Approximate algorithm for median query based on WSN

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...
