Towards Improving Failure Detection in Mobile Ad Hoc Networks

Failure detection in distributed systems under MANET environment is a hard task to achieve. Indeed, due to mobility and resource constraints, traditional protocols record a high number of false suspicions. We propose in this paper a new failure detection protocol for MANETs that achieves a better compromise in terms of accuracy and completeness, by introducing new mechanisms to correct false suspicions. Simulation results are reported to compare the performances of our protocol with other approaches.
