IMPROVING THE ATTACK DETECTION ACCURACY USING HLA IN WIRELESS AD HOC NETWORK

In wireless ad hoc network packets are loosed due to two conditions one is due to the disturbance in the channel and another one is due to the intrusion (i.e.) intruder discard the packet. In this paper we focus on the inner attack (i.e.) the attack caused by the intruder who maliciously discards the packets. The malicious node pretends to be an one of the node in the routing path and cause the attack. Conventional algorithm does not provide the efficient detection of packet loss so, In order to improve the detection accurately we propose correlation function and also for the correct calculation of correlation we implement BLS based Homomorphism Linear Authenticator to check the information provided by the node are true. The HLA architecture provides privacy preserving, collusion proof and allows low communication and storage overheads.
