Abstract :
In this paper we provide a polynomial-time 2-approximation algorithm for the all-to-all minimum cost range assignment problem in ad-hoc wireless networks that can be modelled by generic directed weighted graphs. The best already known approximation algorithm has a logarithmic approximation fact.
