Tutorial 3: Exploiting Smart Beamforming Antennas in Wireless Ad hoc Networks

Sunday Morning, May 2
8:00AM - 12:00PM
Marriott Hotel

Presented by

Osama Bazan - Ryerson Univesity


The use of smart beamforming antennas in wireless ad hoc networks has recently received increasing attention in the networking community due to their potential benefits and numerous advantages over the traditional omni-directional antennas. Beamforming antennas have the ability to increase the spatial reuse, reduce the interference, improve the transmission reliability, extend the transmission range and/or save the power consumption. If they are effectively used, they can significantly improve the network capacity, lifetime, connectivity and security; which make them important technology for future wireless networks. However, their use in multi-hop wireless networks introduces unprecedented challenges, such as deafness and directional hidden terminals, which need to be carefully addressed at the upper layers in order to exploit the offered potential. This half-day tutorial will provide a comprehensive overview of the design and implementation issues of the antenna-aware network protocols mainly at the medium access and networking layers. We will address the benefits as well as the challenges of using beamforming antennas in multi-hop wireless networks. The tutorial will present the state-of-the-art solutions in directional MAC and directional routing protocols that are designed to harness the potential benefits of beamforming antennas. Where important, performance results will be presented. Theoretical capacity bounds and some practical aspects will also be discussed. We will conclude the talk by highlighting open research work.

Presenter's Biography

Osama Bazan is a Post Doctoral Fellow in the Department of Electrical and Computer Engineering at Ryerson University since January 2009. He received his Bachelor (BSc.) and Master (MSc.) Degrees in Electronics and Electrical Communications Engineering from Cairo University, Egypt in 2000 and 2003 respectively and his PhD degree in Electrical and Computer Engineering from Ryerson University, Canada in 2009. Osama has authored several papers published in leading journals and conferences on the topic of "Using beamforming antennas in wireless ad hoc networks". He is a member of IEEE, IEEE ComSoc and some of its technical committees. Osama served as technical program committee member for several international conferences and as a peer reviewer for numerous journals and conferences. His research interests include MAC and routing in ad hoc networks, multi-hop wireless networks with heterogeneous antennas and interference-aware routing in wireless mesh networks.
