Signal strength as support to mobility detection on failure detectors

A Failure Detector (FD) is an essential building block to develop reliable applications on Mobile Ad-hoc NETworks (MANETs). To detect faulty nodes correctly the node mobility and disconnections are challenges that must be circumvented by an FD. This paper presents an FD algorithm that detects faulty nodes efficiently in MANETs. This approach explores the signal power intensity on the receiving messages to detect node mobility and improve the failure detector knowledge. The experimental results have shown improvements in the Quality of Service (QoS) when compared with other similar FDs.
