چکیده انگلیسی
This paper tackles the problems of localization and coverage in randomly deployed high density sensor networks. In particular, it presents a novel and integrated approach that performs at once localization and coverage. We introduce here an approach based on a single mobile beacon aware of its position. Sensor nodes receiving beacon packets will be able to locate themselves. On the other hand, We exploit the localization phase to construct sets of active nodes that ensure as much as possible the zone coverage. In our approach the mobile beacon follows a Hilbert curve. The results of experiments conducted using the discrete event simulator Omnet++, are discussed, they allow us to justify our approach and to compare it to existing ones.
