TRUTHFUL DETECTION AND PRESERVING THE PRIVACY OF PACKET LOOSING IN AD-HOC NETWORK

Computer Engineering

In multi-hop wireless ad-hoc network packet loss can be resulting from specifically due to one-of-a-kind motives. Link errors and malicious packet loss are two causes for packet loss. While discovering continuous packet loss in the network, its miles difficult to find out whether the loss is due to link errors or by means of malicious packet loss. In this paper we can especially concentrate on insider assault case this is malicious packet losing wherein malicious nodes that are a part of the course so that it will loss a small quantity of packet so that it will have an effect on the network overall performance. Primarily based on conventional algorithm when we examine the packet losing rate and the link errors rate, the packet losing rate does no longer achieve the great detection accuracy. To improve the detection accuracy, the correlation among lost packets is recognized via using the bitmap obtained from individual node. In this paper a homomorphic linear authenticator that's based on public auditing structure is carried out, which permits the detector to discover the straight forward records about packet loss. The proposed method is privacy maintaining, collusion proof and causes low communication and storage overheads at intermediate nodes. The auditor will accumulate the statistics stated by using character nodes and will decide the motive for packet loss by using determining correlation between packet loss. Once the malicious node is recognized then it is eliminated from network.
