In this paper peristaltic transport of a power law fluid in an asymmetric channel bounded by permeable beds is studied under long wavelength and low Reynolds number assumptions. The channel asymmetry is produced by choosing the peristaltic wave train on the walls to have different amplitude and phase due to the variation of channel width, wave amplitudes and phase differences. Expressions for the velocity, pressure rise and frictional force are obtained. The effect of various parameters on these is discussed through graphs.
