Dynamic source route computation to avoid self-interference

摘要

In a multiple interface, low power and lossy network comprising a plurality of devices, interface options for a source route to minimize self-interferences are desired. The ability to request a interface technology for a device to use with neighboring devices allows multiple transmissions to occur simultaneously without interfering with each other. A root phase device obtains interface option information from the devices. Each device in a network path determines the interface options available, such as powerline communications (“PLC”) and radio frequency (“RF”). The device transmits the interface options to the parent device. The parent device transmits the interface options up the network path toward the root phase device, which collects the interface options and determines transmission routes to any needed endpoint device. The transmission route will comprise the device routes and a interface option for each hop from a parent device to a child device.
