Abstract: In order to solve the problems of bandwidth bottleneck and high latency in chain-type wireless communication network of transmission line online monitoring, a hybrid hierarchical communication network planning model and the corresponding multi-objective decision-making method are proposed. A network planning model of fiber-optic separation tower placement is formulated with objects of placement costs and end-to-end latency optimization, while satisfying the constraints of graph-based path connectivity and bandwidth. Particle swarm optimization algorithm is used to solve the model, so as to obtain the Pareto optimal solution set. The most satisfactory network planning scheme is selected by the multi-attribute decision-making method based on fuzzy entropy weight of vague set. Finally, the effectiveness of the proposed model and algorithm is validated by results of the case study. Besides, the impacts of the subjective weight, the data rate and network scale on the decision-making are analyzed.
