Storage Of Distributed Data Management In Wireless Sensor Networks

Wireless sensor network(WSN) is composed of multiple sensor nodes. With the development of network technology, technology of wireless sensor network has greatly improved. It makes wireless sensor network be applied to all kinds of industries. Such as military and civilian etc. The data that sensor network produced has played an important role in people’s daily life. The purpose of wireless sensor network is to collect data to reach the user’s interest.The data is the core of this network, sensor nodes collect data and deal with the data.And send data to the users at the end. But compared with the traditional wireless networks, as the sensor node’s energy is limited, and it’s working environment is special,the energy of wireless sensor networks will be quickly expended.With the sensor nodes collecting data, sending mass of data, their communication will also make the energy in themselves wasted. The nodes will damage if there’s no energy. So the life of the network will be effected. So how to save the energy, and make the life of the network be prolong.Researchers show that distribute data storage can reduce energy consumption in order to decrease the life of the WSN.1)Under the rules of node selection, choose which node to store the data.2)Use data fusion for the data that WSN generated to reduce the data volume.3)To study the mobile strategy for Sink, and prove it.4)Make Shamir secret sharing after data fusion to improve the security of network storage.
