Abstract -
A mobile ad hoc network is a wireless network in which no infrastructure is available. MANET is a self-configuring network. Due to dynamic nature of MANET it is very challenging work to employ a secure route. The intermediate nodes cooperate with each other as there is no such base station or access point. The routing protocols play important role in transferring data. Cryptographic mechanisms are used in routing protocols to secure data packets while transmitted in the network. But cryptographic techniques incur a high computational cost and can’t identify the nodes with malicious intention. So, employing cryptographic techniques in MANET are quite impractical as MANETs have limited resource and vulnerable to several security attacks. Trust mechanism is used as an alternative to cryptographic technique. Trust mechanism secures data forwarding by isolating nodes with malicious intention using trust value on the nodes. The most important aspect of the proposed system is that it is able to identify the selfish nodes or the attackers in the two-hop neighbours also, as opposed to other watchdog techniques which can detect selfish nodes in one-hop neighbours only. The attackers are having a trust value less than the threshold trust value and such nodes are eliminated from the route. If one node finds that one of its onehop neighbours or two-hop neighbours is an attacker, then the corresponding change is made in the so called trust table so that other nodes will also be aware of the attackers and thereby they can avoid them while selecting the route to send their packets. This helps to achieve a packet drop of zero or a packet delivery ratio of one in all the cases, thus improving the overall efficiency of the network.
