A communications scientist who specializes in wireless sensor networks, since 1998 he has been the Ohio Board of Regents Distinguished Professor of Electrical Engineering and Computing Systems at the University of Cincinnati in Ohio, U.S.. He has published work on wireless sensor networks and ad-hoc computing, and was one of the editors of the Encyclopedia on Ad Hoc and Ubiquitous Computing in 2009. His research interests include applications of Sensor Networks in monitoring various diseases and physical conditions as well as secured communication in Vehicular Networks and use of Femto cells in LTE technology. In the telecommunications area, a Femtocell is a small, low-power cellular base station, typically designed for use in a home or small business. It connects to the service provider’s network via broadband (such as DSL or cable), allowing service providers to extend service coverage indoors or at the cell edge, especially where access would otherwise be limited or unavailable. He led the University of Cincinnati - BlueTooth (UCBT) Bluetooth package. UCBT an ns-2 based Bluetooth network module which simulates the Bluetooth network operations in great details. Most specifications at Baseband and above like LMP, L2CAP, BNEP have been simulated in UCBT, including frequency hopping scheme, device discovery, connection set up, Hold, Sniff and Park modes management, role switch and multi-slot packet type negotiation, SCO voice connection, etc. There is a provision to constitute a cluster of Bluetooth devices and such formation with up to 8 Bluetooth devices is known as a piconet. It also allows a number of piconets to be connected together using "bridge nodes" and such a large network is usually referred to as a scatternet. Bluetooth is widely used in cell phone, PDA, laptop, headset, printer, etc. to form a Personal Area Network (PAN) and provide universal access. He is a Fellow of the National Academy of Inventors, the Institute of Electrical and Electronics Engineers, the Association for Computing Machinery, the American Association for the Advancement of Science and the World Innovation Foundation. He received the Third Millennium Medal of the IEEE Computer Society in 2000 and the Harry H. Goode Memorial Award of the same society in 2008, “for Outstanding contributions and leadership in wireless and mobile systems, including ad-hoc, sensor, and mesh networks.". He was a Fulbright Senior Specialist (2002–2007), and was on the ISI Highly Cited Researcher list in 2001. He received the Hind Rattan of the NRI Welfare Society of India in 2011. He has published over 650 articles, including, with Qing-An Zeng ,“Introduction to Wireless and Mobile Systems, ISBN-13: 978-1439062050. He has given 29 keynote speeches, 42 intensive courses, and has supervised 70 Ph.D. dissertations. He is the holder of 7 patents and 25 invention disclosures, and in 2013 he was named a charter fellow of the National Academy of Inventors.
Noted For:Leader of the University of Cincinnati - BlueTooth (UCBT) Bluetooth package – Bluetooth is widely used in cell phones, PDAs, laptops, headsets, printers, etc.
