Informationen zum Autor Timo D. Hämäläinen is Professor and Institute Vice President at Tampere University of Technology, Finland. Timo acted as a senior research scientist and project manager at TUT from 1997-2001. In 2001 he was nominated full professor at TUT/Institute of Digital and Computer Systems. He heads the DACI research group that focuses on three main lines: wireless local area networking and wireless sensor networks, high-performance DSP/HW based video encoding, and interconnection networks with design flow tools for heterogeneous SoC platforms. He has published over 30 refereed international journals and over 150 conference publications. Marko Hännikäinen is Senior Research Scientist and Mauri Kuorilehto, Mikko Kohvakka, Jukka Suhonen, Panu Hämäläinen are all Research Scientists at Tampere University of Technology, Finland. Klappentext Finally a book on Wireless Sensor Networks that covers real world applications and contains practical advice!Kuorilehto et al. have written the first practical guide to wireless sensor networks. The authors draw on their experience in the development and field-testing of autonomous wireless sensor networks (WSNs) to offer a comprehensive reference on fundamentals, practical matters, limitations and solutions of this fast moving research area.Ultra Low Energy Wireless Sensor Networks in Practice:* Explains the essential problems and issues in real wireless sensor networks, and analyzes the most promising solutions.* Provides a comprehensive guide to applications, functionality, protocols, and algorithms for WSNs.* Offers practical experiences from new applications and their field-testing, including several deployed networks.* Includes simulations and physical measurements for energy consumption, bit rate, latency, memory, and lifetime.* Covers embedded resource-limited operating systems, middleware and application software.Ultra Low Energy Wireless Sensor Networks in Practice will prove essential reading for Research Scientists, advanced students in Networking, Electrical Engineering and Computer Science as well as Product Managers and Design Engineers. Zusammenfassung This text is the first comprehensive practical guide to wireless sensor networks. The authors draw on their experience in the development and field-testing of autonomous wireless sensor networks to offer a guide to fundamentals, practical matters, limitations and solutions.
