低空多无人机自组网数据可靠传输的跨层方法
Cross-layer Method for Reliable Data Transmission in Low-altitudeUAVs Ad Hoc Network
摘要
Abstract
As the information transmission is sheltered easily by landform and terrain for the low-altitude Unmanned Aerial Vehicles(UAV) Ad Hoc networks,communication is interrupted frequent.Furthermore,the traditional congestion handling system cannot meet the quality requirement of UAV communication.In order to solve the above questions,a cross-layer method for reliable data transmission is proposed.The interruption probability of three communication mode is calculated based on channel conditions in the physical layer.The mechanism of the congestion degree division,according to the MAC layer information shared,based on the time that the packets enter in the buffering queue.The size of sliding windows is controlled by congestion in the transport layer,which can adaptively control the packet transmission rate of UAV.The best routing for reliable information transmission is selected by optimizing interruption probability and congestion degree in the network layer.Simulation results show,compared with Congestion Aware Routing protocol for Mobile(CARM) Ad Hoc network and Dynamic Congestion Aware Routing(DCAR) protocol,this method reduces interruption probability validly,and with the increase of information transmission rate and the speed of UAV,the low-altitude UAVs Ad Hoc networks get higher packet delivery ratio and lower average delay.关键词
