Research Situation on Key Technologies of Data Gathering in Wireless Sensor Networks

The wireless sensor network is a kind of network that use data as its center.It has some characteristic such as the limitation of the hardware resource,self-organization network structure and the variability of network.So there are some difference between the wireless sensor network and traditional wireless network.And that decided the data gathering is the major research subject of the wireless sensor network.This paper introduced the structure and the function of data gathering system in the wireless sensor network,summarized the key problem and the key technologies of the data gathering in the wireless sensor network,analyzed and summarized the research situation of some key technologies such as routing protocol,security mechanism,data compression and data fusion,and the paper also look into the future of the data gathering technology in the wireless sensor network.
