As microelectronic, sensor technology and telecommunication technology eveloped, wireless sensor networks go forward rapidly in recent years. Furthermore, some implementations for either civil use or military use are also put into practice. Because of those achievements, the development of wireless sensor networks has a bright future. The ZigBee chi dazzle technology is a standard wireless network protocol designed for low-speed wireless sensors. It can be competitive in the market and also popular in practice, especially for its low power consumption and low cost.This paper introduces the characteristic of ZigBee in detail. It emphasizes the advantage of low ralph lauren polo shirts consumption in low-speed wireless sensors, with comparing with the other popular wireless protocols. Because the definition of the physical layer in ZigBee is based on 802.15.4 Lacoste Polo Shirts criterion, the definition is definitive. However, the definitions in network layer are different among nike shox shoes companies. In addition, they brought forth the choice and support of routine in algorithm of their respective own. Therefore, this paper focuses on the routine algorithm in ZigBee.On one hand, saving cheap wedding dresses 2010 power is important in ZigBee networks. In ZigBee tree-structure, the nodes' in higher layer are responsible for managing sub-nodes and part of data routine.
