Mobile Ad Hoc Networks (MANETs) offer a dynamic environment where data exchange and routing between nodes occur without the help of any centralized server or human intervention, providing that nodes cooperate with each other. In such environment, the presence of malevolent nodes may result in wormhole attacks. In this paper, a secured AODV-based routing scheme (referred to as Timed and Secured Monitoring Implementation - (TSMI)) is proposed for mitigating such attacks. Simulation results are provided to demonstrate the effectiveness of our approach, using the packet delivery ratio, the number of broken links detected, and the number of packets received by destination, as performance indicators.
