We consider the problem of weighted sum-rate maximization (WSRMax) in wireless networks. This problem is known to be NP-hard and it plays a central role in resource allocation, link scheduling or in finding achievable rate regions for both singlecast and multicast networks. We propose a solution method, based on the branch and bound technique, which solves globally the WSRMax problem with an optimality...
We consider the problem of weighted sum-rate maximization (WSRMax) for a set of interfering links. It plays a central role in resource allocation, link scheduling or in finding achievable rate regions for both wireline and wireless networks. This problem is known to be NP-hard. We propose a solution method, based on the branch and bound technique, which solves globally the nonconvex WSRMax problem...
We consider the problem of weighted sum-rate maximization (WSRMax) for an arbitrary set of interfering links. This problem is known to be NP-hard; therefore, it is extremely difficult to solve even for a relative small number of links. The main contribution of this paper is to provide a solution method, based on the branch and bound technique, which solves WSRMax problem with an optimality certificate...
