The　Internet　of　Things　(IoT)　is　a　progressive　field　in　communication.　An　important　concept　of　the　IoT,　which　has　a　deep　influence　on　its　progress,　is　security.　There　are　many　approaches　to　improve　security　in　networks,　but　some　of　them　are　not　useful　due　to　technical　limitations.　In　this　paper,　we　present　a　new　approach　that　improves　security　in　communication　with　Intelligent　Automata　(IA).　IA　is　an　evolutionary　approach　that　has　the　capability　to　overcome　the　technical　limitations　of　a　network.　We　compare　the　results　of　IA　with　the　results　of　multi-objective　simulated　annealing　(AMOSA).　©　2016　IEEE.
