Abstract: E-textiles are an alternative to radio-based personal area networks, with potentially significant advantages in hardware cost and energy consumption, through a reduction in the number of communication modules and the energy consumed by data transmission. This paper presents a methodology based on simulation and physical experimentation for quantifying this savings on a large e-textile that determines the bearing/location of one or more distant audible targets.
