  The India-Based Neutrino Observatory (INO) collaboration houses the miniICAL
detector, at the transit campus of IICHEP, Madurai, India, which serves as a
prototype-detector of the larger Iron-Calorimeter detector (ICAL). The purpose
of miniICAL lies in unraveling the intricate engineering challenges inherent in
constructing a substantial ICAL-type detector. To explore the feasibility of
building a large-scale neutrino experiment at shallow depths the collaboration
has embarked upon the construction of a Cosmic Muon Veto Detector (CMVD) around
the miniICAL detector. The primary objective of this endeavor revolves around
attaining a veto efficiency surpassing $99.99\%$, while simultaneously
maintaining a false-positive rate lower than $10^{-5}$.
  The CMVD system is based on extruded plastic scintillators (EPS) and utilizes
wavelength-shifting fibers to collect scintillation photons and uses silicon
photomultipliers (SiPMs) as photo-transducers. The expected performance of the
CMVD is estimated using simulated muon tracks in the miniICAL stack taking into
account efficiency, multiplicity of RPC detectors from the miniICAL data as
well as the noise of SiPM, observed SiPM spectra and time resolution due to
cosmic muon along the whole length of EPS etc.
  The CMVD experiment is a crucial step in the larger context of neutrino
research, by increasing the veto efficiency of cosmic muons, the CMVD
experiment helps to pave the way for future large-scale shallow-depth neutrino
experiments, providing valuable insights into the study of neutrinos and their
properties.
