Diminution of MANET Attacks by HOOSC Scheme

In this paper, an Ad-Hoc On Demand Distance Vector (AODV) protocol along with HOOSC scheme is put forward which encrypts the message to be sent and provides security for consistent routing. HOOSC algorithm allows a sender in the IBC (identity based cryptography) to send a message to a receiver in the PKI (public key infrastructure). Security in Mobile Ad-Hoc Network is an important concern for the proper functionality of network. During routing, MANET often suffers various security attacks because of the absence of clear defense algorithm. But the attacks, which can bring a large damage to MANET is called Black Hole and Grey Hole attacks. These attacks can distract the process of routing because of their direct attack on the router. Hence, several energy efficient routing algorithms and protocols are used in the previous works which are not capable efficiently to face these attacks. So HOOSC scheme is used which is very suitable to provide the security solution. In this work, the comparative analysis has been carried out by using AODV protocol without security, Message Digest algorithm and HOOSC Scheme along with AODV protocol. The simulated results show HOOSC gives better and enhanced results to mitigate the attacks in MANETs when it get modeled with HOOSC Scheme.
