Abstract

For a fixed integer k≥0, a k-transmitter is an omnidirectional wireless transmitter with an infinite broadcast range that is able to penetrate up to k “walls”, represented as line segments in the plane. We develop lower and upper bounds for the number of k-transmitters that are necessary and sufficient to cover a given collection of line segments, polygonal chains and polygons.

  1. The bound ⌈n/(2k+2)⌉ stated in Theorem 7 from Aichholzer et al. (2009b) is a typo.
