Application of Cognitive Radio in ZigBee Wireless Sensor Network
摘要
Abstract
The concept of Cognitive Radio is utilized in WSN based on ZigBee technology. A novel multi-spectrum and multi-hop Ad-hoc method is implemented. This new method brings solution to the problem of low utilization of spectrum in traditional network by making full use of the energy detecting function of modern RF chip. This method staticly allocates its communication channels only at the establishment period .An improved method is proposed, which has the intelligence to decide whether the nodes should switch their channels when RF environment has changed.关键词
