tailieunhanh - Wireless sensor netWorks: ApplicAtion‐centric Design

Over the past decade, there has been a prolific increase in the research, development and commercialisation of Wireless Sensor Networks (WSNs) and their associated technologies (see Figure 1). This rise has been a result of a number of contributing factors, including continued miniaturisation (leading towards an era of truly ‘pervasive’ and ‘invisible’ computing); low-power circuits, devices and computation (for example, the ultra-low-power sleep states now found in microcontrollers); and efficient short-range communication (such as ZigBee and Bluetooth). The dramatic rise in WSN activity, fuelled by the prospect of a new computing paradigm, has resulted in the topic being researched (and taught) in the electronics and computer science departments. | WIRELESS SENSOR NETWORKS APPLICATION-CENTRIC DESIGN Edited by Dr. Geoff V Merret and Dr. Yen Kheng Tan Editor-in-Chief Wireless Sensor Networks Application-Centric Design Edited by Dr. Geoff V Merret and Dr. Yen Kheng Tan Editor-in-Chief Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2010 InTech All chapters are Open Access articles distributed under the Creative Commons Non Commercial Share Alike Attribution license which permits to copy distribute transmit and adapt the work in any medium so long as the original work is properly cited.
