Objective: Finding the Packet dropping attacker and collecting the missing packet in the MANET is one of the challenging task since the characteristics of the MANET node mobility. Packet Transmission from the source node to the Destination node is done after sending the Route Request and Route Reply, reliable path chosen based on the protocol selection in Mobile Adhoc Network which is self-organized running without any basic infrastructure. Data which is going to send by the sender is divided in to the packet and put sequence numbering on the packet finally transmitted on the medium. Each and every packet get travelled on the assigned path to reach to the destination. If any packet missed on the transmission the source node has to retransmit to the destination. while forwarding the packet from one hop to another the packet dropper attacks are play dropping the packets.

Methods: There are several methods were proposed for elaborating the packet dropping attacks and solution for finding the attackers in the MANET, but none of the methods proposed for collecting the missed packet instead of getting retransmission. Divide and conquer method between the route to destination path applied to finding the packet dropper attacker and collecting the missing packet from the previous node.

Findings: The proposed method could be implement using network simulator and performance result could be better than existing packet dropper attacker work.

Novelty: This proposed article shows packet dropper attackers in the MANET and collecting the missing packet by using the divide and conquer algorithm in the source to destination path route.
