ZigBee and Bluetooth are the wireless communication technologies that play an important role in wireless ad-hoc networks.This paper analyzes and compares different low-power control strategies used by two kinds of technique standards, furthermore, we observe the current consumption, and then come to a reasonable conclusion through the tests of two kinds of typical applying circuit.ZigBee has a significant advantage on low-power consumption.While the Bluetooth 4.0 combines high-speed and low-power consumption, and to a large extent, it reduces the power consumption.In general, ZigBee technology and Bluetooth technology have their own advantages, as well as they complement for and compete with each other. A INTRODUCTIONZigBee and Bluetooth are both IEEE802.15 series,the WPAN ( Wireless Personal Area Networks)wireless communication standard specification.The main features of this series of standards is a short-range, low-power, low-cost, small-scale networking and communications equipment for personal operating space.ZigBee is a low rate wireless communication technology defined by the working group IEE802.15.4 to fit for cheap, low complexity portable or mobile devices,mainly suitable for automatic control, sensing, monitoring and remote control, etc. Bluetooth is defined by the IEEE802.15.1 for supporting a short-range radio technology communication devices,mainly used between the mobile phone, PDA, wireless headsets, laptops and other personal devices.In terms of low-power Bluetooth deficiency,Bluetooth SIG has also filed a Bluetooth version 4.0,namely,Bluetooth low energy.Now with the large-scale popularity of mobile Internet, ZigBee and Bluetooth technology is increasingly widely used in all aspects of life,the low power consumption has become a major consideration.In many application scenarios,it needs to consider the the lowest power consumption,so that equipment can run much longer.This paper analyzes the characteristics of ZigBee and Bluetooth from the view of international standards in low-power control strategy,then select the typical unit circuit to test.This paper has a good practical significance for the selection of two applications of wireless communication technologies. B INTERNATIONAL STANDARDS IN LOW POWER STRATEGY BETWEEN ZIGBEE AND BLUETOOTH B.A LOW POWER STRATEGY IN ZIGBEEZigBee technology includes the Media Access Control layer (MAC) and Physical Layer(PHY),at the beginning of its standards,it includes a variety of low-power control mechanisms.
