Using Directional Antenna for Continuous Moving Object Tracking in WSN with Uncovered Holes

摘要: As a distinguished target monitoring system, wire- less sensor networks have spawned great advances. Most existing work concentrates on improving the accuracy and energy saving in fully covered area by making full use of omnidirectional antenna. In reality, however, due to death sensors caused harsh environment or depletion, may enter into hole that is not sensors. On other hand, representative researches boundary detection do take tracking consideration. To address this issue, we introduce idea applying directional antenna accomplish mobile WSN with uncovered holes. We propose collaborative signaling protocol achieve goal continuous low-energy-consumption. Simulation results shown proposed approach can realize real- time moving object when it runs out hole, at same time, consume much than based methods.
