This paper proposes a novel approach to emulate an arbitrary wireless multi-hop network scenario in a fixed wireless test-bed, in which every node is equipped with a variable attenuator. We take notice of the interval equivalent character of wireless communication and consider the wireless multi-hop scenario emulation problem as an interval equivalent emulation problem. We define the generalized error, which is an error of a value relative to an interval, formulate the MinGenMax (Minimize Generalized Maximum) error problem and propose an optimum algorithm.
