摘要

Ad hoc On-demand Distance Vector routing protocol is one of the most popular reactive protocol used for Mobile Ad hoc Network, is target of many denial-of-Service attack types. Whirlwind attacks uses a malicious node to make one routing-loop on the discovered route. All data packets are dropped due to they over time-life. This article proposes a mechanisms to manage and provide digital certificates (DC) for Mobile Ad hoc Network (MANET) without public key infrastructure. A digital certificates authentication mechanism secure that only ＂friendly＂ nodes to collaborate in the route discovery process, goal is to prevent malicious nodes that joined the discovered route, such as Whirlwind. A new routing protocol named AODVDC by integrating our solutions into AODV routing protocol. Using NS2, we evaluate the security performance using scenario where there are nodes move ramdomly and Whirlwind attacks, compared with related protocols. The simulation results showed that our approach has better performance in terms of packet delivery ratio, routing load and route discovery delay compared to related works under attack scenario.
