A Fractional Programming Method for Target Localization in Asynchronous Networks
IEEE Access, 2018 In this paper, we address the target device localization problem in the asynchronous networks. For the purpose of saving power resources, the target device is not synchronized with the anchor nodes, but is only required to listen to the signals ...
