where satellites and ground nodes may only communicate with each other several times a day, b). A sensor network where sensors are not powerful enough to send data to a collecting server or are scheduled to be wake/sleep periodically, c). A military ad hoc network where nodes (e.g. tanks, airplanes, soldiers) may move randomly and are subject to being destroyed. Applications in ICNs must tolerate delays beyond conventional IP forwarding delays and these networks are referred to as delay/disruption tolerant networks (DTN). New protocols specifically for DTNs must be developed as existing protocols designed for the Internet do not work properly. There are several different types of DTNs due to their different characteristics.
Recently there has been much research activity in the emerging area of intermittently connected ad hoc networks and delay/disruption tolerant networks (DTN). There are different types of DTNs depending on the nature of the network environment. Routing in DTNs is one of the key components in the DTN architecture. Therefore, researchers have proposed different routing protocols for different types of DTNs in the last few years. In this tutorial, we capture the state of the art in routing protocols in DTN networks. We categorize these routing protocols based on information used. For deterministic time evolving networks, three main approaches are discussed: the tree approach, the space and time approach, and the modified shortest path approach. For stochastic time evolving networks, the following approaches are reviewed: the epidemic or random forwarding approach, predication or history based approach (including per contact routing based on one hop information only and per contact routing based on average end to end information), the model based routing approach as well as approaches which control the movement of certain special nodes are reviewed. Recent development in erasure coding and network coding applied to DTNs are also discussed. The tutorial also identifies open research issues and intends to motivate new research and development in this area.

Dr. Zhensheng Zhang received his Ph.D. in electrical engineering from the University of California, Los Angeles in 1989. Dr. Zhang has over fifteen years experience in design and analysis of network architecture, protocols and control algorithms, with very strong backgrounds in performance analysis, modeling and simulation of the communication networks.

Using Conjoint Analysis to Determine System Requirements
Matthew Zieniewicz, US Army CERDEC

Conjoint Analysis is a powerful quantitative marketing modeling technique based on statistical methods that allows one to quickly and accurately determine the customer's priorities for a new product's features. It has risen in popularity over the past decade. One of the pioneering institutions in this technique is the Wharton School of Business at the University of Pennsylvania. With the emergence of new quantitative methods in marketing research, there is a new discipline emerging within marketing, sometimes referred to as marketing engineering.

This tutorial will give a quick overview of conjoint analysis and how it is applied to determine customer wants and needs. An introduction to the statistics behind the technique will be explained, with the emphasis on practical applications rather a formal proof. This technique can be used to determine system requirements, where the product proposed is unique and historical data on customer wants and needs is NOT available. A real-world example applied to a computer/communications system will illustrate how to use the technique. Upon completion of the tutorial, a working knowledge of conjoint analysis will be gained, with the ability to apply the technique on upcoming projects.

Broadband Wireless Access - The Next Wireless Revolution
Benny Bing, Georgia Tech Broadband Institute

Broadband wireless access is the third wireless revolution, after cellphones (1990s) and Wi-Fi (2000s). It is viewed by many carriers and cable operators as a ìdisruptiveî technology and rightly so. The broadcast nature of wireless transmission offers ubiquity and immediate access for both fixed and mobile users, clearly a vital element of next-generation quadruple play (i.e., voice, video, data, and mobility) services. Unlike wired access (copper, coax, fiber), a large portion of the deployment costs is incurred only when a subscriber signs up for service. An increasing number of municipal governments around the world are financing the deployment of multihop wireless networks with the overall aim of providing ubiquitous Internet access and enhanced public services. This tutorial will provide a comparative assessment of the key issues and technologies underpinning promising broadband wireless access solutions such as 802.16 (Wi-Max), long-range/multihop 802.11 (Wi-Fi), wireless DOCSIS, 3G/4G, mobile TV, digital TV broadcast, 802.20 (mobile broadband), 802.21 (media independent handoff and interoperability), and the emerging 802.22 (wireless regional area networks) standard. Key topics include licensed and unlicensed spectrum consideration; reliable physical layer transmission using multiple antennas; multichannel medium access protocols with QoS provisioning; wireless access topologies: point-to-point, point-to-multipoint, peer-to-peer multihop (mesh); wireless multimedia services: wireless IP-TV, wireless VoIP; mobility; cognitive radio technologies; advanced wireless security; wireless/wireline integration.

Benny Bing is an associate director of the Georgia Tech Broadband Institute. He has published over 40 papers and 10 books. His books on wireless networks are highly regarded by many technology visionaries. They contain forewords from both chairmen of the IEEE 802.11 Working Group since its inception, the inventor of Internet technology, and the inventor of the first wireless protocol. In early 2000, his groundbreaking book on wireless LANs was adopted by Cisco Systems to launch the Cisco-Aironet Wi-Fi product. The product has since enjoyed phenomenal success, dominating the corporate arena and capturing over 60% of the Wi-Fi market share. He was subsequently invited by Qualcomm Inc. in San Diego, CA to conduct a customized course on wireless LANs for its engineering executives. In 2002, his edited book on wireless LANs was extensively reviewed by the IEEE Communications Magazine, IEEE Network, and ACM Networker, the first time a book has been reviewed by all three journals. He is currently an editor for the IEEE Wireless Communications Magazine, and has also guest edited for the IEEE Communications Magazine and the IEEE Journal on Selected Areas on Communications.
