Embodiment Construction

[0032] A hierarchical ant colony routing method for low-voltage power lines based on non-overlapping clustering. The large-scale node network is divided into multiple sub-networks through the non-overlapping clustering method, and then ant colony algorithm is used to construct communication routes between sub-networks, thereby establishing Routing model of low-voltage power line hierarchical communication network.

[0033] Please check figure 1 , the non-overlapping clustering method includes the following steps:

[0034] Step 1. The concentrator / cluster head broadcasts a networking request. If the terminal node detects the request, it sends a response message to the concentrator / cluster head. The concentrator / cluster head selects k nodes from the nodes whose signal strength is greater than the threshold β. The cluster head, the cluster head selection strategy is divided into k gradient segments according to the order of the node signal strength, and the node with the stronge...

Abstract

The invention discloses a low-voltage power line layered ant colony routing method based on non-overlapping clustering, which divides a large-scale node network into multiple sub-networks through the non-overlapping clustering method, and then uses the ant colony algorithm to construct communication between the sub-networks Routing, so as to establish a low-voltage power line layered communication network routing model. It has the following advantages: greatly reducing the number of nodes that the ant colony algorithm needs for communication routing, and solving the problem of low time efficiency of the ant colony algorithm, so that the entire network is built faster and more real-time.

Description

technical field [0001] The invention relates to a low-voltage power line layered ant colony routing method based on non-overlapping clustering. Background technique [0002] Ant colony optimization (ACO) is a heuristic bionic algorithm based on population optimization proposed by simulating the collective foraging behavior of ants in nature. There are two main steps in the ant colony algorithm, namely path construction and pheromone update. The mutual cooperation of the two makes the ant colony algorithm have positive feedback, and at the same time makes the ants converge to the optimal solution. [0003] At present, the application of ant colony algorithm to the dynamic routing of low-voltage power line carrier is one of the current research hotspots. However, the ant colony algorithm has the problems of slow convergence speed and low time efficiency. Therefore, there are some schemes to optimize the ant colony algorithm, such as genetic algorithm, particle swarm algorithm...
