We consider anisotropies in the stochastic background of gravitational-waves
(SBGW) arising from random fluctuations in the number of gravitational-wave
sources. We first develop the general formalism which can be applied to
different cosmological or astrophysical scenarios. We then apply this formalism
to calculate the anisotropies of SBGW associated with the fluctuations in the
number of cosmic string loops, considering both cosmic string cusps and kinks.
We calculate the anisotropies as a function of angle and frequency.
