| Abstract | Mobile Ad Hoc Network (MANET) is a collection of wireless mobile nodes that dynamically function as a network without the use of any existing infrastructure and centralized administration. The mobile nodes must cooperate at the routing level in order to forward packets to from source to the destination. Current ad hoc routing protocols such as DSR assumes the network is benign and cannot cope with misbehavior, i.e., a misbehavior node may drop packet silently to save battery power, etc.
Dynamic feedback mechanism has been recently introduced to mitigate the misbehavior in MANET. The idea is to build the trust relationship between the mobile nodes in the MANET and select routes based on the formed trust values. CONFIDANT is a dynamic feedback mechanism in which mobile nodes monitor the behavior of their neighbors and exchange first hand information about other nodes in the MANET. This allows other nodes to change their reputation value accordingly and thus identify the misbehaved nodes.
This thesis investigates dynamic feedback mechanisms as security solutions for MANET, implements CONFIDANT protocol using ns2 as simulation environment, and evaluates the performance of CONFIDANT fortified DSR in the MANET where misbehaved nodes present. |
