dc.description.abstractWe study transmission schemes for lifetime maximization in wireless sensor networks. Specifically we consider the network where all the sensors observe uncorrelated signals and forward the quantized observations to a common fusion center. We demonstrate how the minimum node lifetime is maximized under individual estimation accuracy constraints through adapting transmission times and powers assigned to different sensor nodes. A partially distributed algorithm is proposed to implement joint time sharing and power control, for which each sensor node only needs local information and little common information. In addition, we obtain a necessary and sufficient condition for convergence of the algorithm. Simulation results show a significant lifetime gain over existing schemes, especially when the sensing environment becomes more heterogeneous and the number of nodes increases. © 2007 IEEE.
