A MANET (Mobile Ad hoc NETwork) is a collection of wireless nodes that can dynamically form a network to exchange information without using any pre-existing fixed network infrastructure. The special features of MANET bring this technology great opportunity together with severe challenges. In MANET nodes can directly communicate to all other nodes within the radio communication range. In addition to the common vulnerabilities of wireless connection, an ad hoc network has its particular security problems due to e.g. nasty neighbor relaying packets. The feature of distributed operation requires different schemes of authentication and key management. In this paper, the authors proposed a novel approach "Semantic Content Based MANET", in this method firstly each MANET node must learn routing and security information using semantic genetic programming and then they uses full cache method for packet transaction in MANET.
