A mobile ad-hoc network (MANET) (60) may include a plurality of nodes (61, 62) for transmitting data therebetween and a policing node (63). The policing node (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 more of integrity check values which do not correspond with respective data packets, usage of non-consecutive media access control (MAC) sequence numbers by a node, and collisions of packet types and/or MAC addresses.

La présente invention concerne un réseau mobile adapté (MANET) qui peut comprendre une pluralité de noeuds permettant de transmettre des données entre eux et un noeud de police. Ce noeud de police peut détecter des intrusions dans le réseau MANET par la surveillance des transmissions parmi la pluralité de noeuds afin de détecter des transmissions effectuées pendant une période non autorisée et de générer une alerte d'intrusion fondée sur cette détection. Le noeud de police peut aussi détecter des intrusions fondées sur une ou plusieurs valeurs de vérification d'intégrité qui ne correspondent pas à des paquets de données respectifs, sur une utilisation par un noeud de numéros de séquence Média Acces Control (MAC) non consécutifs et sur des collisions de types de paquets et/ou d'adresses MAC.
