تشخیص و پیشگیری از حمله Wormhole در شبکه حسگر بیسیم با استفاده از پروتکل AOMDV☆

Unique characteristics like limited bandwidth, limited battery power and dynamic topology makes Wireless sensor network (WSN) vulnerable to many kinds of attacks. Therefore interest in research of security in WSN has been increasing since last several years. Infrastructure less and self-governing nature of WSN is challenging issue in terms of security. Wormhole attack is one of the severe attack in wireless sensor network. In this paper, the techniques dealing with wormhole attack in WSN are surveyed and a method is proposed for detection and prevention of wormhole attack. AOMDV (Ad hoc On demand Multipath Distance Vector) routing protocol is incorporated into these method which is based on RTT (Round Trip Time) mechanism and other characteristics of wormhole attack. As compared to other solution shown in literature, proposed approach looks very promising. NS2 simulator is used to perform all simulation.
