论文摘要
无人机（UAV）具有更改未来无线传感器网络（WSN）的极大潜力。基于无人机的WSN性能受不同系统参数的影响。为了调查此问题，有必要分析系统参数对基于无人机的WSN性能的影响。在本文中，我们根据TCP/IP模型的层次结构方式为基于无人机的WSN设计NS-3脚本。我们通过使用NS-3模型对象配置所有图层，并设置并修改对象使用的值，以研究系统参数（访问机制，无人机轨迹模式，无人机速度，传感器数量和传感器交通传输速率）对吞吐量的影响和平均延迟。仿真结果表明，RTS/CTS访问机制比基本数据访问机制和已开处方的移动性模型提供了更好的性能，该模型显示出比随机移动性模型更高的性能。此外，结果表明，较高的无人机速度会因吞吐量和延迟而降低系统性能。我们的设计程序代表了新的NS-3用户设计和修改脚本的良好指南，结果极大地使网络设计和管理受益。
Unmanned Aerial Vehicle (UAV) has extreme potential to change the future wireless sensor network (WSN). The UAV-based WSN performances is influenced by different system parameters. To investigate this issue, it is necessary to analyses the effects of system parameters on the UAV-based WSN performance. In this paper, we design a NS-3 script for UAV-based WSN according to the hierarchical manner of TCP/IP model. We configure all layers by using NS-3 model objects and set and modify the values used by objects to investigate the effects of system parameters (access mechanism, UAV trajectory pattern, UAV velocity, number of sensors, and sensor traffic generation rate) on throughput, and average delay. The simulation results show that the RTS/CTS access mechanism provides better performance than the basic data access mechanism and the mobility model which has been prescribed shows higher performance than the random mobility model. Moreover, the results indicate that higher velocity of UAV degrades the system performance in terms of throughput and delay. Our design procedure represents a good guideline for new NS-3 users to design and modify script and results greatly benefit the network design and management.
