In recent days network is suffering serious problems with the packet loss. Dropping of received packets, even it has adequate buffers is very common in Disruption Tolerant Network. The DTN node facilitates communication between mobile nodes. Sometimes the mobile node selects the DTN with lowest reputation that affects packet delivery ratio. If there is a malicious node in the route, the data packet does not reach its destination. Repeatedly the misbehaving nodes may forge some records to avoid being spotted. To solve these issues we propose a scheme to limit the packet rolling in the direction of misbehaving node. The contact record preserves the previous performance of DTN and the mobile nodes select the best rated DTN for its communication. The record handler is maintained to keep track of incoming and outgoing packets. The witness nodes identify the real misbehaving node. The malicious node needs to be identified and is barred. The genuine packet loss, malicious packet loss are differentiated.
