The relative advantages of the various vertices may vary depending on the criterion used. The main objective of this end-of-studies project is to propose a fault-tolerant solution which consists in exploiting the local position indicators with the aim of guaranteeing the correct operation of the wireless sensor network even after the failure of some of its components.frGraph theory, local position indicators, wireless sensor networks, failures, fault tolerance, simulation.Thesis
