Evaluating Strategy with Grey Theory Utilized in Wireless Sensor Networks

This paper designs evaluation method based on the grey theory which aims at evaluate the usage of Wireless Sensor Networks in rail traffic. With the features of the facts that: The requested data sizes for assessment via grey theory method are not big, distribution rules of the data samples are not obliged ,and the evaluation workload is small , we use grey theory to verify each index mark in current evaluation system. Hereafter, the detailed assessment example is taken out to prove that the index mark getting from this method has practical significance and performs efficiently.
