ABSTRACT

Protection against covert security breaches across mobile ad hoc networks is hard to achieve due to the dynamic and decentralized topology of these networks. The covert channels in wireless network involves complicated manipulations to convey covert information. Since they are decentralized the style of operations in each node has to be handled individually. The routing algorithms had to be dynamically adaptable to network topology changes providing correct routes between communicating users in a timely and efficient manner. The paper investigates ad-hoc wireless networks’ susceptibility to covert channels by manipulating the network protocols which is very difficult to eliminate or even detect these covert channels. The work also analyses concept of covert channels and investigates susceptibility aspects of some of the ad hoc routing protocols to find out the possible countermeasures.

Keywords: Covert channel, Ad hoc protocol, Communication models.
