| dc.description.abstract | Mobile Ad Hoc Networks (MANETs) are important because they are widely used in war
zones, rescue missions and other civilian applications where it is almost impossible to use
any other networks. MANETs are temporary networks where nodes are allowed to join or
leave the network at any point in ~ime. Though MANETs offer flexibility, self maintenance
and dynamic topology, they suffer from limited resources, have less computational power
and are susceptible to attacks. Due to the dynamic nature of MANETs, the secure
transmission of data is one of the key issues in MANETs. Thus there is a need to safeguard
the network from internal as well as external security threats.
In this paper, I attempt to improve the security environment of one of the most popular
routing protocols in MANETs, the Ad Hoc On Demand Distance Vector Routing Protocol
(AODV). AODV is a reactive protocol which guarantees loop free routes during the
transmission of data, and the focus of this paper is mainly to secure the AODV protocol
against black hole attacks. This paper proposes the Forward Reaching Black Hole
Detection algorithm (FRBD) to detect single black holes in MANETs that are based on the
AODV routing protocol. This paper presents a solution that includes slight modifications in
the functioning of the AODV protocol. I demonstrate the proposed solution on a specially
developed Java based simulation tool. The paper examines the black hole detection
capabilities of the FRBD algorithm by applying it on randomly generated problem
instances. These instances vary based on the total number of nodes, paths and the location of the black hole node. Our analysis shows that the FRBD algorithm effectively detects
single black holes in the network and thus improves the overall security of MANETs. | en_US |
