Key Node Oriented Black Hole Attack and Detection

Abstract

The key node oriented black hole attack means once the attack node is distributed near the key nodes in the network, it will do serious damage to the network performance. Thus, in this paper, based on implementing network key node recognition by computing the reputation value, propose the detection method of the key node oriented black hole attack. NS2 simulation results show that the key node oriented black hole attack on network have greater impact on packet loss rate and delay than the key node non-oriented attack, and compared the detection method of the key node non-oriented attack, the proposed detection method can be more efficient detection for the black hole attack to key nodes.
