Abstract: 

Mobile Ad hoc Network (MANET) is an autonomous, wireless network of mobile devices with dynamic infrastructure. Despite its wide-ranging applications, MANETs are prone to network attacks eventually leading to denial of service attack resulting in packet loss. Blame it on the basic routing protocols such is their design assuming there are no malicious nodes in the network making them vulnerable to either black hole or gray hole attacks. Detection and elimination of malicious nodes involved in the packet forwarding process, is quite a challenge. Down the ages different methods have been employed for the same such as the credit based, trust based, auditing based and end to end based each having its own drawbacks. Aimed at improving the delivery ratio of packets in the network, the proposed method combines one hop  with auditor for attack prevention and detection and watchdog mechanism can be combined with auditor node which identifies malicious nodes, so that there is a high level of security in adhoc networks. By taking an extra hop of traversal a situation is created where the malicious nodes tend to drop its own packets while the auditor tries to key out nodes which are malicious leading to its subsequent elimination.
