DESCRIPTION:We consider random walks on marked simple point processes with
  symmetric jump rates and unbounded jump range.  Examples are given by \ns
 imple random walks on Delaunay triangulations or  Mott variable range hopp
 ing\, which is a fundamental mechanism of phonon–induced electron conduc
 tion in amorphous solids as doped semiconductors.  We present  homogenizat
 ion  results for  the associated Markov generators. As an application\, we
  derive the hydrodynamic limit of the simple exclusion process given by mu
 ltiple random walks as above\, with hard–core interaction\, on a marked 
 Poisson point process.
