Overview:

This tutorial has three major goals:

To give the attendees a brief overview of the considerable body of literature devoted to algorithmic and theoretical approaches in wireless ad hoc and sensor networks and their connectivity to the Internet.
To provide the attendees with an introduction to a network simulator (ns2), i.e., with the expertise needed in the analysis of mechanisms for wireless ad hoc and sensor networks.

To outline the limitations of the current models for wireless networks, and to bridge the gap between the theoretician and engineers

Place and Date:

Faculty of Engineering, Shiraz University, Shiraz, Iran, Friday Sept. 9, 2005.

Audience:

this tutorial is appealing for researchers with both a computer science and engineering background in academia, as well as for people from the mobile and personal communication industrial community. Engineers, Msc/PhD students, researchers and project managers that would like to have a deeper understanding of the issues and challenges and opportunities related to self-organising wireless mobile networks, wireless sensor networks and tools to test the related protocols should attend this tutorial. Graduate and undergraduate students, and any professional who is interested in entering into this fundamental field of wireless ad hoc and sensor networking research, are especially welcome.

Teacher's Biography:

Mona Ghassemian obtained her B. Eng degree from Ferdowsi University in Iran in 1999 in the field of control and instrumentation design. Later she studied as a taught Msc student at Iran University of Science and Technology for a year and received her Msc by research at King's College London (KCL) in September 2001. She started her PhD at Centre for Telecommunications Research (KCL) with the support from Ntt DoCoMo Japan with collaboration for DoCoMo Euro lab in Munich. She is currently writing up her thesis on multihop radio access networks.

Her areas of interest are mainly on ad hoc networks and different aspects of Internet connectivity for such networks. She has published and presented her research outcomes at International Telecommunications conferences.
