摘要
针对无线传感器网络的技术特点,一项新的技术标准在2002年被提出并不断被更新和完善,获得了广泛的支持,这就是ZigBee技术。ZigBee作为一种新兴的近距离、低复杂度、低功耗、低数据速率、低成本的无线网络技术,主要用于近距离无线连接。它有自己的协议标准,在数千个微小的传感器之间相互协调实现通信。这些传感器只需很少的能量,以接力的方式通过无线电波将数据从一个传感器传到另一个传感器,所以它们的通信效率非常高。
In view of the technical characteristics of wireless sensor networks, a new technical standard in 2002 was proposed and has obtained the widespread support eonsfant after updating and improving. It is the ZigBee technology. ZigBee, as one kind of emerging wireless network technology with near distance, low complexity, the low power loss, the low data rate, the low cost, is mainly used in the near distance wireless connection. It has its own agreement standard to communicate belween several thousand small sensors intercuordination realization correspondence. These sensors only need very few energies, pass the data by the relay way through the radio wave from a sensor to another, therefore thev communicate with an extremelv high efficiency.
