An Implementation of Black hole Attack Detection in MANET Using Trusted Proxy Node (TPN) with AODV

This Research proposes Trusted Proxy Node (TPN) method which is responsible for the trust calculation. The TPN measures an best possible route for communication by examining the network parameters like delivery ratio, overhead & delays. After this trust value index is calculated and TPN node issues a certificate to every node in its network range. This work is presented to detect black hole nodes for AODV protocol in MANET. To make a contribution in routing the nodes must have two trust index (TI) certificates & can be believe as a suggested node by TPN. The record of this certificate is keep up in Trust Index (TI) Table. This trust index table is shared with the data aggregation server with help of trusted nodes. Improved AODV protocol using C++ is written, to simulate the Black Hole attack. In order to test this method simulation model was developed. The simulation results show the usefulness of our scheme compared with usual scheme.
