Trusted and Lightweight Dynamic Source Routing (TL-DSR) Protocol To Withstand Against Selfish Attack in Mobile ad Hoc Networks Based Military Environment

Securing MANET based military environment is always a challenging task because of various security threats in the form of attacks. Among the threads, selfish behavior is one of the considerable issues in recent research because it is not launched from outside the network instead they launched from inside of the network by compromised nodes. The main objective of selfish nodes is not to involve in any network related operations so as to save their energy by the way they try serve in the network for a long time. Hence, the performance of the mission will reduce. In this paper, a Trusted and Lightweight Dynamic Source Routing (TL-DSR) protocol to withstand against Selfish soldier/nodes in MANET based military environment is proposed. The main objective of this paper is to ensure authentication by identifying selfish soldiers/nodes based on the Overall Rating (OR) which is calculated based on the soldiers' Interaction Rating (IR), Packet Forwarding Rating (PFR), Social Rating (SR) such as attitude, behavior, belief, honest and responsibility of soldiers.
