Abstract

Mobile collectors (MCs), such as unmanned aerial vehicles (UAVs), play a crucial role in conserving energy and enhancing the longevity of wireless sensor networks (WSNs) compared to static sinks. The implementation of efficient routing algorithms and scheduling mechanisms tailored for MCs is of utmost importance. In response to this challenge, we propose an innovative data collection method called energy- density-based trajectory planning (EDTP) specifically designed for WSNs equipped with MCs. First, we introduce a global energy-difference density optimization scheme (GEDD) to select cluster heads (CHs) responsible for transmitting data to MCs. The selection of CHs aims to balance the energy consumption of nodes, thereby extending the system's lifespan. Second, we propose the K-dimension tree grouping algorithm (KDTG) with high computational efficiency to group CHs based on their geographical similarity. Comparisons with three existing approaches demonstrate that our proposed EDTP method can significantly increase system lifetime and reduce latency.

一种基于能量密度的移动收集器无线传感器网络轨迹规划方法

与静态接收器相比，移动收集器（mc），如无人机（uav），在节约能源和延长无线传感器网络（wsn）寿命方面发挥着至关重要的作用。实现针对mc的高效路由算法和调度机制是至关重要的。为了应对这一挑战，我们提出了一种创新的数据收集方法，称为基于能量密度的轨迹规划（EDTP），专为配备mc的wsn设计。首先，我们引入了一种全局能量差密度优化方案（GEDD）来选择负责向mc传输数据的簇头（CHs）。CHs的选择旨在平衡节点的能量消耗，从而延长系统的使用寿命。其次，我们提出了计算效率高的k维树分组算法（KDTG），基于地理相似性对CHs进行分组。与三种现有方法的比较表明，我们提出的EDTP方法可以显着提高系统寿命并减少延迟。
