N2 - The paper deals with the problem of power control in distributed wireless networks. The objective is to allocate transmit powers to the links so as to optimize the sum of weighted link-layer QoS levels. Instead of focusing on a specific QoS measure such as data rate, delay or bit error rate, we consider a generic framework that includes some interesting QoS metrics as special cases. The paper presents an iterative gradient based algorithm that is shown to converge to a global optimum. Moreover, we propose a simple procedure based on the use of an adjoint network that allows an efficient implementation of the algorithm in distributed networks.
