Energy Consumption at Nodes Wireless Sensor Networks Based on ZigBee

LI Shuai,LIU Hongli,LIU Shugang College of Electrical and Information,Hunan University,Changsha 410082,China  
This paper studies the key issues of how to reduce the energy consumption of the ZigBee nodes,through optimizing node's dormancy mechanism without affecting the quality of network communication.Low-power module chips are used in the hardware module and the selected chips are in multi-mode and can switch conveniently.The energy consumption of wireless communication modules to send and receive data is important.Based on this platform,the effect of the network nodes' sleeping time on communication quality and energy consumption is analyzed.The simulation shows that the power consumption can be reduced as much as possible without affecting the quality of network communication when node's sleeping time is around 20 ms.
