Power Allocation for multi-target sensor networks


E. Zandi, G. Alirezaei, R. Mathar,


        This paper regards a network of wireless passive sensors, suitable for radar applications. The network observes multiple number of target signals to be estimated. We propose an unbiased estimator whose error is minimized by optimizing both the power allocation at sensor nodes and the fusion coefficients at the fusion center. Since the underlying optimization problems are subject to both the individual power constraints of sensor nodes and a sum-power constraint of the sensor network, the corresponding solution describes an optimized policy for efficient power allocation to the sensor nodes and enables an energy-aware operation of the sensor network. The results are compared via numerical simulations.
