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.chiggate.com/mitski-be-the-cowboy-lp-coke-bottle-clear-on-sale/
