Class NodePositionTracker

java.lang.Object
  drcl.DrclObj
      drcl.comp.Component
          drcl.net.Module
              drcl.inet.mac.NodePositionTracker

All Implemented Interfaces:: java.lang.Cloneable, ObjectCloneable, ObjectDuplicable, java.io.Serializable

public class NodePositionTracker
extends Module

This component divides the X-Y plane of the simulated space area into multiple subareas. Each mobile node's MobiltiyModel periodically reports its position to NodePositionTracker. When a NodePositionTracker receives a neighboring node inquery from the Channel component, the NodePositionTracker first finds out which subarea that sender node is located and returns the nid's of all mobile nodes which are currently located in all neighbouring subareas.
