Abstract
Attackers could take advantage of the cooperative
nature of MANET’s routing protocols, by participating in the
route discovery procedure to include themselves in routes, then
simply drop data packets during the forwarding phase, aiming
at a DoS (Denial of Service) attack. In this paper we deal with
the detection and isolation of such malicious nodes. We first
propose a monitoring technique different from the promiscuous
overhearing (watchdog) used by almost all the current solutions,
that overcomes many watchdog’s shortcomes. After that we
propose a testimony-based isolation protocols basing on our
monitoring technique.
