One of the key technologies in smart cities is the use of next generation networks such as 5G networks. Mainly because this new mobile technology offers massive connections in densely populated areas in smart cities, thus playing a crucial role for numerous subscribers anytime and anywhere. Indeed, all the most important infrastructure to promote a connected world is being related to next generation networks. Specifically, the small cells transmitters is one of the 5G technologies more relevant to provide more connections and to attend the high demand in smart cities. In this article, a smart small cell positioning is proposed in the context of a smart city. The work proposal aims to do this through the development of a hybrid clustering algorithm with meta-heuristic optimizations to serve users, with real data, of a region satisfying coverage criteria. Furthermore, the problem to be solved will be the best location of the small cells, with the minimization of attenuation between the base stations and its users. The possibilities of using multi-objective optimization algorithms based on bioinspired computing, such as Flower Pollination and Cuckoo Search, will be verified. It will also be analyzed by simulation which power values would allow the continuity of the service with emphasis on three 5G spectrums used around the world: 700 MHz, 2.3 GHz and 3.5 GHz.
智慧城市的关键技术之一是使用下一代网络,如5G网络。主要是因为这种新的移动技术能在智慧城市人口密集地区提供大量连接,从而随时随地为众多用户发挥关键作用。事实上,推动互联世界的所有最重要基础设施都与下一代网络相关。具体而言,小基站发射机是5G技术中与提供更多连接以及满足智慧城市高需求更为相关的技术之一。本文在智慧城市背景下提出了一种智能小基站定位方法。该工作方案旨在通过开发一种具有元启发式优化的混合聚类算法来实现这一目标,以服务于满足覆盖标准的区域内使用真实数据的用户。此外,要解决的问题将是小基站的最佳位置,同时使基站与其用户之间的衰减最小化。将验证使用基于生物启发式计算的多目标优化算法(如花粉授粉算法和布谷鸟搜索算法)的可能性。还将通过仿真分析哪些功率值能够保证服务的连续性,重点关注全球使用的三个5G频段:700兆赫兹、2.3吉赫兹和3.5吉赫兹。
