Title: Wireless Sensor Networks Speaker: Ian F. Akyildiz, Georgia Institute of Technology, USA Duration: FULL DAY (Monday 22 june 09) http://www.ece.gatech.edu/research/labs/bwn
Summary: The technological advances in the micro-electro-mechanical systems and the wireless communications have enabled the deployment of the small intelligent sensor nodes at homes, in workplaces, supermarkets, plantations, oceans, streets, and highways to monitor the environment. The realization of smart environments to improve the efficiency of nearly every aspect of our daily lives by enhancing the human-to-physical world interaction is one of the most exciting potential sensor network applications utilizing these intelligent sensor nodes. However, this objective necessitates the efficient and application specific communication protocols to assure the reliable communication of the sensed event features and hence enable the required actions to be taken by the actors in the smart environment. In this tutorial, the challenges and the existing solutions for the design and development of sensor network communication protocols are presented. More specifically, application layer, transport layer, network layer, data link layer, in particular, error control and MAC protocols, and physical layer issues as well as the cross layer solutions, localization protocols and the time synchronization algorithms are explained in detail. Open research issues for the realization of sensor and actor networks are also discussed. The overall objective of this tutorial is to provide a global and detailed view at the current state-of-the-art in WSNs and present the still-open research issues and point out the research challenges for the next generation sensor networks such as multimedia, underwater and underground applications. The topics covered include: Architecture and Protocol Stack Factors Influencing WSNs Applications Application Layer Transport Layer Routing Algorithms Medium Access Control Error Control Physical Layer Cross Layer Solutions Localization Algorithms Time Synchronization Wireless Sensor and Actor Networks (WSANs) Wireless Multimedia Sensor Networks Wireless Underwater Sensor Networks Wireless Underground Sensor Networks The intended audience includes faculty, engineers, end users, and students, interested in sensor networks.

Peer-to-Peer Networking : State of the art and research challenges Prof. Raouf Boutaba Duration: HALF DAY (Friday 26 june 09) University of Waterloo - Ontario, Canada
Summary: The past few years have witnessed the emergence of Peer-to-Peer (P2P) systems as a means to further facilitate the formation of communities of interest over the Internet in all areas of human life including technical/research, cultural, political, social, entertainment, etc. P2P technologies involve data storage, discovery and retrieval, overlay networks and application-level routing, security and reputation, measurements and management. This tutorial will give an appreciation of the issues and state of the art in Peer-to-Peer Networking. It will introduce the underlying concepts, present existing architectures, highlight the design requirements, discuss the research issues, compare existing approaches, and illustrate the concepts through case studies. The ultimate objective is to provide the tutorial attendees with an in-depth understanding of the issues inherent to the design, deployment and operation of large-scale P2P systems. Presenter: Raouf Boutaba is a Professor of Computer Science at the University of Waterloo and a David R. Cheriton faculty fellow. Before that he was the Director of the Telecommunications and Distributed Systems Division of the Computer Science Research Institute of Montreal. He held Visiting Professor Positions at the University of Toronto (Canada), the University of Pierre et Marie Curie, the University of Versailles, ENST- Paris, Paris 13 and Paris 5 (France), and POSTECH (Korea). He is currently a distinguished speaker of the IEEE Communications Society and served in the past as a distinguished speaker of the IEEE Computer Society.

Challenges in Network Virtualization Dr Omar Cherkaoui Duration: HALF DAY (Friday 26 june 09) University of Montreal,Canada
Summary: This tutorial provides an overview to the discipline of Network Virtualization (NV). Previously, Network Virtualization has consisted in deploying network services (VLAN, VPN, etc) and today it has evolved in the deployment of multiple distinct networks over the same physical infrastructure. Each network instance requires a level of isolation from the other instances. This isolation uses some old OS concepts of virtualization like: Hypervisor (VMM) and Containers. Furthermore, those concepts use an independent layer for the control and sharing of resources like network links, CPU, memory, interfaces, etc. Virtualization has emerged as an active research area. Many large research projects (GENI, 4ward, Federica, Clean Slate, Horizon, JGN2 Japan) have been launched during the last two years. Those initiatives mainly try to develop the next generation network based on the network virtualization concept. Network virtualization will require resolving many research issues and challenges. We need to know where to push this virtualization: on which network/equipment and at which layer (L3/L2/L1)? We also need to determine the right trade-off between isolation, performance and flexibility of migration. It means that we need to decide where to push virtualization: at the data plane, control plane or management plane. Another approach is to determine if virtualization needs to be established at the hardware level, OS level or service level. New Infrastructure virtualization architectures need to be developed. Resource allocation algorithms will have to be adapted to the network virtual instances. This virtualization also adds a new level of configuration complexity that requires resolution. We will review the way the main architectures proposed by the different projects like GENI, VINI, Find, Clean slate, Horizon, etc. handle those virtual slices and instances. We will expose different migration strategies in order to offer resiliency and reliability in this new virtualized environment. Outline including a short summary of every section 1. Why we need the virtualization in the network? 2. Which Virtualization? Micro-kernel (Type I) vs Containers (Type II) VMM (Hypervisor) 3. Where we can push this virtualization? On which network/equipment? On which layer (L3/L2/L1)? Business case 4. Open Research Issues in Network Virtualization Isolation vs Performance: virtualization at the data plane, control plane or management plane Virtualization at Hardware level, OS level or service level Infrastructure virtualization architecture; Resource allocation to virtual instance; Configuration complexity for infrastructure virtualization Projects on network virtualization 6. Security issues with virtualized infrastructure. Potential attendee profile : This tutorial/course is intended for researchers (and students) in the field of network management of virtualized network. The tutorial/course is also useful to industry professionals that wish to have a system/technology based analysis of the current and emerging virtualized network architecture evolution.
