Minimizing the Maximum Interference is Hard (0802.2134v2)
Published 15 Feb 2008 in cs.NI and cs.CG
Abstract: We consider the following interference model for wireless sensor and ad hoc networks: the receiver interference of a node is the number of transmission ranges it lies in. We model transmission ranges as disks. For this case we show that choosing transmission radii which minimize the maximum interference while maintaining a connected symmetric communication graph is NP-complete.
