There are two reasons for packet loss in multi-hop wireless ad-hoc network. Link error and malicious packet dropping are two different reasons. While discovering continuous packet loss in the network, it is difficult to identify whether the loss is because of link error or malicious drop. We are going focusing on insider attack case i.e. malicious packet dropping where malicious nodes that are part of the route that will drop a small amount of packet which will affect the network performance. The packet dropping rate in this case which is based on traditional algorithm is comparable to the channel error rate and it does not achieve the satisfactory detection accuracy. The correlation between lost packets is identified by using the bitmap obtained from individual node, to improve the detection accuracy. To allow the detector to find the truthful information about packet loss, a homomorphic linear authenticator based on public auditing architecture is applied. The proposed technique is collusion proof and causes low communication and storage overheads at intermediate nodes and it is also privacy preserving. The auditor will collect the information reported by individual nodes and will determine the reason for packet loss by to determine correlation between packet loss. The malicious node is eliminated from route once it is identified.
