A Novel Approach for Preventing Black-Hole Attack in MANETs
نویسنده
چکیده
A black-hole attack in the Mobile Ad-hoc NETwork (MANET) is an attack occurs due to malicious nodes, which attracts the data packets by falsely advertising a fresh route to the destination. In this paper, we present a clustering approach in Ad-hoc On-demand Distance Vector (AODV) routing protocol for the detection and prevention of black-hole attack in MANETs. In this approach every member of the cluster will ping once to the cluster head, to detect the peculiar difference between the number of data packets received and forwarded by the node. If anomalousness is perceived, all the nodes will obscure the malicious nodes from the network.

Secure Routing Protocol: Affection on MANETs Performance
In mobile ad hoc networks, the absence ofinfrastructure and the consequent absence of authorizationfacilities impede the usual practice of establishing a practicalcriterion to distinguishing nodes as trusted and distrusted.Since all nodes in the MANETs would be used as router inmulti-hop applications, secure routing protocols have vital rulein the security of the network. So evaluating the perf...

Mobile ad-hoc networks (MANETs) are autonomous,infrastructure less, self-organized networks. In MANETs, nodes are not stationary and thus move arbitrarily, resulting in rapid and unpredictable topology changes in the network. Due to the limited transmission range of the nodes in the MANETs, these nodes are not capable of directly communicating with each other. Hence, routing paths in MANETs pot...

Wireless networks are gaining popularity to its peak today, as the users want wireless connectivity irrespective of their geographic position. There is an increasing threat of attacks on the Mobile Ad-hoc Networks (MANETs). Black hole attack is one of the security threat in which the traffic is redirected to such a node that actually does not exist in the network. It’s an analogy to the black h...
