Detecting Malicious Nodes for Secure Route Discovery in MANETs

In Today's world secure transmission of data is ubiquitous need. In MANET secure route discovery and secure routing of data plays an important role in data transmission. Because of it's dynamic topology, infrastructure less and openness, lots of intruders or malicious nodes getting a big opportunity to insert themselves as one of the legitimate nodes in the network. By taking this advantage they break down network performance of their malicious behavior. The major challenge is to secure route instead of data. Actually there is no fun to protect data rather than to protect route if route containing malicious nodes and packet is dropped by any of intermediate nodes due to one or another reason. In our paper we detect malicious nodes are restricted from router selection in the future by other nodes in network for secure data transmission.
