Reliable routing in Mobile Ad hoc NETwork (MANET) depends on
individual node cooperation. The entire network performance may
degrade because of even a single misbehaving node participating as an
intermediate node. Thus, there is a need for incorporating secure
routing with MANET to successfully operate in an adverse
environment where routing security threats are employed. Looking at
a few of the unsuccessful attempts by state-of-the-art routing schemes
at certain applications, this paper proposes a trust-based secure routing
termed as Enhanced Self-Detection Routing Scheme (ESDRS). This
proposed scheme incorporates a self-detection procedure into a
standard dynamic routing protocol Ad hoc On-Demand Distance
Vector (AODV), finally resulting in detection and reaction to malicious
nodes in MANET. The validation of the proposed approach is carried
out through a comparative performance analysis with the recent
Evolutionary Self-Cooperative Trust (ESCT) scheme and the standard
AODV. The comparison is based on computations of Packet Delivery
Ratio (PDR), delay, throughput, jitter, number of dropped data packets,
Probability of Detection (PoD) of malicious and benevolent behavior,
and normalized routing overhead while varying the number of nodes,
the number of attackers, and node speed. Simulation results affirm that
the proposed scheme improves the metric values as compared to the
other routing schemes.
