摘要：ABSTRACT : In this Paper a In wireless networks, security has become the prime factor of concern. The mobility of the nodes, in these so called Mobile Ad hoc Networks (MANETS), furthermore leads to a situation where it is very difficult to establish secure data transmission. Since the use of mobile equipments such as cellular phones or laptops is tremendously increasing and because of limited physical security, vulnerability to attacks, including an attack known as the wormhole attack, has become a challenging work. The wormhole attack is very powerful and preventing the attack has proven to be very difficult [3]. A strategic placement of the wormhole can result in a significant breakdown in communication across a wireless network. This addresses the aforementioned gap by providing a proper definition and categorization of wormhole attacks against MANET by introducing a new cooperative, clock synchronized technique based on Reference Broadcast System (RBS), and discussits effect on network performance. To improve network scalability and throughput, we propose the concept of thread for each and every node of MANET. So that our proposed scheme has three mechanisms namely, AODV (Ad hoc on demand distance vector protocol) for routing, Principle of RBS for threshold setting and ACK, for reliability of communication, are combined to detect and isolate wormhole attacks in ad hoc networks. That manages how the nodes are going to behave and which to route the packets insecured way.
