近年来，移动空中基站(ABSS)的利用引起了人们的广泛关注。因此，路径规划以优化给定的效用函数，特别是机械能，一直是许多研究的主题。该领域的大部分工作都是面向用户的，即针对给定的用户位置进行路径规划。在这封信中，我们提出了一种非面向用户的路径规划方案，该方案基于一族螺旋形曲线，在能量方面是有效的，并且可以为小区内的所有用户提供相当均匀的覆盖。我们表明，与文献中已提出的径向路径相比，所建议的螺旋曲线将导致相当大的机械功率消耗的节省。我们还将该框架与R.Zhang等人提出的面向用户的路径规划方案在覆盖范围和能量效率方面进行了比较。
Utilization of moving aerial base stations (ABSs) has attracted a lot of attention in recent years. Accordingly, path planning to optimize a given utility function, and in particular, mechanical energy, has been the subject of many investigations. Most of the works in this area are user-oriented, i.e., the path planning is implemented for a given user location. In this letter, we propose a non user-oriented path planning scheme, based on a family of spiral shaped curves, that is efficient in terms of energy and can provide a fairly uniform coverage for all users within a cell. We show that the proposed spiral curves will result in considerable amount of saving in mechanical power consumption compared to the radial paths already proposed in the literature. We also compare the proposed framework to an existing user-oriented path planning scheme, proposed by R. Zhang et al., in terms of coverage and energy-efficiency.
