In hostile environments. localization often suffers from malicious attacks that may distort transmit power and degrade positioning accuracy significantly for wireless sensor network. A robust semidefinite relaxation secure localiza-tion algorithm RSRSL was proposed to improve the location accuracy against malicious attacks. On the assumption of unknown transmit power. https://www.roneverhart.com/6-Pack-Acrylic-Round-Charger-Plates-13-in-Terracotta-Rust-with-Gold-Scalloped-Rim-Decorative-Dinner-Party-Plastic-Cha/
