One of the most active study topics in the field of mobile ad hoc network (MANET) is secure routing. Due to the unique network features of absence of central authority, fast node mobility, frequent topology changes, insecure operating environment, and limited resource availability, developing a reliable security protocol for ad hoc routing is a difficult job. MANETs are well-suited for emergency circumstances such as natural catastrophes or military applications because to their minimal setup and rapid deployment. As a result, data transmission between two nodes should always be secure. A mobile ad hoc network (MANET) black-hole attack is an offense that occurs when hostile nodes attract data packets by falsely advertising a new path to the target. A clustering direction in the AODV routing protocol has been proposed for the identification and mitigation of black-hole attacks in MANET. Every member of the unit will send a single ping to the cluster head in order to determine the unique difference between the quantities of data packets received and sent by each node. If the problem is detected; all nodes in the network will hide the infectious nodes. The system's performance was measured in terms of packet delivery ratio (PDR), end-to-end delay (ETD), and throughput. The ns2 simulator is used to record energy simulation conclusions.
