Summary: | The Mobile Ad hoc Network (MANET) is an infrastructureless network that has
applications in many fields. MANETs can change locations and configure themselves
on the fly; the nodes are self-configuring and able to self-organize. For data
communication, nodes in the MANETs act as router to forward data packet to other
nodes in the network. To communicate in the network, the nodes need routing protocol
to establish a route and exchange the data in a secure way. Ad hoc On Demand
Distance Vector (AODV) is one of the frequently used routing protocols due to its
reactive nature advantage. Nevertheless, AODV has the disadvantage of being
attacked by various types of attacks, specifically black hole attacks and Distributed
Denial of Service (DDoS) attacks where it publicizes itself by announcing that it has
the shortest path to the destination by altering the important routing parameters. These
threats are difficult to handle because of their characteristics, like the huge scale of
botnets and the dynamic nature of attacking, which constitutes a DDoS attack. DDoS
attacks should be handled and mitigated directly from the network as early as possible.
Many researchers have come up with a number of research work for defending against
these attacks. However, most of these solutions lead to the increase in routing
overhead which affects the overall performance of the network. The main challenge
in MANETs is to come up with a secure routing protocol that is lightweight and whose
implementation results in less overhead, better performance and a secure network. For
that reason, a lightweight defense mechanism that can secure the network from the
attackers is resourceful as the cooperation between the neighbouring nodes is counted
in MANETs. This research focuses mainly on a defense against the Black Hole and
DDoS attacks which involves two authentication levels: a) layer-2 authentication, and
b) symmetric encryption on the control packets to secure the established path from
AODV routing before exchanging the data. This is done by modifying the
conventional AODV routing protocol. The primary focus of this approach is the sub layer that is layer 2 of the Open Systems Interconnections model (OSI), which uses
the Media Access Control (MAC) authentication for checking the validation and
authenticity of the nodes that want to participate in the network. Both routing
information and the MAC information are specifically checked for securing the
network. The solution is implemented in the AODV protocol and tested on various
scenarios in order to achieve the optimum results. The trace file which is the output
from the Network Simulator 2 (NS2) shows better improvement over existing
approaches. The analysis shows good network performance with maximum average
throughput of 96.5% and reduced routing overhead of 4.71%, offering true positive
detection rate at maximum value of 92%. Moreover, this proposed solution
endeavours higher packet delivery ratio with relatively less end to end delay (EED)
when compared to two recent research works (LSAM and HMAC). |
