Analytical Model and Performance Evaluation for the TRIDNT protocol
In Mobile ad-hoc networks, nodes must cooperate to achieve the
routing functions. Node misbehavior due to selfish or malicious
intention could significantly degrade the performance of
MANET because most existing routing protocols in MANET are
aiming at finding the most efficient path. A Two node-disjoint
Routes scheme for Isolating Dropper Node (TRIDNT) protocol. The protocol uses an incentive mechanism for selfish node to declare its selfishness behavior and also use two node-disjoint routes to reduce the malicious searching time.
In this paper, we give an analytical model and performance
evaluation for the TRIDNT protocol. First we calculate the time
taken to detect the malicious node in the routing path. Second we
will drive an expression for the expected attempt time until
finding a misbehaving free route, and calculate the probability of
failing in finding a misbehaving-free route in case of limited
number of attempts. Finally, the connection request blocking
probability and per flow throughput are calculated.
