%X The problem of data transmission in energy-constrained wireless sensor networks is modeled into a network utility maximization problem. This model describes the coupled nature of the energy consumption among different sensor nodes. The network utility maximization is solved by introducing the slack variables and using dual decomposition techniques, and a distributed energy control algorithm is obtained. Simulation results show that, the distributed algorithm can converge to the Pareto optimal tradeoff between data rates and energy consumption for all sensor nodes.
