TransmiΒion　healthcare　data　is　focused　in　this　paper.　WireleΒ　Body　Area　Network　(WBAN)　is　kind　of　Mobile　Ad　Hoc　Network　(MANET)　that　is　used　for　transmiΒion　healthcare　data.　Efficient　parameters　for　secure　routing　in　WBAN　are　specified　and　then　they　are　optimized　simultaneously.　Secure　routing　in　WBAN　is　modeled　as　an　optimization　problem.　Since　parameters　of　secure　routing　are　individuals　and　the　structure　of　WBAN　is　dynamic,　optimization　is　executed　simultaneously.　Multi-objective　optimization　algorithms　have　ability　to　optimize　multi　variables　simultaneously.　Monarchy　Butterfly　Optimization　as　a　new　and　powerful　multi-objective　optimization　algorithm　is　used　in　this　paper.　©　2017　AΒociation　for　Computing　Machinery.
