IntroductionTraditional - detect the environment by randomly
deploying immobile sensors within the area.Mobile - each MS moves and operates according to its
current location. (wireless localization system)SensorGroup (SG) - GPS receivers are organized into
groups. (it is not cost-effective)Anchor nodes - at least three anchors. (size is enlarged)Centralized Mobile SensorGroup (CSG) - mobile anchor
with GPS receiver

Centralized SensorGroup NetworkFall Out Problem: To provide M node sufficient
information to execute the moving back, RPGMbroadcast should include the location of the moving destination of C node Lc_next in every RPGM round except Lc.
