Q. Explain about Security aware protocols?

The security-Aware ad hoc Routing (SAR) protocol based on the security attributes integrated into the ad hoc route discovery provides sufficient security on WSN affirms that SAR overcomes apparent weaknesses in traditional methods of determining distances between nodes based on hops by providing new routing measurements based on geographic location and other attributes enables secure implementation based on the forwarding behavior of broadcast packets. The distance between WSN nodes might not be the shortest, and the most secure, based on a quantifiable secure route. Based on the SAR protocol, the nodes in the network are mirrored into a hierarchy based on explicit partial-ordering of privilege levels.

In QoP, Each node is assigned trust levels which cannot be arbitrarily changed. The interception, modification, or subversion of messages on transmission is protected by the triple key management mechanism integrated into the security solutions. The security of the packets on transmission based on the (Security-aware AODV) protocol requires the addition of the RQ SEC REQUIREMENT to discover a packet en-route. Nodes that receive the RREQ packet assess the integrity and security compliance status and the protocol forwards the packet if it is deemed secure. Packets that fall short of the security requirement are dropped.
