A Novel Approach to Enhance AODV Security in Case of Multicast
It is well-known that security today has become a primary concern in order to provide secure communication between mobile nodes. It is very important to protect the network from hackers. For most existing routing protocols of Mobile Ad hoc NETwork (MANET) efficient security mechanisms against the attacks from malicious & selfish nodes are highly required. In existing AODV, though there exist the security provision against a well known "Black Hole" attack but the threat is still there so there is a need to enhance the security. Black hole nodes are malicious nodes that agree to forward packet to destination but do not forward packet intentionally.
