In MANETs, exchange of data is carried out with the help neighbouring nodes, and the destination node is identified with the broadcasting schemes. Broadcasting schemes are considered to increase the efficiency, and MPR broadcasting scheme is considered because of its reduced overhead. The message is broadcasted only to the selected MPR nodes, thus reducing flooding in the network. Nodes that are selected to act as the MPR nodes can be any neighbouring nodes, and there are no significant conditions that prove the MPR node's integrity. In this paper, we have proposed a novel approach in selecting the MPR nodes by adding an additional security feature before MPR node selection. Our security feature does not add any additional communicational overhead or data exchanges. We were also able to reduce the localisation error by using Mahalanobis distance and maximum-likelihood. Localisation techniques were used during simulation to verify the time constraints and efficiency.
