| Bibliography: | A power line communication （PLC） multi-frequency protocol simulation platform based on NS-3 network simulator is proposed and implemented to deal with the lack of evaluation and verification environment for PLC protocol. PLC module is developed based on NS-3, which realizes the physical layer, medium access control （MAC） layer and logic link control （LLC） layer functions. Based on the three-handshake of preambles, PLC module can support muhi-frequency networking and communication. Besides, the proposed PLC protocol simulation platform can not only support for typical network topology configuration, but also import measured attenuation and noise data. The test resuits shows that the proposed PLC multi-frequency protocol simulation platform could simulate and verify different MAC functions, key algorithms and parameters in different scenarios, and could evaluate nodes access probability, throughput performance, and so on, it is a powerful tool for the study of multi-frequency PLC protocol.
