The proposed work deals with the improvisation of the performance of location-based routing in mobile ad hoc network (MANET). A machine learning-based attacker detection (MLAD) algorithm that uses multipath routing is proposed to facilitate efficient routing even in the presence of attackers. The proposed algorithm adopts the location aided routing (LAR) to optimise the search process and to reduce the search area for new routes in MANETs. Learning automata (LA) is implemented to optimise the path selection and to reduce overhead in the network. Extended identity-base cryptography (EIBC) is used for efficient key management in providing system security. The proposed system implements privacy preserving communication system (PPCS) for maintaining privacy in end-to-end communication. This method decouples the location information from the node's identifier and abstracts the communication happening among nodes. The simulation results of the proposed method reveal its reliability and strength in securing LAR in MANETs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
