Speaker Bio

Dr. Waltenegus Dargie is a senior researcher and the head of Energy Lab at the Faculty of Computer Science, Technische Universität Dresden, Germany. He is the recipient of two German Research Foundation (DFG) projects and was a PI in an additional prestigious DFG project (2011-2019). He holds a PhD in Computer Engineering from the Technische Universität Dresden (2006) and a MSc in Electrical Engineering from the Technische Universität Kaiserslautern (2002). His research focus is on developing smart computing and sensing systems and on applying unsupervised learning to extract meaning from sensed data. Waltenegus is an accomplished writer, publishing four novels and one philosophical nonfiction which examines the life-philosophies of Albert Einstein, Fyodor Dostoevsky, Leo Tolstoy, and Sigmund Freud.

Abstract

Deploying distributed and self-organizing wireless sensor networks in areas which are remote, dangerous, extensive, or inaccessible to human beings enables safe and flexible monitoring of these areas. Two of the most formidable challenges towards this goal are (1) producing sensor nodes which endure and operate in rough environments and (2) establishing reliable wireless links between nodes to establish resilient networks. In this talk the speaker shares his experience with deploying wireless sensor networks in different water bodies — on a lake at FIU’s Main Campus, North Biscayne Bay, Crandon Beach, and South Beach, Miami, Florida. The talk addresses pre-deployment issues (such as the choice of waterproof boxes and energy sources) and the impact of extreme weather conditions (excessive heat and rainfall); the movement of water; and cross-technology interference (CTI) on the performance of the networks.
