Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, to mitigate a denial of service attack to a power line communication (PLC) network. A first node of the PLC network may activate a countermeasure that enables the PLC network (including the first node and a second node) to continue to communicate when one or more transmissions associated with a denial of service attack are injected onto the communication medium. This disclosure includes several techniques to detect a denial of service attack and several countermeasures that may be implemented. For example, a countermeasure may include the use of a custom preamble or a custom priority resolution symbol that is specific to the PLC network. The first node and the second node may disregard transmissions that do not conform to the custom preamble or custom priority resolution symbol.
