TRIUMF-Trust Based Routing Protocol with controlled degree of Selfishness for Securing MANET against Packet Dropping Attack
In a mobile ad-hoc network, nodes cannot rely on any fixed
infrastructure for routing purposes. Rather, they have to
cooperate to achieve this objective. However, performing
network functions consumes energy and other resources.
Therefore, some network nodes may decide against
cooperating with others; selfish nodes. Also security issues are
more paramount in such networks even more so than in wired
networks. In particular these networks are extremely under
threat to insider; malicious nodes; especially through packet
dropping attacks. Selfish and malicious nodes are termed as
misbehaving nodes. Giving the selfish nodes the incentive to
cooperate, while isolating the malicious nodes have been an
active research area recently.
In this paper, we design a novel secure reactive routing
protocol for Mobile ad hoc networks (MANETs), called
TRIUMF (Trust-Based Routing Protocol with controlled
degree of Selfishness for Securing MANET against Packet
Dropping Attack).
