•Dynamical equation of thin-shell wormhole joining two identical copies of non-singular Bardeen-de Sitter spacetime is constructed.•The stability of the Bardeen-de Sitter wormhole is analyzed about the static solution of linear perturbation at the wormhole throat.•The variable modified generalized Chaplygin gas equation of state is considered.•The existence of Bardeen-de Sitter parameters and the equation of state parameters seems to enlarge the stability regions.
A dynamical equation of thin-shell wormhole joining two identical copies of non-singular Bardeen-de Sitter black hole spacetime through the cut and paste techniques is constructed. The stability of the Bardeen-de Sitter wormhole, as the static solution of linear perturbation at the wormhole throat and a variable modified generalized Chaplygin gas equation of state, is analyzed.
The existence of stability configurations depends on the particular values of different parameters involved in the equation of state as well as the space-time metric performed. The existence of Bardeen-de Sitter parameters and the equation of state parameters to enlarge the stability regions may be obtained.
