Title: Utilizing Behaviour History to
Fight Malicious Nodes in Wireless Ad-Hoc Networks
Abstract: Wireless
Ad-hoc networks are formed by wireless devices that facilitate
communication through cooperation amongst themselves; they overcome the
need for a central infrastructure. In our previous works, the effects
of the presence of malicious nodes on the performance of Ad-hoc
networks have been reported. Based on the
results of those works, here an approach that utilizes the behaviour
history
of the network nodes is proposed. In this approach, the main aim is to
identify
a route from source to destination that is free of malicious nodes.
Several
simulation studies were conducted to investigate the effect of the
proposed
behaviour approach on the performance of wireless Ad-hoc networks.
Results
that are carried out using OPtimised NETwork (OPNET) simulator show
that
the overall performance of the Ad-hoc networks, even in the presence of
malicious
nodes, can be significantly improved by incorporating the proposed
approach.
