Abstract: Malicious packet dropping and link error are the two main references for message dropping in all dual hop wireless adhocnetwork. Since the observation made on continuous packet losses that taking place in the network. Hence this paper is interested in determining various causes for message dropping and mainly focused on identifying whether it’s caused because of connectivity errors by the nodes only or even by the mixed force of destructive and connecting error of packet drop. The main interest is on inside attacker case, where the malicious nodes are even the part of any particular route that exploits their knowledge of the communication context that selectively drop a small packets at each node that critical the performance of the network. Since the packet dropping rate is compatible to the channel error rate, various conventional algorithms that are used in determining the packet loss don’t bring satisfactory determining accuracy. Hence to improve the detection accuracy, auto correlation functions are proposed in between the lost packets. The public based auditing function is implemented in the architecture known as Homomorphic Linear Authenticator (HLA) is done in the detector side to check for the truthfulness for the lost packets by any node that is involved in data transfer. Hence, it provides collusion proof, and also lowers the communication and storage overheads and privacy preserving. Finally, to reduce the computation overheads the block based packet mechanism is proposed.
