In this paper, we study asymmetric power assignments that induce a low-energy k-strongly
connected communication graph with spanner properties. We address two spanner models …

The temporary and unfixed physical topology of a wireless ad-hoc network is determined by
the distribution of the wireless nodes as well as the transmission power (range) assignment …

Topology control is the problem of assigning power levels to the nodes of an ad hoc network
so as to create a specified network topology while minimizing the energy consumed by the …

Given a wireless network, we want to assign each node a transmission power, which will
enable transmission between any two nodes (via other nodes). Moreover, due to possible …

Symmetric disk graphs are often used to model wireless communication networks. Given a
set S of n points in ℝ d (representing n transceivers) and a transmission range assignment r …
