RIASSUNTO
Traditional methods require a wired network. This is overcome by the usage of MANETs which requires only wireless networks. MANET is a movable infrastructure less property which is used in military applications, battlefield, emergency recovery applications etc. Black hole attack, worm hole attack, jelly fish attack, packet dropping attack are some of the few attacks which are possible in the nodes of MANET which acts as a host and a router. Here we propose the mixed Enhance Adaptive Acknowledgement Scheme (EAACK) and Hybrid Encryption scheme to secure the MANET. Compared to other approach EAACK and Hybrid Encryption Scheme used together gives better improvement in result.
