After giving a general overview of the topic of cosmic strings I will
present an analytic model specifically designed to address the issue of
small scale structure on cosmic string networks. The model is derived from
the microscopic string equations, together with a few motivated
assumptions. The resulting form of the correlation between two points on a
string will then be exploited to study smoothing by gravitational
radiation, loop formation and lensing by cosmic strings. In addition, the
properties of the small loop population and the possibility of detecting
gravitational waves generated by their lowest harmonics will be discussed.
