Overview

Purpose - The purpose of this paper is to describe an adaptive approach for diagnosing faulty nodes in a wireless mobile environment.Design methodology approach - Based on a diagnosis approach that has been previously developed for wired networks. A discussion of the novel diagnosis protocol and its correctness is also included.Findings - In this paper, the author presents a new implementation of a failure detection service for wireless ad hoc and sensor systems that is based on an adaptation of a gossip-style failure detection protocol and the heartbeat failure detector. The authors show that the failure detector is eventually perfect - that is, there is a time after which every faulty mobile is permanently suspected by every fault-free host, and no host will be suspected before it crashes.Research limitations implications - The main limitations of this work is the lack of simulations results. Future works will be directed at providing such performance evaluations.Practical implications - The work introduced in this paper aims mainly at identifying faulty nodes in a wireless mobile environment. This service has been identified as one of the basic building blocks for dependable mobile ad hoc networks (MANETs).Originality value - The paper is first work that adapts a previously developed failure detection service to wireless and MANETs.
