Optimal Power Allocation for Active and Passive Localization

Power resource allocation is crucial for localization since it affects not only the conventionally recognized lifetime, throughput, and covertness, but also localization efficiency of the network. In this paper, the authors present an optimization framework for range-based localization to improve the power efficiency and localization accuracy. Their framework unifies the analysis for active and passive localization through the examples of Wireless Network Localization (WNL) and Multiple Radar Localization (MRL). In particular, they determine the functional properties of localization accuracy metric, and based on those properties they formulate the power allocation problem as conic programs.
