Profs to Help Develop Instantly Deployable Networks
Two UT Dallas computer science faculty will be working closely with AgileMesh Inc., a North Texas company that has received $2 million from the Texas Emerging Technology Fund (TETF) to further develop its technology. “We will be helping AgileMesh build technology in the area of mobile ad hoc networks, an area of wireless networks that enables instant deployment,” said Dr. S. Venkatesan, an associate professor of computer science in the University’s Erik Jonsson School of Engineering and Computer Science. “This has immediate application in disaster areas, rescue efforts and other situations in which installed communication infrastructure does not exist or is inadequate.” Venkatesan and Dr. Ravi Prakash, also an associate professor of computer science, have more than 30 years of experience in the field. They’ll be developing methods that enhance AgileMesh’s products by significantly improving usability and performance.
Computer Science Prof Emphasizes Relevance
More than 95 percent of the students in Subbarayan Venkatesan’s Advanced Computer Networks class last fall ranked his course as good, very good or excellent – a pretty good indicator to any oddsmakers that students might vote him their favorite computer science instructor for the just-completed academic year. Which they did. Several students said they look forward to each of Dr. Venkatesan’s computer science classes, and one explained exactly why: “Prof. Venky (as we call him) breaks down the toughest subjects and concepts into such simple elementary components that, when all is said and done, nothing is impossible.” No newcomer to academia, Dr. Venkatesan, an associate professor of computer science, has been perfecting his teaching technique at UT Dallas for two decades.
