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.
