Research on 5G network base station site selection based on fruit fly optimization algorithm
Published 2023-10-01“…Faced with the fact that the spatial distribution of buildings is not considered in the location of 5G network base stations, which makes the base station site selection effect unsatisfactory and leads to the problem of small coverage of base stations, a research method for 5G network base station site selection based on fruit fly optimization algorithm was proposed.The distance from the front line base station to the circular coverage center was calculated, and the satellite communication equipment was used to locate the return signal to obtain the optional position area of the rear base station.The energy consumption of data reception, transmission and aggregation were calculated, and the load balancing of base station data was ensured under the premise of balanced distribution of cellular units.A two-layer location model for base station site selection was built, constraints were set, and the optimal location of base station was determined.The fruit fly optimization algorithm was used to update the position, and after individual update iterative processing, it was not to fall into local optimization and obtain the fine base station site selection position.It can be seen from the experimental results that the minimum losses of the front line and rear base stations in this method are 50 dB and 70 dB, respectively, and the coverage radius of the base station is 6 km, which is consistent with the coverage of the ideal base station.…”

The Mentoring Experiences of Early Career and Senior Academics in a Multicampus University in South Africa
Published 2022-03-01“…Results – The study’s results revealed that the mentoring experiences of ECAs could be enhanced by, among other things, institutional arrangements designed to address the mentoring needs of ECAs in terms of teaching, researching, researcher rating and engaged scholarship, establishment of clear communication channels that inform ECAs across the different campuses of the various professional development programs available, and the appointment and training of established academics especially at the satellite campuses to mentor ECAs. Conclusion – To enhance the professional and personal development of ECAs, the university must establish an institutional mentoring framework that focuses on equal distribution of resources across all campuses, the adaptation of ECAs to the unique university environment, and promoting professional relationships between established academics and ECAs.…”

Space-air-ground integrated networks:review and prospect
Published 2020-09-01“…With the advance of the information technologies,the scale of the information services gradually expands,from ground services,to aerial,maritime,and spatial services,with the soaring requirements on multi-dimensional comprehensive information resources.The space-air-ground integrated networks (SAGINs) are envisioned to provide seamless network services to spatial,aerial,maritime,and ground users,satisfying the future network requirements on all-time,all-domain,and all-space communications and interconnected networking.Firstly,we reviewed the current research development of SAGINs,discussing the research trends on the low-earth orbiting (LEO) satellite constellation and space-ground network integration.Then,the reinforcement learning (RL) framework was proposed in SAGINs to address the problems of complex architecture,high dynamics,and resource constraints in SAGINs,which facilitated efficient and fast network design,analysis,optimization,and management.As a case study,the method of applying deep RL (DRL) was showed for the intelligent access network selection in SAGINs.To improve the RL training efficiency,a comprehensive SAGINs simulation platform was established,through which the agent-environments interaction was accelerated and training samples could be obtained more cost-effectively.Finally,some open research directions were presented.…”
