About the Author
Dr. Dharma P. Agrawal is the Ohio Board of Regents Distinguished Professor of Computer Science and Computer Engineering in the Department of Electrical and Computer Engineering and Computer Science at the University of Cincinnati. Previously, he was a faculty member at Wayne State University (1977-1982) and North Carolina State University, (1982-1998). He has been a consultant to the General Dynamics Land Systems Division, Battelle, Inc., and the U. S. Army. He has held visiting appointment at AIRMICS, Atlanta, GA, and the ATandT Advanced Communications Laboratory, Whippany, NJ. Dr. Agrawal has published a number of papers in the areas of Parallel System Architecture, Multicomputer Networks, Routing Techniques, Parallelism Detection and Scheduling Techniques, Reliability of Real-Time Distributed Systems, Modeling of C-MOS Circuits, and Computer Arithmetic. Recent research interests include energy efficient routing, information retrieval, and secured communication in ad hoc and sensor networks, effective handoff handling and multicasting in integrated wireless networks, interference analysis in piconets and routing in scatternet, use of directional antennas for enhanced QoS, Scheduling of periodic real-time applications and automatic load balancing in heterogeneous workstation environment. Dr. Agrawal has four approved patents and five patent filings in the area of wireless cellular networks. He received a D.Sc. from the Swiss Federal Institute of Technology in Lausanne, Switzerland. He is Fellow of the IEEE and the ACM.
This is the first Wireless and Mobile Systems text written for Computer Science and Engineering students (as opposed to Electrical Engineering graduate students). The authors explain the general principles of how wireless systems work, how mobility is supported, what is the underlying infrastructure and what interactions are needed among different functional components. Appropriate for undergraduate or graduate courses, the chapter topics focus on qualitative descriptions and the realistic explanations of relationships between wireless systems and performance parameters. Rather than offering a thorough history behind the development of wireless technologies or an exhaustive list of work being carried out, the authors help EE and CSE students learn about this exciting technology and understand how a cell phone starts working as soon as they get out of an airplane.
