In the mSUGRA model, the value of the neutralino relic density is well beyond WMAP. In order to abtain the correct relic abandance of neutralinos, we examine the aspects of DM in the NUGM(Non-Universal Gaugino Mass) case which allows a mixed wino-bino lightest SUSY particle(LSP). In our study, we investigate rates for indirect detection of neutralinos via detection of muons in neutrino telescope, and detect of photons, positrons and anti-protons by balloon and space based detectors. We find the measured wino content of the LSP and reduced mass difference between the lightest neutralinos can have effects on the depletion of relic neutralino density. It means Z2 two body decay modes are closed so that the mass reconstructions at LHC should be simpler. Finally, we conclude that measurement of the Z2-Z1 mass gap at the CERN LHC and various sparticle masses and cross sections as a function of the electron beam polarization at the ILC(International Linear Collider) will indicate the existence of MWDM(Mixed Wino Dark Matter).
