We investigate the cosmic rays transport in the distant heliosheath, by tracking stochastic phase-space trajectories of Parker equation under the steady heliosheath background; the latter is obtained from the global MHD simulations, and the warped current sheet is taken into account. Different inner boundary conditions of the heliosphere and outer boundary conditions of the local interstellar medium (LISM) are set to obtain various wavy current sheet structures that cover the most latitudes in the heliosheath. Moreover, the global distribution of heliosphere is compared with what could be deduced from IBEX neutral hydrogen maps. We deduce the physical quantities of the LISM based on the comparison between the observed IBEX evidences and the simulation results.
