Detection and Prevention of Black-Hole Attack in MANETS
Ameeta Seehra · 2014
Secure routing in the field of MANET is one of the most emerging areas of research. Designing a trustworthy security protocol for ad hoc routing is a challenging task due to the unique network characteristics such as, lack of central authority, rapid node mobility, frequent topology changes, insecure operational environment, and limited availability of resources. Due to minimal configuration and quick deployment, MANETs are suitable for emergency situations like Natural disasters or Military applications. Thus data transfer between two nodes must require security. 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. A clustering approach in AODV routing protocol for the detection and prevention of black-hole attack in MANETs has been proposed. 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. The analysis of the system performance has been done in terms of Packet Delivery Ratio (PDelR), Detection Rate (DR) and Throughput and simulation results are obtained using ns2 simulator.
