One Compressive Sensing Algorithm Based on Local Data in WSN

ZHAO Shu-feng1,HUANG Liu-sheng2(1.Department of Information Technology,FYZY,Fuyang 236031,China; 2.Department of Computer Science and Technology,USTC,Hefei 230026,China)  
Currently,one of the most outstanding issues in Wireless Sensor Networks(WSN) is energy saving.The existing data transmission in WSN not only wastes lots of energy,but also makes the energy consumption of the whole network unbalanced.Based on the data transmission characteristics of WSN,an improved compressive censing(CS) algorithm is introduced here to WSN.Duing the process,the CS algorithm dramatically reduces the data transmission times and ensures the same transmission times for each sensor node in WSN.The CS algorithm reduces the energy consumption for each sensor node and keep the WSN's energy and more balanced.
