Analysis of energy efficiency of cooperative communication in Wireless Sensor Networks Liming Jin JiangXi YuZhou Vocational College of Science & Technology, Xinyu, Jiangxi, 338000 Keywords: wireless sensor networks; communication technology; efficiency analysis Abstract: Wireless sensor network (WSNs) is composed of a large number of cheap micro sensor nodes with wireless communication and computing capabilities, which will deploy in unattended monitoring area through the cooperation of autonomous monitoring tasks assigned, and sending the information of monitoring object collection to intelligent monitoring network system for remote users.
Marching, armed distribution and military material will supply situation, therefore the need to build a wireless sensor network to collect these information, And by the sink node transmitting the collected data to the command, the final fusion from the battlefield data form a perfect theater situation map.

The overflow of gypsum slurry cyclone were observed and tested, resulted show that: the main properties of the overflow slurry for: small density, light weight, its color and the main components and the absorber slurry layer better liquidity matter was basically the same; cyclone underflow slurry density high, high solid content, its color and the main composition and absorption tower bottom mobility was poor material was basically the same; absorption tower slurry, gypsum, gypsum slurry cyclone overflow the color shown in Figure 1 to 3.
