海洋上空FANET中基于能量均衡的自适应AODV路由协议
首发时间:2019-09-16
摘要:随着对海洋价值的不断重视与无人机技术的不断增强,在海洋上空部署由UAV构成的飞行无线自组织网络(FAENT)具有很高的军事与民用价值。路由协议是无线移动自组织网络不可或缺的一部分。与传统Ad hoc网络相比,FAENT具有节点移动速度快、拓扑变化大等特点,经典路由协议不能完全适用。本文的目的是提出基于能量均衡的自适应AODV路由协议EA-AODV。改进的AODV路由协议充分分析了UAV与FANET的特点,共同考虑能量、拥塞程度、距离三种参数,同时引入蚁群算法以选择最合适的下一跳节点,尽可能地保持整个系统的路由长期稳定工作。使用NS-3对改进的协议进行网络仿真,结果表明新协议具有较高的数据包传输率与较低的开销,提升了FANET的性能。

Energy-balance-based Adaptive AODV in FAENT over the Ocean
Abstract:With the constant emphasis on ocean value and the continuous enhancement of UAV technology, the deployment of Ad-hoc networks consisting of UAVs(FANET) over the ocean has high military and civilian value. Routing protocols are an integral part of wireless mobile ad hoc networks. Compared with the traditional Ad hoc network, FAENT has the characteristics of fast node movement and large topology change. The classic routing protocol cannot be fully applied. The purpose of this paper is to propose the adaptive AODV routing protocol based on energy balance,EA-AODV. The improved AODV routing protocol fully analyzes the characteristics of UAV and FANET. In the new protocol, three parameters of energy, congestion degree and distance are considered together, and ant colony is introduced in order to select the most suitable next hop node and keep the routing of the entire system as long as possible. The network simulation of the improved protocol using NS-3 shows that the new protocol has higher packet transmission rate and lower overhead, which improves the performance of FANET.
