Security Enhancement for Wireless Network Communication

In wireless communication any node can join or leave network which causes lot of security limitations and various kinds of attack. One such attack is the vampire attack which is against the Optimized Link State Routing protocol (OLSR) known as the node loop attack occurs when topological knowledge of the network is exploited by an attacker who is able to make the loop with the victim from the rest of the network and subsequently deny communication services to the victim. The solution to defend the OLSR protocol from node loop attack is done by Denial Contradictions with Fictitious Node Mechanism (DCFM) and the threshold ECDSA authentication is used for high security. This paper provides 1) high security to the message sent in the wireless network, and 2) the proposed system detects vampire attack and recovers the network from the attack.
