We　propose　a　linear　optical　protocol　to　generate　Greenberger-Horne-Zeilinger　(GHZ)　state　under　control　of　a　number　of　controllers　in　terms　of　optical　elements.　The　proposed　setup　involves　simple　linear　optical　elements,　(N-1)-photon　polarization　entangled　state,　and　conventional　photon　detectors.　We　show　that　the　protocol　can　be　successfully　realized　with　a　certain　probability.
