  The quantum tunneling radiation of scalar particles near the event horizon of
Kerr-de Sitter black hole is investigated in three systems of coordinates
namely naive coordinate system, Painleve coordinate system and Eddington
coordinate system using Lorentz violation theory in curved space time. The
Klein-Gordon equation of scalar particles is transformed into Hamilton-Jacobi
equation by using Lorentz violation theory in curved space time. We observe
that due to Lorentz violation theory, the expressions of Hawking temperatures,
the Bekenstein-Hawking entropies and specific heat capacities near the event
horizon of Kerr-de Sitter black hole are modified. The Hawking temperatures,
entropies and specific heat capacities increase or decrease depending upon the
choices of ether like vectors $u^\alpha$
