Study of improved hierarchical ant colony routing algorithm for low-voltage power line communication

This paper proposes an improved hierarchical ant colony routing algorithm for low-voltage power line communication. The algorithm uses artificial cobweb method to reorganize the low-voltage power line communication network that is divided into multiple hierarchical networks consists of cobweb subnet. Based on this strategy, hierarchical ant colony routing algorithm will find a optimal route in order to combine the base station and one of any node in the network. Also, this algorithm solves the routing optimization problem between low voltage power line backbone network and local area network, and provides a new method to improve the low-voltage power line communication reliability. The simulation results show that the algorithm can effectively extend the distance of the low-voltage power line and improve the efficiency, which will provide reference for the engineering application.
