The wireless technology provides the communication between the devices without needs of any physical medium. It provides mobility capability to the devices for access at any time and any where. The benefits of flexible routing, global connectivity and a highly adaptive potential make Mobile Ad-hoc NETworks (MANET) suitable for a wide range of applications in both military and commercial environments, such as battlefields, disaster relief operations, mobile device/personal networking, mobile information sharing and vehicular networks. However, maintaining security in wireless ad-hoc networks is quite challenging, a lot of applications are ad-hoc based and in some cases it is desired that communication be made secret.
