AODV-SEC is an improved version of SAODV protocol. It is a protocol which is based on the AODV extension mechanism described. In this scenario a PKI is used as a trust anchor. Hence, it is necessary that every node in the network owns a certified keypair. In addition, every node needs to possess the current certificate of the Certificate Authority (CA) to be able to verify previously unknown certificates from other nodes. Therefore, the authors' approach for AODVSEC is to include the respective certificates into the route setup packets. In AODV-SEC smaller certificate type mCert is introduced, which is especially suitable for mobile scenarios using WLAN communication.
