Abstract
Identification of a malicious node in the ad-hoc network is a very challenging issue due to some limitations, such as no base station or centralized server, dynamic topology, low computational capacity and limited battery power. In ad-hoc network each node having a limited range of communication to communicate with remaining nodes. Because of the limited range of communication, source node sends the packet/message with the help of intermediate neighbor nodes to the destination node. Dependency of other nodes poses security threats in ad-hoc networks. In this paper we are using Boneh-Franklin’s IBC authentication scheme before deployments of nodes in MANETs and after setup of ad-hoc network, we are using DSR protocol with trust value of each node to find out a secure route between source and destination nodes. Trust-based DSR protocol will find a route that is free from black hole nodes. From security analysis, we have shown that the proposed scheme is providing the secure communication in MANETs.
