Systems, apparatuses, and methods for determining locations of wireless nodes in a network architecture are disclosed herein. In one example, a system for localization of nodes in a wireless network architecture, comprises a wireless node having a wireless device with one or more processing units and RF circuitry for transmitting and receiving communications in the wireless network architecture; and a plurality of wireless sensor nodes having a wireless device with a transmitter and a receiver to enable bi-directional communications with the wireless node in the wireless network architecture. One or more processing units of the wireless node are configured to execute instructions to determine ranging data including a set of possible ranges between the wireless node and the plurality of wireless sensor nodes having unknown locations, and to associate a set of relative locations within an environment of the wireless network architecture with the wireless node and the plurality of wireless sensor nodes.
