Abstract
The increase of the technology revolution is encouraging MANET (A Mobile ad-hoc network) to be used in different sectors and for different purposes. MANET can be used in a variety of different ways such as for personal usage, meetings, and recovery and relief from disasters. The demand on this type of network raises security concerns especially in reference to its specific features such as dynamic topology and no central administration point. A MANET is not a conflict-free environment, so many attacks are aimed at it, but the focus of this study is a DoS (Denial of Service) attack. This paper presents a novel method of MrDR (Monitoring, Detection, and Rehabilitation) to detect DoS attacks and it is applied in this experiment specifically on single MANET. The MrDR method is based on a trust concept, which it is assumed is not transitive. In addition, the trust value in the proposed method is something temporal, a short-lived action, and needs to be recalculated due to the dynamic infrastructure of MANETs. The simulation results of using the MrDR method prove that the effectiveness of the use of this method can increase network performance considerably.
