The scaling limits of these random walks to a diffusion process in the sense of distributions is proved. Simulations based upon multi-term fractional order differential equations are performed.18 pages. Submitted to Fractional Calculus and Applied AnalysisDynamical Systems65C05, 60G50, 39A10, 92C37text
