An ad-hoc network is often defined as an infrastructure less network, meaning a network without the usual routing infrastructure like fixed routers and routing backbones. Typically, the ad-hoc nodes are mobile and the underlying communication medium is wireless. In mobile ad-hoc networks, the data tends to be intercepted by malicious node when using a single path for transmission. Also, the wireless channel in a mobile ad-hoc network is accessible to both legitimate network users and malicious attackers. So, the task of finding good solutions for these challenges plays a critical role in achieving the eventual success of mobile ad-hoc networks.
