       (Monday, July 16th,  Full day)


Nitin Vaidya
Texas A&M University
College Station, TX 77843-3112

A mobile ad hoc network is a collection of mobile wireless nodes that can dynamically form a network without necessarily using any pre-existing network infrastructure. In general, routes between nodes in an ad hoc network may include multiple hops. Due to the potential ease of deployment, many practical applications have been conceived for ad hoc networks, including personal area networking, home networking, search-and-rescue operations, and battlefield applications.
When designing mobile ad hoc networks, several interesting and difficult problems arise due to shared nature of the wireless medium, limited transmission range of wireless devices, node mobility, and battery limitations. This tutorial will present an overview of issues related to medium access control (MAC), routing, and transport in mobile ad hoc networks, including interaction between the different layers of the protocol stack. Techniques proposed to improve performance of MAC, routing and transport protocols will be discussed. The tutorial will include a discussion of approaches for reducing energy consumption by nodes in a mobile ad hoc network. Some security-related issues will also be considered. In addition, the tutorial will discuss implementation-related problems, and mechanisms for integrating a mobile ad hoc network with existing wired networks. Finally, the tutorial will also present an overview of some standards activities related to ad hoc networking.

Tutorial 8: Bluetooth: Technology, Application, Performance
(Tuesday, July 17th, Morning)

Prof. Mario Gerla
University of California, Los Angeles

Per Joahnsson
Ericsson Research

Today, most mobile professionals travel with cellphone and laptop, and often need to interconnect them to browse the web or send e-mail. After getting entangled with cables,  they soon appreciate the convenience of interconnecting all personal devices instantly and wirelessly in a personal LAN (PAN). This is the first type of application – cable replacement – that has driven the development of the Bluetooth wireless LAN, an extremely versatile, low cost network interface soon to be installed in all personal devices (from cellphone and cameras to earphones). From the initial cable replacement concept based on the Piconet, the range of Bluetooth applications has quickly expanded to more challenging scenarios including: ad hoc networking among several personal Piconets; access to the Internet (via a repeater on the wall), and; pervasive, “unconscious computing”, ie, interaction between mobile user and the environment, through devices such as parking  meters and airport check in counters.  This broad set of applications in part overlaps with those of several other wireless technologies (IEEE802.11, UMTS, HomeRF, DECT, IrDa, etc). It is thus of interest to understand how Bluetooth will replace/complement (or be integrated with) existing systems. To properly compare technologies, it will be necessary to develop performance models. One of the goals of this tutorial is to introduce Bluetooth performance models and simulation tools, and their application to representative scenarios. The tutorial will begin with a review of the Bluetooth technology with emphasis on lower layers (physical, MAC and network), that have the most impact on performance. It will identify representative scenarios for typical Bluetooth application areas (from cable replacement to unconscious computing) and derive the relevant performance measures. It will then introduce newly developed performance evaluation methods and (simulation) tools and apply them to simple case studies. 

Part 1:
-Bluetooth Technology:
-lower protocol layers: radio, physical, MAC, Piconets, low power operation, 
-network layers: scatternets, discovery, ad hoc routing, handover 
-Bluetooth middleware
-State of standards (Bluetooth SIG); current implementations; test kits.
Part 2:
-Applications: identification of representative scenarios (eg, shopping center, exhibition hall, etc) and definition of relevant performance measures
-Bluetooth performance evaluation tools: simulation models (NS-2 and Parsec/Glomosim); 
-Case studies: indoor access to the Internet; ad hoc networking/scatternets; 

Intended Audience:
This tutorial will provide the background information and the performance methods and tools that can assist researchers, device manufacturers, wireless network operators, mobile applications developers and mobile users to evaluate the Bluetooth technology and assess its use in their applications.
