In mobile ad-hoc networks are easily affected by Distributed Denial of Service (DDoS) intruder. Intrusion detection systems identify intrusions through continues monitoring of the network for unusual activity. Intrusion detection can be used to prevent or minimize the damage to the network and achieve possible recovery. In this proposed study, we will identify the intruder while the packet flow from the source to destination using the AIHAODV (Advanced Intrusion Handling Ad-hoc On-demand Distance Vector) protocol with the strategy of divide and conquer.
