Approximate algorithm for median query based on WSN
An approximate algorithm for median query（AAMQ） based on WSN was proposed.In AAMQ,each node could estimate the value of the distinct number,and created a subsequence samples which get K percent of the most com-monly used values in its own observed values,and then broadcasted its subsequence to the p...
