Abstract: Techniques for utilizing Software-Defined Field-Area Network (SD-FAN) controllers to receive a geographic location and transmission power of individual nodes and generate a geographic location topology of a Field-Area Network (FAN) to provide nodes with location-aware route paths for data transmission. One or more SD-FAN controller(s) may maintain a geographic location database to store the geographic location and transmission power of the individual nodes. Each node may utilize a Destination Address Object to advertise its geographic location and transmission power to the SD-FAN controller. The SD-FAN controller(s) may utilize the geographic location table to generate the geographic location topology of the FAN and determine a location-aware route path for optimized data transmission between nodes in the FAN.
