A mobile ad-hoc network (MANET) (60) may include a plurality of nodes (61, 6 2) for transmitting data therebetween and a policing node (63). The policing no de (63) may detect intrusions (64) into the MANET (60) by monitoring transmissions among the plurality of nodes (61, 62) to detect transmissions during an unauthorized period and generate an intrusion alert based thereon. The policing node (63) may also detect intrusions (64) based upon one or mor e of integrity check values which do not correspond with respective data packets, usage of non-consecutive media access control (MAC) sequence number s by a node, and collisions of packet types and/or MAC addresses.
