Tutorials Information

Tutorial 1.
"Using Information Fusion in Wireless Sensor Networks: The State-of-the-art and challenges"

The fast growth in wireless sensors and actuators have the potential to create a global computing infrastructure that is pro foundly changing the way people live and work. People may interact with themselves, the physical world, and information services using a wide range of sensor devices connected together, enabling computing and communication at an unprecedented scale and density. This new infrastructure presents a number of challenges, especially when it comes to data-intensive applications: large scale, dierent types of data, data processing and management, varying and intermittent connectivity, location dependence and context awareness, limited bandwidth and power capacity, small device size, and multimedia delivery across diferent networks.

This tutorial will present a perspective on information fusion to be employed in wireless sensor networks. The goal is to present the different aspects (theories, tools, and algorithms) of information fusion considering a data management perspective.

Tutorial 2.
"Community Mesh Networks:From Theory to Applications"

Wireless Mesh Networks (WMN) are wireless multi-hop networks that offer an attractive alternative for providing rapid and cheap broadband wireless internet connectivity, especially for localized and community aware communication. They present a paradigm shift from current internet architecture towards a totally decentralized, self-managed, scalable and adaptive wireless access network eliminating the need for cables. The application potential of WMNs is enormous including scenarios like emergency communications, home networks, community and neighborhood networking and services, enterprise networks or carrier grade mesh networks. Key challenges in WMN research are to increase capacity and frequency diversity by developing multi-channel, multi-radio MAC and routing protocols enabling a decentralized adaptive radio resource management. Cross-layer design in particular involving physical layer, MAC layer, and routing protocols is essential for an efficient operation. Delivering carrier-grade quality requires a proper planning and dimensioning of WMNs, resilient routing helps to increase the survivability of the network in case of failures.
This tutorial will give an overview on state of the art in WMN research, identifying key research challenges and solution proposals for current hot topics. Trends in standardization are illustrated together with ongoing projects and testbed deployments. A general classification of WMNs will be introduced and put into relation with IEEE 802.11s and IEEE 802.16 mesh and relay mode.

Tutorial Content Description:
This tutorial provides a comprehensive overview on principles behind WMNs, practical solutions as developed by relevant industry, and standardization issues. We first introduce the concepts of WMNs and give an overview on deployment scenarios focusing on localized communication in communities as well as applications and services foreseen for such mesh networks. Different types of WMN technologies will be identified and classified according to their main functionality like signaling, resource allocation, and routing. We will then systematically cover research issues and challenges associated with several layers in WMNs, especially in relation to the following topics: Capacity, Topology Control and Interference; Channel Assignment for Multi-Channel Multi-Radio WMNs; Medium Access Control; Routing; Congestion Control; Fairness and Cooperation; and Quality of Service Provisioning. Furthermore, we will discuss planning and optimization issues in WMNs. Here the challenge arises how to plan a self-organizing network. We then provide a detailed description of important architectural solution proposals from industry and academia that will capture the current state of the art in this area, including available testbeds and deployments such as Roofnet or Freifunk. This will lead to a presentation and discussion of several open research challenges to foster the development of novel research ideas in the attendees. We finalize the tutorial by presenting current standardization efforts in relation to 802.11s WLAN meshes and 802.16 WiMAX mesh and relay operation. The main differences between the solutions and their usefulness for different application scenarios will be discussed.

Learning Outcomes:
After attending this tutorial, attendees will have a clear understanding of basic principles behind Wireless Mesh Networking and open research issues. Therefore, participants will be able to evaluate future developments and trends in this area. Attendees will also have an overview on ongoing standardization activities. The knowledge gained through this tutorial will help researchers and engineers to build better algorithms, protocols and services for WMNs. As several research issues involve several layers, it is important to gather different domain experts together. Therefore, MSWiM is seen as an excellent venue for this tutorial as it attracts experts from different fields related to wireless mesh networks – from mobile systems, wireless access, algorithms and up to application level. Discussion among such experts as part of this tutorial will help to catalyze novel ideas spanning several domain areas. The major goal of the tutorial is to provide the attendees with a general understanding of the functionality, the potential, and the challenges of WMNs without losing the connection to current mesh technologies.

Tutorial 3.
"Cognitive Radio Networks"

Existing wireless networks are characterized by a fixed spectrum assignment policy. However, it is well known that a consistent portion of the assigned spectrum is used sporadically and geographical variations in the utilization of the assigned spectrum range from 15% to 85% with a high variance in time. The limited available spectrum and the inefficiency in spectrum usage call for a new networking paradigm based on more flexible opportunistic utilization of the existing wireless spectrum. This new networking paradigm is referred to as cognitive radio network. In this tutorial, the new functionalities and current research challenges of cognitive radio networks are outlined and discussed in detail. More specifically, an overview of the cognitive radio technology is provided and key network architectures are introduced. Moreover, the main cognitive network functionalities such as spectrum sensing and decision, spectrum mobility and spectrum sharing are analyzed in detail. The influence of these functionalities on the design and performance of medium access control and upper layer protocols such as routing and transport are discussed. Furthermore, cross-layer design and other open research issues are covered in detail. Finally, current standardization and experimental activities are outlined.

Tutorial 4.
"Intelligent Vehicular Networks"

The last few years have witnessed an unmistakable converge of Intelligent Transportation Systems (ITS) and Vehicular Ad hoc NETworks (VANET) leading to the emergence of Intelligent Vehicular Networks that promise to revolutionize the way we drive by creating a ubiquitous safe and secure environment that will eventually pervade our highways and city streets. Being at the confluence of ITS and VANET, research in intelligent vehicular networks finds inspiration and borrows ideas from both these areas.

This tutorial has for stated goal to provide a succinct survey of the state-of-the-art contributions on the design, specification, and implementation of architectures and protocols for current and future applications of the intelligent vehicular networks.

The tutorial proposes to be self-contained defining all basic terms and concepts and should be accessible to all those with a minimal exposure to networking.

Tutorial 6.
"Mobility Modeling for Future Mobile Network Design and Simulation"

Future networks will consist of numerous wireless devices, many of which will be mobile. With the proliferation of handheld devices that are tightly coupled with our everyday life, human mobility is likely to play a key role in designing and evaluating efficient networks and services of the future. A new generation of infrastructure-less networks is being introduced, including ad hoc, sensor and delay tolerant networks that will rely heavily of mobile nodes for connectivity and communication establishment. Also, with the introduction of vehicular networks, it will be imperative to model and understand vehicular mobility patterns. Hence, there is a compelling need to study, analyze and understand mobility models in order to have valid evaluation tools for future mobile protocols, networks and services. This tutorial discusses issues of mobility modeling, focusing on ‘realistic’ aspects traditionally ignored in random models (such as random walks, or random way point). The tutorial has two main parts. The first part starts from the classification of major mobility models, establishes a framework (called
IMPORTANT) to systematically analyze such models and walks through several key studies that motivate the need for new models. By evaluating the effects of mobility on several classes of future mobile networks and protocols (e.g., ad hoc and encounter routing protocols) the tutorial provides insight into the shortcomings of conventional (random) models and introduces another rich set of models (e.g., Group, Freeway, Manhattan). Focus is given to two main questions: Why and how does mobility affect routing performance? The second part of the tutorial utilizes extensive measurements of existing wireless networks (mainly WLANs and Bluetooth) to establish a more realistic set of mobility models based on time-varying communities (TVC). Insight established from the analysis is utilized to design a new efficient communication paradigm called ‘profile-cast’ for mobile social networks. Various tools for mobility modeling and simulation are also referenced and discussed.
