Joon Ahn Ph.D. Student (EE) Contact: Email: joonahn at usc dot edu http://anrg.usc.edu/~joonahn

Research Interest My research interest lies on the performance analysis, protocol design, mathematical modeling of computer networks. Particularly, I am now working on the analysis of system behavior in terms of energy consumption and/or throughput using stochastic analysis and geometry for wireless sensor networks. I'm hopping to devise nice protocols and/or algorithms based on the intuition attained by those analyses.
