Some features of Mobile Ad hoc Networks (MANETs), including dynamic membership, topology, and open wireless medium, introduce a variety of security risks. Malicious nodes can drop or modify packets that are received from other nodes. These malicious activities may seriously affect the availability of services in MANETs. Therefore, secure routing in MANETs has emerged as an important MANET research area. In this paper, we propose a scheme that enhances the security of Optimal Link State Routing version 2 (OLSRv2) in MANETs based on trust. In the proposed scheme, more accurate trust can be obtained by considering different types of packets and other important factors that may cause dropping packets in friendly nodes, such as buffer overflows and unreliable wireless connections. Simulation results are presented to demonstrate the effectiveness of the proposed scheme.
