Performance analysis of power line communication network model based on spider web

To enhance the reliability of narrowband PLC (Power Line Communication) in low-voltage network, inspired by the structure and invulnerability of spider web, a new PLC network model is proposed in this paper. The characteristics of the model and the transformational process of low-voltage distribution network from physical topology to artificially spider web logical topology are thoroughly discussed. New networking algorithm and route reconstruction algorithm are put forward. A two-state Markov model is used to simulate a terminal node and the time-delay characteristic of the new algorithm is analyzed by modeling. Based on Opnet14.5, simulation and comparison are conducted, which prove that the new network model has advantages in improving the communication reliability of PLC network.
