Blackhole attacks (BHA) are one of MANET's most serious security issues. The malicious node destination node is performed from sending fake RREP towards source node that initiates route search & loses data traffic by the source node. Because of design flaws essential to routing protocols (RPs) into MANETs, several researchers have adopted various methods towards suggesting several kinds of defense mechanisms via the black hole problem. BHA is one of the most widespread active attacks that reduce network performance and reliability as a result of dropping packets coming through a malicious node. The purpose of black-hole node (BHN) is to trick every node of NW that wants to communicate with another node into thinking there is always a better route to destination node. AODV NW has a non-reactive RP to detect & deactivate BHNs. In this research, we have improved AODV by incorporating a new lighting technology that relies on trusted multiple RREPs to prevent BHA. The proposed technique is applied with NS-2.35 simulation tool. Results of proposed technique in positions of throughput, Routing above & Packet Delivery Ratio are so close towards original AODV deprived of a black hole.
