T1:  SIP and RIA

The SIP Tutorial includes an introduction to SIP and its associated protocols such as RTP (Real-time Transport Protocol) and SDP (Session Description Protocol). Both client-client server and peer-to-peer SIP systems are discussed. Various issues of working over the Internet, especially NAT (Network Address Translation) traversal are presented as well as SIP-specific solutions such as the STUN/TURN and ICE protocols. SIP security issues are is also presented. Examples of various SIP based communication applications are provided, in the areas of telephony, presence, instant messaging and multimedia.

The dominant VoIP (Voice over IP) standard protocol, SIP has initially been modeled after HTTP (Hyper Text Transport Protocol), but since then these two application protocols have developed quite differently: SIP has been embraced by the telecom industry while the Rich Internet Applications (RIA) on the web are a transformative driver for many industries. The tutorial discusses the potential of combining SIP with RIA in an homogenous manner, that includes applying web architectural principles to certain SIP systems.

T2: IPTV and the Future of Video Services

Service providers have been recently investing heavily in IP technologies with the goal of providing reliable, high-quality digital TV content to their subscribers with rich personalization features. This new form of television, called IPTV, leverages many existing networking architectures and protocol specifications, but also led the way to develop new ones to address its specific requirements.

In this tutorial, we provide a detailed overview of IPTV and its building blocks, explain the architectures and protocols used to carry video over IP in core, aggregation, access and home networks along with the current standardization efforts, and present observations and experiences from real deployments. The tutorial also touches on several concepts related to IPTV, including over-the-top services, Internet/Web TV, the TV Everywhere model and targeted advertising.

T3:   4G - Next Generation Mobile Applications

Emerging mobile platforms
Today, mobile handset processing power and functionality parallels that of laptop/desktop computers. Despite its limitations (battery life, screen size, and input), the mobile device is emerging as a major computing platform that fuels a major category of software applications. In this section of the tutorial, we will survey the existing fragmented state of the mobile platform space and discuss the key advantages and disadvantages of existing platforms.

Mobile 2.0 - Web 2.0 on mobile devices
Mobile 2.0 refers to the next generation of mobile broadband services that extend the social aspects of Web 2.0 (collaboration and sharing among users) to the mobile world. Today’s mobile device characteristics and capabilities take the social Web aspects of Web 2.0 to the next level by enabling
personal, always-on, and location-aware services. In this section of the tutorial, we will discuss the unique opportunities and challenges associated with Mobile 2.0 applications.

The mobile “cloud”
While many mobile applications are stand-alone and do not require any communications beyond that of the device itself, the more interesting class of mobile applications involves communications with services residing in the cloud. While most of these services are existing Web-based services (e.g., Google search, Yahoo local, Twitter, etc), several advanced and personalized services require a new class of “cloud” services. In this section of the tutorial, we will survey several of these mobile cloud services.

Location information as an enabler
Location plays an important role in our daily lives due to its unique ability to connect our surrounding physical world with digital information and content available for this physical world. Mobile devices are poised to become the primary delivery medium for a new generation of location-aware services. In this section of the tutorial, we will review positioning technologies for mobile devices and discuss their main strengths and weaknesses.

Location-aware services
Location-aware services are gaining a prominent role due to their game-changing potential. However, wide-spread acceptance of these services faces many technical, business, and psychological barriers. On the technical side, understanding the context in which mobile handsets are being used, the strengths and unique challenges of mobile handsets, and providing a simple and intuitive user interface are key factors in successful user adoption. On the business side, developing strategies for enabling advertisers and content/information providers and making the service available to a wide audience is required for profitable services. On the psychological side, enforcing strict security and data lifecycle management will ease user worries associated with the privacy of the information collected and shared by location-aware services. In this section of the tutorial, we will address the above challenges to some depth.

Mobile social networking
In this section of the tutorial, we will discuss social networking in the context of mobility. In particular, we will discuss some of the emerging mobile virtual worlds, mobile augmented reality, and life streaming applications.

Personal navigation applications
Today, personal navigation devices (PNDs) go beyond driving direction from point A to point B. For instance, they offer: Bluetooth connectivity with cellular phones for hands-free calling and accessing back-end services, built-on MP3 players, speech recognition and text-to-speech, a large database of Points of Interest, and access to online content and information in real-time (such as gas prices, movie listings, etc.). In addition, PNDs have started embracing user context and linking with popular social network sites. In this section of the tutorial, we will discuss current trends in the space of PNDs and address the emerging class of personal navigation applications running on mobile handsets.

Applications accessible through mobile devices, such as mobile phones, are playing an increasingly important part in the delivery of high quality and personalized healthcare services. Several efforts are under way to transform smartphones into computational and medical imaging devices. In this section of the tutorial, we will examine current usage of mobile devices and networks by mobile healthcare applications, and discuss how mobile devices and networks could be used for creating patient-centered healthcare applications.

T6: Towards Glitch-Free VoIP and Video Conferencing

Worldwide VoIP (voice over Internet protocol) service revenue was 24.1 billion USD in 2007, surged 52% over 2006. Both residential and business VoIP services experienced strong growth, with particularly stronger growth at the residential side, with revenue up 56%, and subscribers up 60%. It is predicted that VoIP service revenue would double over the next 4 years, reaching 61.3 billion USD in 2011, yielding an annual growth rate of 26%.

A key obstacle for VoIP to completely substitute PSTN (public switch telephone network) is VoIP’s current capability to provide quality and reliable service compared to PSTN. While the VoIP customers are cheering for its flexibility and efficiency, they are dismayed by its quality and reliability. Since VoIP call does not traverse a dedicated network like a PSTN or a cell phone network, the QoS (quality of service) of VoIP call depends on the capability of the application in managing the packet jitter, packet loss and addressing the possibility of unreliable bandwidth on the path. It is perceived that the QoS of VoIP is not only inferior to that of PSTN, but also to that of cell phone network.

In this tutorial, we take a close look at the VoIP and video conferencing system, from the system component, the audio/video component and to the network component. Through the tutorial, we hope that the students will gain a broad knowledge of the inner works of the state-of-the-art VoIP and video conferencing system. Moreover, the students will also learn various technologies in both codec and networking area that can be used to design a VoIP and video conferencing system with superior quality of service.ه

T7:ه Delay and Disruption Tolerant Networking

Delay and Disruption Tolerant Networkingه(DTN) is one of the research areas within mobile networking that have grown the fastest over the past few years. A lot of work have been done and published about DTNs, and DTN research has become gone from a small nich\'{e} area to a hot topic in many major conferences, including Mobicom, Mobihoc, Sigcomm, and Infocom. Work in this area address networking in environments where some of the implied assumptions of traditional network protocols cannot be met. These characteristics of the networks can include very long propagation delays and frequent disruptions in network links (meaning that there may never even exist a fully connected end-to-end path).ه Frequently, node mobility must be used to move messages through the network, with opportunistic communication contacts eventually allowing messages to be delivered to their destination.

Work in this area was initially begun to support interplanetary networking, but soon many terrestrial scenarios with similar characteristics were discovered. Such scenarios include communication in remote and rural areas and developing countries, vehicular communication, and sensor networks.

The very long delays and the lack of end-to-end connectivity means that traditional protocols that require frequent end-to-end interaction become unfeasible and thus there is a need for new communication architecture and application paradigms. Sessions should be bundled and send in single messages whenever possible, and applications must be designed such that they do not leave the user waiting indefinitely for an answer that may take a long time to be delivered.

In this tutorial we will give a background and motivation to the research area and show what the differences from traditional networks are. We will then provide an outline of the research that has been done in the area up to this point in different aspects of the system, as well as provide some case studies of real systems. Finally, future challenges for research in this area will be provided.ه We believe both practical implementation knowledge and deep understanding of the topics are important to give a tutorial. and both instructors have experience in both aspects, and thus, our tutorial would be highly beneficial to participants.

The ExtremeCom 2009 workshop was jointly organized by Dr. Lindgren and Dr. Hui and was the first of its kind in bringing the researchers into the environment for which they are designing the delay tolerant systems. The workshop was arranged in a remote area of the Swedish mountain and included 4 days of hiking as well as paper presentations and technical discussions. Participants could experience the target environment for a DTN system and meet and discuss with intended end users. The workshop was very successful and all participants found the attendance highly rewarding.

T8:㺹㺹㺹 Wireless Broadband Networks Technologies

Wireless access network standards are diverse as each is optimized for different category of usage, whereas their core network provides opportunity for convergence. The major wireless network standards include those in the 3GPP (3rd Generation Partnership Project) family, 3GPP2 family, and the wireless networks under IEEE 802 family. The number of mobile subscriptions worldwide continues to grow and had reached 4 billion, out of which about 85% are GSM. The 3GPP family takes advantage of the dominance of GSM phone and provides evolution path for cellular phones while also providing access to other wireless networks. It evolves GSM in 2G Wireless to Beyond 3G, and to 4G. The radio access network had evolved to UTRA and WCDMA in 3G Wireless, to HSPA and HSPA+ in Beyond 3G Wireless, and then to Long Term Evolution (LTE). The core network had evolved to UMTS network and then to Evolved Packet Core (EPC) as it moves to all-IP network supporting different access networks with many different services and yet to reduce complexity with fatter network. The 3GPP2 also has an evolution path, but EPC core network is providing access to 3GPP2 access networks, EPC will become the convergent core network for both 3GPP and 3GPP2.

With the convergence of wireless networks, wired networks, and broadcast networks, the wireless networks are evolving fast towards 4G wireless and beyond. ITU has defined the requirements in IMT-Advanced to provide the standard for 4G Wireless. The 3GPP system of EPC, LTE+ and Femtocell is expected to be a strong player in 4G Wireless. The tutorial overviews the key concepts and understanding of the architecture, requirements, challenges, future trends, and the key issues affecting operator decisions.
