Malicious drops is one of the attack to drop the packets. It affects the transfer of data from source to destination and sends a fake acknowledgement as received. The acknowledgement that is forwarded will reach the source and wait for the response. Till the timeout it waits and start to transmit the packet again. Malicious nodes does not have any intension to drop the packets. We proposed a system to reduce malicious nodes prevailing in the transmission path. To avoid these malicious nodes we also propose on-demand routing protocol and digital signature acknowledgement. After the detection of the malicious nodes packet blocking is implemented and secure routing is done.
