Study of Hybrid Localization Noncooperative Scheme in Wireless Sensor Network

Algorithm 2

WCL with four anchor nodes.

Procedure Anchor()

    Repeat

     Move to a new position for each to 5

     transmission a packet including its ID, coordinate at the time;

        Until finish

End procedure

procedure  SourceNode()

   repeat

 Receive information from Anchor ();

 Calculate according to (3);

   until finish

Sort the anchor information at time;

for all the information IN at the same time

 if or

    Estimate position according to (5);

 else

    Discard IN;

end for

Use average of all estimated positions as the final value;

end procedure
