Holger Karl is currently assistant professor in the Networking Group (Prof. Adam Wolisz) at the Technical University of Berlin. His research interests focus on wireless and mobile networks, with a certain emphasis on ad-hoc networks. He has published numerous papers and research articles in international journals (e.g. IEEE, IEE, CPE). Andreas Willig is currently assistant professor at the University of Potsdam. His areas of interest comprise communication networks (wireless LANs, real-time systems and ad-hoc and sensor networks) and performance evaluation.
"""I am deeply impressed by the book of Karl & Willig. It is by far the most complete source for wireless sensor networks...The book covers almost all topics related to sensor networks, gives an amazing number of references, and, thus, is the perfect source for students, teachers, and researchers. Throughout the book the reader will find high quality text, figures, formulas, comparisons etc. - all you need for a sound basis to start sensor network research.""
