MARS: Misbehavior Detection in Ad Hoc Networks

To detect misbehavior on data and mitigate adverse effects, we propose and evaluate a MultipAth routing single path transmission (MARS) scheme. The MARS combines multipath routing, single path data transmission, and end-to-end feedback mechanism together to provide more comprehensive protection against misbehavior from individual or cooperating misbehaving nodes. The MARS scheme and its enhancement E- MARS are evaluated by means of simulation under various adverse scenarios. The simulation results show that the MARS and E-MARS schemes provide better network performance and considerable protection to data transmission than some DSR-based transmission systems at the expense of moderate overhead. Compared to the DSR-based schemes, the proposed schemes deliver up to 45% more data with 20% misbehaving nodes under individual misbehavior, and up to 28% more data with 40% misbehaving nodes under colluded misbehavior.
