  Experimental demonstration of entanglement needs to have a precise control of
experimentalist over the system on which the measurements are performed as
prescribed by an appropriate entanglement witness. To avoid such trust problem,
recently device-independent entanglement witnesses (\emph{DIEW}s) for genuine
tripartite entanglement have been proposed where witnesses are capable of
testing genuine entanglement without precise description of Hilbert space
dimension and measured operators i.e apparatus are treated as black boxes. Here
we design a protocol for enhancing the possibility of identifying genuine
tripartite entanglement in a device independent manner. We consider three mixed
tripartite quantum states none of whose genuine entanglement can be detected by
applying standard \emph{DIEW}s, but their genuine tripartite entanglement can
be detected by applying the same when distributed in some suitable entanglement
swapping network.
