摘要
飞行自组网是移动自组网的一个新的研究方向,它将移动自组网的思想拓展到空天领域。但由于节点的高动态性和拓扑结构快速变化等特点,飞行自组网对路由协议提出更多挑战,传统移动自组网路由协议的适用性有待验证。文章利用OMNe T++仿真工具,针对飞行器组网的特定场景,对多种路由协议进行仿真,分析对比了各协议性能,探讨了无人机自组网路由协议的优选问题。实验结果表明OLSR_ETX协议综合性能优于其他几类协议,更适用于飞行自组网场景,但它在节点需要动态入网时表现不佳,还需要进一步的优化。
Flying Ad hoc network（FANET） is a new research direction in mobile ad hoc networks, which extends the idea of mobile Ad hoc networks to the field of air space. However, due to the high dynamic characteristics of nodes and the rapid change of topological structure, FANET has more challenges for routing protocols. The applicability of routing protocols in traditional mobile ad hoc networks needs to be verified. In this paper, we use OMNe T＋＋ simulation tool to simulate several routing protocols for specific scenarios of UAV networking, analyze and compare the performance of each protocol, and discuss the optimization problem of UAV routing protocol. The experimental results show that the OLSR_ETX protocol performs better than other kinds of protocols, and is more suitable for the scene of FANET. However, it performs poorly when nodes need to enter the network dynamically, and further optimization is needed.
