The active operational environment of Mobile Ad hoc NETwork (MANET) makes it exposed to a variety of network attacks. Thus reducing the vulnerability is becoming a top priority. Wireless networks are susceptible to many attacks, including an attack known as the wormhole attack, has become a challenging work. The wormhole attack is very powerful and preventing this attack has proven to be very difficult. This paper addresses the aforementioned gap by introducing a new cooperative , relative approach, based on Reference Broadcast System (RBS). To improve network scalability and throughput, we propose the concept of the relative velocity between sender & the receiver node of the 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 wormhole attacks in ad hoc networks.

There are verities of broadband technologies (Priya et. al, 2014), such as cable, DSL, power line, satellite, and wireless. Each of these implementations can provide similar services to consumers and businesses. Generally broadband service delivery can be separated into two main categories: Wired and Wireless. Wired broadband delivers services over some type of wire connected around the area. Wireless broadband uses the electromagnetic spectrum and does not require a wire over the area.
