Anamika, Kalpana Tyagi . Secure Approach for Location Aided Routing in Mobile Ad Hoc Network. International Journal of Computer Applications. 101, 8 ( September 2014), 24-27. DOI=10.5120/17708-8711
Mobile Ad-hoc Networks (MANETs) are self-managing network which consists of distributed nodes that communicate with each other through wireless links with no fixed infrastructure and no centralized control. Due to self-configuring and dynamic nature of these networks routing protocol are susceptible to various types of attacks. The black hole attack is one of the noticeable security threats in MANETs. In Black hole attack the packet is redirected to a node that actually does not exist in the network. This paper, presents an approach to overcome black hole in MANETs. In proposed work nodes validate each other by issuing security certificate in digital form to all the other nodes in the network. The proposed method is to be adapted on Location Aided Routing Protocol with Dynamic Adaptation of Request Zone (LARDAR) protocol. This method is capable of detecting and removing black hole nodes in the MANETs. In addition information about angle ? is kept on route request packet to select optimal path for secure transmission of data packets.
