In this article, the SAR (Security-Aware Routing) technology is applied in the AODV (Ad Hoc On-demand Distance Vector) routing protocol, the AODV is modified as viewed from security performances, the wireless Ad Hoc routing protocol with secure consciousness could be realized, and the secure routing protocol (SAR-AODV) is simulated in the OMNet++ simulation environment based on the platform of Windows 2003.

When the middle node receives these RREQ packages with special security attribute or trust level, it will first check whether it has the security level indicated in the RREQ package or the demanded authority or trust level, and if this node could not provide the demanded security level, it will discard the RREQ package, and will not transmit it outside, and if it has the demanded security attribute, it will transmit the RREQ package like common AODV protocol until the destination node is found. After the final destination node is found, the destination node will transmit a RREP package which will arrive at the source node according to the reverse route, and in this way, the route according with the secure standard will be established.
