Dedicated Trustee Detector of Black Holes in Manets

Abstract

MANET is developing the next generation wireless universe. However MANETS prove their performance only when routing is efficient. In this paper we propose a model of Dedicated Trust System (DTS) which aims in detecting the misbehaving nodes. We implement our DTD using zone routing protocol with trusted systems. We finally develop a reputation model with two new parameters trustee and bucy trustee, which aims in identifying the black holes and isolating them and show significant upgradation in the overall protocol performance. We make a comparative study of our defensive network with the zone routing protocol defenseless network. All simulations have been implemented using NS2 simulator.
