In this paper, optics-based sensor node localization using MEMS (Micro Electro Mechanical Systems) CCR (Corner Cube Retro-reflector) array is studied. Since CCR is a device which is made up three mutually orthogonal mirrors, an incident ray sent toward CCR can be reflected back in the opposite direction of the incident ray. Using this characteristic, the distance between sensor node and source can be calculated by measuring the difference in detection time of source and sink. However there is a short detection range problem because the power of ray reflected by MEMS CCR is not strong enough to be detected. So we analyze reflection process using MEMS CCR and base station, and simulate using analysis of reflected power of ray. And we suggest MEMS CCR array instead of single MEMS CCR to overcome weak power problem and analyze the power of ray reflected by MEMS CCR array. It is expected that the analysis in this research can be utilized as a mathematical baseline of MEMS CCR to be distributed in optics-based sensor network.
