Cylab Supported Paper among Top 100 Cited by IEEE Xplore
10/24/2008
A paper published by two former ECE PhD students Sooksan Panichpapiboon and Nawaporn Wisitpongphan of Professor Tonguz, Dr. Gianluigi Ferrari, and ECE Professor Ozan Tonguz is one of the top 100 papers accessed in the IEEE Xplore in the month of June 2008 [PDF]. The paper entitled “Route Reservation in Ad Hoc Wireless networks” was published in the January 2007 issue of the IEEE Transactions on Mobile Computing.
The paper investigates under which conditions (in terms of route discovery, MAC protocol, pipelining, etc.) reserving a route in ad hoc wireless networks might be superior compared to non-reservation based schemes. While most wired networks use non-reservation-based switching and communication paradigms such as packet switching, it is shown in the paper that certain real-time applications such as voice and video using a route-reservation based communication scheme might yield better performance in terms of delay. The paper also proposes a new queuing-theoretic model for investigating the performance of non-reservation based communications in ad hoc wireless networks.
Dr. Sooksan Panichpapiboon is now a faculty member in the School of Engineering of King Mongkut Institute of Technology in Thailand, while Dr. Wisitpongphan is a Research Associate in the R&D of General Motors in Detroit. Dr. Gianluigi Ferrari who was a postdoc in the research group of Prof. Tonguz at the time this work was done is now an Assistant Professor in the Department of Information Engineering of the University of Parma in Italy.
The research reported in this paper was supported in part by a grant from Cylab.
Special Issue on Vehicular Networks
08/27/2008
Prof. Tonguz was recently invited to serve as the Managing Guest Editor of a Special Issue of AD HOC NETWORKS JOURNAL (Elsevier) on Vehicular Networks. The Special Issue aims to meet the growing research demand in vehicular ad hoc networks, a hot topic of great interest to car manufacturers and Departments of Transportation in the US and Europe. Two other General Motors researchers, Dr. Cem Saraydar and Dr. Fan Bai, will assist Prof. Tonguz as Guest Editors for making the Special Issue a major platform where the state-of-the-art research results of transportation industry and academia will be published. The Call For Papers for the Special Issue can be found here. The paper submission deadline for the Special Issue is December 1, 2008. For further information, please contact Prof. Tonguz.
A Recent Paper Ranked in the Top 10 Most Accessed Articles List in the IEEE Wireless Communications Magazine
08/13/2008
A recent CMU-GM paper published by Prof. Tonguz and his PhD student Hsin-Mu (Michael) Tsai in the IEEE Wireless Communications Magazine in December 2007 made the TOP 10 ARTICLES list in the most accessed documents of IEEE Wireless Communications Magazine in the month of April 2008 [PDF]. The paper co-authored by GM researchers Cem Saraydar, Tim Talty, and Andrew Macdonald reports the results of a comprehensive experimental study on the use of ZigBee technology for building an intra-car wireless sensor network.
As the number of sensors used in contemporary cars are rapidly increasing, there is a growing interest in replacing the wires used to connect these sensors to the CAN network with wireless technology. It is anticipated that the success of this research effort could lead to: 1) an open network architecture for placing more sensors in future cars; 2) better fuel efficiency because of the reduction in weight of cars; 3) a possible reduction in the overall cost of cars.
IEEE INFOCOM MOVE 2008
