In the large-scale optical satellite network (LS-OSN), hundreds to thousands of low Earth orbit (LEO) satellites will be interconnected via laser links, offering global coverage characterized by high throughput and latency. LS-OSNs present an attractive strategy cultivate a comprehensively connected, intelligent world. However, dynamic nature satellites, as they Earth, results in frequent changes LS-OSN topology. Thus, there is pressing need for efficient routing algorithms that not only...
The low-Earth-orbit optical satellite network (LOSN) is an attractive solution to realize the end-to-end service quality of large-scale services, and it basis establishing 6G mobile with high throughput reliability. However, current LOSN practically unable achieve such for global access. First, centralized deployment ground gateways will cause a heavy traffic load in space segment LOSN, which becomes bottleneck constraining further growth throughput. Second, high-speed movement LEO...
A novel load-balancing routing algorithm based on satellite-ground cooperation is proposed to reduce the impact of inter-satellite link congestion in LEO satellite optical networks. Simulations prove that our proposal can significantly improve network throughput.
With the continuous expansion of electric power communication network scale, increasingly complex topology structure, rapid growth access terminals and production business, faces challenges in intelligent operation maintenance. Training a deep neural fault prediction model then constructing an transmission equipment health evaluation can quantify status improve level However, after original data collected from is preprocessed, number alarm far less than non-alarm data, distribution...
To address the health status assessment of communication equipment under various uncertainty factors, a novel evaluation method for has been developed, considering significance metrics comprehensively. This framework integrates subjective Analytic Hierarchy Process (AHP) and objective Criteria Importance Through Intercriteria Correlation (CRITIC) to determine weighting metrics. Furthermore, dynamically adjusting metric weights based on data volatility is proposed, thereby circumventing issue...
A novel routing algorithm is proposed to reduce the computation time in dynamic LEO optical satellite networks. Simulations prove that our can significantly fasten while maintaining maximum throughput.
Large-scale optical satellite networks (LS-OSNs) have emerged as critical communication infrastructures, connecting terrestrial and space to provide global signal coverage with high throughput low latency. However, optimizing network while ensuring comprehensive internet remains a challenge. In this paper, we propose the Coverage-Enhanced Flow Optimization Heuristic (CEFOH), novel approach tackle coverage-constrained multi-source multi-sink maximum flow problem in LS-OSNs. CEFOH efficiently...
