A hybrid method to detecting failures in mobile sensor networks using localization algorithms

This paper presents a new approach to detect node failures to support fault tolerant application on mobile sensor networks in an optimized way. Our approach takes advantage of localization algorithm message exchanges to implement a failure detector algorithm, optimizing sent messages, reducing energy consumption and contributing to avoid the nodes scalability problem. We analyze a network performance for the Friedman Failure Detector, Monte Carlo Localization and both working together. The experimental results from simulations show an approximately reduction of 43% in the number of messages sent and are reported in this paper.
