Abstract

Target tracking systems using wireless sensor networks  have  been  used  in  many  application  domain such  as  battlefield  surveillance,  wildlife  monitoring  and border  security.  These  applications  need  to  meet  certain real-time constraints in response to transient events, such as  fast-moving  targets  or  real-time  property  should  be considered  as  the  most  important  requirement  of  the tracking  system.  In  this  paper,  we  develop  a  real-time target tracking system that utilizes the Lateration method (for  localization)  and  the  event-driven  routing  protocol EMRP  (for  reporting)  running  over  an  energy-efficient MAC protocol. The performance of collaborative tracking system  in  term  of  energy  consumption,  tracking  delay, and  trajectory  accuracy  is  evaluated  in  extensive computer  simulation.  The  results  show  that  our  method achieves  better  energy  consumption  while  maintaining  a reasonable  accuracy  of  tracking  performance  and achieving real-time requirement.
