Information fusion in Wireless Sensor Network based on rough set

To reduce the energy consumption and extend the network´s survival time is the key research problem in the Wireless Sensor Network. Much research work has been done on the placement of nodes and routing protocol, eliminating data redundancy by density controlling and hierarchical clustering algorithm. In this paper, it is proposed that information fusion is an effective way to reduce the communication data, save the energy consumption and thereby extend the life of the network. With the specific analysis an information fusion algorithm based on rough set is designed.
