However, a large number of device connection under a limited bandwidth unavoidably degrades the transmission efficiency of a wireless network.<\/div><div>\u00a0<\/div><div style=\"text-align: justify; font-size: medium;\">To address the above problem, Dr Yaru Fu, Assistant Professor in the School of Science and Technology at Hong Kong Metropolitan University (HKMU), conducted a research project aiming at achieving a breakthrough in minimising the latency of a wireless network. This project examined the utilisation of the technology of caching on content retrieval to support non-orthogonal multiple access \u2014 a 5G technology enabling multiple access for users at the same time \u2014 to improve the probability of signal coverage in a wireless network. In addition, the project exploited the recommendation system technology for shaping network users' content request behaviours to increase the cache hit ratio \u2014 an indicator of network performance \u2014 so as to further reduce network latency.<\/div><div>\u00a0<\/div><div style=\"text-align: justify; font-size: medium;\"><img decoding=\"async\" loading=\"lazy\" class=\"wp-image-15391 alignleft\" src=\"https:\/\/www.hkmu.edu.hk\/wp-content\/uploads\/sites\/15\/2023\/03\/Joint-Optimisation_Image-1-1.png\" alt=\"\" width=\"438\" height=\"312\" srcset=\"https:\/\/www.hkmu.edu.hk\/ora\/wp-content\/uploads\/sites\/15\/2023\/03\/Joint-Optimisation_Image-1-1.png 1559w, https:\/\/www.hkmu.edu.hk\/ora\/wp-content\/uploads\/sites\/15\/2023\/03\/Joint-Optimisation_Image-1-1-300x214.png 300w, https:\/\/www.hkmu.edu.hk\/ora\/wp-content\/uploads\/sites\/15\/2023\/03\/Joint-Optimisation_Image-1-1-1024x729.png 1024w, https:\/\/www.hkmu.edu.hk\/ora\/wp-content\/uploads\/sites\/15\/2023\/03\/Joint-Optimisation_Image-1-1-768x547.png 768w, https:\/\/www.hkmu.edu.hk\/ora\/wp-content\/uploads\/sites\/15\/2023\/03\/Joint-Optimisation_Image-1-1-1536x1094.png 1536w\" sizes=\"(max-width: 438px) 100vw, 438px\" \/><\/div><div style=\"text-align: justify; font-size: medium;\">\u00a0<\/div><div style=\"text-align: justify; font-size: medium;\">Noticing the effective interplay between the above technologies, Dr Fu's team developed an algorithm to optimise network content caching, recommendation, and transmission to improve the overall performance of a wireless network. Their proposed algorithm was evaluated through extensive simulations to verify its performance in comparison to other baseline methods. The results demonstrated that their algorithm achieves a significantly lower latency and better cache hit ratio than others in real-life 5G network scenarios. The achievements of the research team provide insights to the network industry in developing the next generation of wireless networks.<\/div><div>\u00a0<\/div><div style=\"text-align: justify; font-size: medium;\">These research findings were published in the scientific journal <em>IEEE Journal on Selected Areas in Communications<\/em> with the paper title <a href=\"https:\/\/ieeexplore.ieee.org\/document\/9704870\">'Joint content caching, recommendation, and transmission optimization for next generation multiple access networks'<\/a>.
