An Advanced Trust-Based Routing Protocol For Mobile Adhoc Network Under Black-Hole Attack

Mobile Adhoc Network (Manet) is a group of independent mobile nodes without fix topology and centralized administration. Because of absence of centralized administration, Manet is highly exposed to active as well as passive attacks. The existing routing protocols don't have security provision to protect the Manet against any type of attack. The Black hole attack is an active attack and effectively affects the performance of Manet by pretending itself as the safest and shortest path to the destination. So, there is a need of security provision in the routing protocol to protect the network against such attacks to avoid performance degradation. In this paper, An Advanced Trust-Based Routing Protocol (ATBRP) is proposed and implemented in NS2. The simulation results show that the proposed protocol defend the network from Black hole attacks and achieves better performance in terms of Packet Delivery Ratio (PDR), delay and throughput as compared to Dynamic Source Routing (DSR) protocol.
