基于负载感知和伪流言机制的高稳定性路由协议

通过建立无人机自组网可以有效满足无人机集群作战的组网通信需求,但相较于传统移动自组网,无人机自组网具有节点移动速度更快,网络拓扑高度动态变化的显著特征.针对链路频繁断开带来网络性能下降严重的问题,提出了一种基于负载感知和伪流言机制的高稳定性路由协议.网络拥塞和节点移动性是影响路径稳定性的两个主要因素.针对网络拥塞问题,提出了基于节点负载预测的伪流言受限洪泛机制,在发起路由请求过程中,通过动态调整节点转发概率,均衡了网络负载的同时降低了控制开销.针对无人机节点的高移动性特征,基于接收到分组信号功率强度,提出了链路稳定性的联合度量指标.仿真结果表明,与AODV协议及其他改进型协议相比,该协议有效减少了网络的控制开销,提高了分组投递率,降低了平均端到端时延,显著改善网络性能,增强了数据传输的实时性和可靠性.

Load awareness and pseudo gossip mechanism based high stability routing protocol

The establishment of flying ad hoc networks (FANETs) can effectively meet the networking communication requirements of UAV cluster operation, but compared with the traditional mobile ad hoc network, flying ad hoc network has the characteristics of faster node movement and dynamic network topology. To solve the problem of network performance degradation caused by frequent link disconnection, this paper proposes a high stability routing protocol based on load sensing and pseudo gossip mechanism. Network congestion and node mobility are two main factors affecting path stability. In order to solve the problem of network congestion, a pseudo rumor limited flooding mechanism based on node load prediction is proposed. In the process of initiating routing requests, the node forwarding probability is dynamically adjusted to balance the network load and reduce the control overhead. Aiming at the high mobility characteristics of UAV nodes, a joint measurement index of link stability is proposed based on the received packet signal power strength. Simulation results show that, compared with AODV protocol and other improved protocols, this protocol can effectively reduce the network control overhead, improve the packet delivery rate, reduce the average end-to-end delay, significantly improve the network performance, and enhance the real-time and reliability of data transmission.
