Abstract
In this paper we formulate a novel utilitycost optimization problem for routing and power control in multihop wireless networks. As the problem is nonconvex and nonseparable (no assumption on high or low SINR regime), we approach it by solving a sequence of convex approximation problems. If the initial convex approximate is feasible, it is shown that the solution sequence converges to a KKT point to the original utilitycost optimization problem. The convex approximation problems are solved recursively by means of primaldual methods that are shown to be amenable to distributed implementation. The seamless interaction between the successive convex approximation and the primaldual algorithm constitutes the proposed successive primaldual convex approximation (SPDCA) algorithm.
