  In this work, we will consider the star network scenario where the central
party is trusted while all the edge parties (with a number of $n$) are
untrusted. Network steering is defined with an $n$ local hidden state model
which can be viewed as a special kind of $n$ local hidden variable model. Two
different types of sufficient criteria, nonlinear steering inequality and
linear steering inequality will be constructed to verify the quantum steering
in a star network. Based on the linear steering inequality, how to detect the
network steering with a fixed measurement will be discussed.
