Abstract  

In MANETs, trust can be defined as to what extent a node can fulfil the expectations of another node. Packet loss detection and prevention is significant module of MANET security systems. In trust based method routing decisions are managed by an independent trust table. Traditional trust-based methods unsuccessful to detect the main underlying reasons of a malicious events. If MANET do not using fine-grained analysis method of packet drop in trust based method, the network may treat normal packet drop as malicious activity. It will misleads the MANET. Without fine-grained analysis the network may treat normal nodes as malicious and can disconnect from communication. It can degrade the network performance and malicious nodes remain undetected. We proposed a method which will improve the security in network by identifying the malicious nodes using improved fine grained packet analysis method. The method also improved the routing security using proposed algorithm. The system will improve the network performance and packet delivery ratio.
