Mobile ad hoc network routing protocols are highly susceptible to subversion. Previous research in securing these protocols has typically used techniques based on encryption and redundant transmission. These techniques prevent a range of attacks against routing protocols but are expensive to deploy on energy-constrained wireless devices. Experience in securing wired networks has demonstrated that, in addition to intrusion prevention techniques, it is useful to deploy intrusion detection techniques as a second line of defense. This paper discusses some of the threats to wireless ad hoc networks, and, specifically, some attacks against the AODV routing protocol. The paper also presents a tool aimed at real-time detection of these attacks. The tool monitors network packets to detect local and distributed attacks within its radio range.
