Abstract
A mobile ad-hoc network (MANET) may include a plurality of nodes for transmitting data therebetween using a media access layer (MAC), where each of the nodes has a respective MAC address associated therewith. The MANET may also include a policing node for detecting intrusions into the MANET by monitoring transmissions among the plurality of nodes to detect frame check sequence (FCS) errors from a MAC address, and generating an intrusion alert based upon detecting a number of FCS errors for the MAC address exceeding a threshold. The policing node may also detect intrusions based upon one or more of failed MAC address authentications, illegal network allocation vector (NAV) values, and unexpected contention or contention-free operation.
