VSMURF: A Novel Sliding Window Cleaning Algorithm for RFID Networks

Pseudocode 1

Adaptive sliding window cleaning algorithm.

Input: = set of all observed tag IDs

    = required completeness confidence

    = the maximum threshold of tag’s speed

    = the radius of reader’s detection range

    = the frequency of reader’s detection

Output: = set of all present tag IDs

Initialize:

While do

 For (  in  ) do

   if()

   Else

   End if

   If(tagExist())

     Output i

   End if

   If()

   Else if()

   Else if()

   Else

   End if

 End for

End while
