In this work, collocation method based on B-SPLINE functions is used to obtained a numerical solution for one-dimensional HYPERBOLIC telegraph equation. The proposed method is consists of two main steps. As , rst step, by using , nite di, erence scheme for time variable, partial di, erential equation is converted to an ordinary di, erential equation by space variable. In the next step, for solving this equation collocation method is used. In the analysis section of the proposed method, the convergence of the method is studied. Also, some numerical results are given to demonstrate the validity and applicability of the presented technique. The L1, L2 and Root-Mean-Square(RMS) in the solutions show the e, ciency of the method computationally.
