Analysis of Delay, Capacity, and Capacity Deficit in Multihop
Thu, Sep 28, 2006 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Dr.Nabhendra Bisnik - Rensselaer Polytechnic InstituteMultihop wireless networks, such as wireless ad hoc, sensor, and mesh networks, have applications in a variety of fields like providing connectivity to communities, surveillance, monitoring, defense, etc. However scalability of such networks is marred by scarce bandwidth, broadcast nature of the wireless medium, and dynamic nature of network topology due to node mobility. In this talk we present analytical techniques for characterizing delay, capacity, and the capacity deficit caused by routing protocol overheads. We present a queuing theory approach to evaluate average end-to-end delay and maximum achievable per-node throughput in random access MAC based wireless ad hoc and mesh networks. The model takes into account the number of nodes, the random packet arrival process, the extent of locality of traffic, and the backoff and collision avoidance mechanisms of random access MAC. We model the random access multihop wireless networks as open G/G/1 queuing networks and use the diffusion approximation method for evaluating closed form expressions for average end to end delay. In order to characterize the impact of routing overheads on the actual capacity available to network users for transmitting data we present an information theoretic framework for analyzing the minimum routing overheadincurred by geographic routing in mobile ad hoc networks. We formulate the minimum routing overhead problem as a rate distortion problem and evaluate a lower bound on the minimum routing overhead incurred for routing packets with desired level of reliability. We characterize the effective transport capacity of ad hoc networks available to the users for transmitting data, after taking into account the minimum overheads that must be incurred for reliable routing. We also present results on the critical network size, above which the entire transport capacity of the network may be consumed by the routing overheads

Mork Family Department of Chemical Engineering and Materials Science
Conferences, Lectures, & Seminars
Ultrafast Biological Dynamics at Atomic Scale Dongping ZhongDepartments of Physics, Chemistry and Biochemistry,
Programs of Biophysics, Chemical Physics and Biochemistry,
The Ohio State University, 191 West Woodruff Avenue, Columbus, OH 43210, USAProtein dynamics is a complex process and the current challenge is to break down its complexity into elementary processes which act on different time scales and length scales. We integrate femtosecond spectroscopy, molecular biology techniques, and computational simulations to study functional evolution in real time and thus elucidate the complex dynamics with unprecedented detail. Here, two important biological systems, protein surface hydration and light-driven DNA repair, will be reported. With femtosecond temporal and single-residue spatial resolution, we mapped out the global water motion in the hydration layer using intrinsic tryptophan residue to scan the protein surface with site-directed mutagenesis. The results reveal the ultrafast nature of surface hydration dynamics and provide a molecular basis for protein conformational flexibility, an essential determinant of protein function. For DNA repair, we followed the entire functional evolution through femtosecond synchronization. We resolved a series of ultrafast processes including active-site solvation, energy transfer, and electron tunneling. These results elucidate the crucial role of ultrafast dynamics in control of biological function efficiency and lay bare the molecular mechanism of DNA repair at atomic scale.

Spotlight on Biomedical Engineering
Thu, Sep 28, 2006 @ 06:00 PM - 07:00 PM
Viterbi School of Engineering Student Affairs
Workshops & Infosessions
The Viterbi Spotlight Series is a NEW series of panel presentations designed to help first year engineering students learn more about the majors in Viterbi. Each major will be highlighted once throughout the fall semester. Whether you are an undeclared engineering student or still not sure what engineering is all about, feel free to come to every session of the "Spotlight Series" to help educate yourself about the various areas of study that are available to you. Panelists will include faculty, industry representatives, current students and Viterbi alumni.Please RSVP: http://viterbi.usc.edu/fye
