- Abstract
- A mobile ad-hoc network (MANET) consists of independent mobile nodes which are connected by wireless links. The characteristics of ad hoc network like dynamic topology of the network induce various attacks which can spoil the whole network. Black-hole attack is one of the serious security threats to routing protocols such as DSR in MANET. Black-hole nodes exploit the sequence number or hop count of routing protocols to assert themselves to be the shortest path to the destination node, and then they eavesdrop or drop data packets that pass through. When a black-hole attack is in progress, the number and frequency of generated packets from the black-hole node are slightly different from other normal nodes. The proposed method which periodically exchange specific signal between moving intrusion detection node nodes is effective to detect distinct signs of black-hole attacks. Because the use of moving intrusion detection nodes increases computing complexity and energy consumption, it is required to find the acceptable number of moving intrusion detection nodes. In this paper, computer simulation using ns-2 network simulator deducts the adequate amount of moving intrusion detection nodes. And we have shown that the number of moving intrusion detection nodes of about 15% of the normal nodes is sufficient to get a satisfactory performance.
