Analysis of UAV wireless network coverage and handover performance by Bonan YIN, Mugen PENG, Chenxi LIU

“…For the characteristics of unmanned aerial vehicle (UAV),such as high mobility,adjustable height,and high probability of line-of-sight channels,which introduced multiple challenges to the design and deployment of current and future wireless network,and the networking performance of UAV was the focus and difficult issues in the industry,the network coverage and handoff performance of heterogeneous UAV wireless network was analyzed,which provided insights into UAV wireless networking.Specifically,considering the outdated channel state information introduced by the UAV’s mobility,analytical expressions of handover probability,handover error probability,and coverage probability for heterogeneous UAV wireless network were derived by utilizing the tools from stochastic geometry.In addition,the impacts of the UAV’s mobility,height,as well as the density of terrestrial base stations on the aforementioned performance metrics were investigated.It shows that the outdated channel state information caused handover error,which increases first and then decreases with the increase of UAV’s moving speed and density of base stations.Meanwhile,the impact of UAV’s flight height on coverage probability is more significant than that of moving speed.…”

Analysis on the coverage performance and networking scheme of an MEO constellation by Yanbin ZHAO, Renning WANG, Peipei HU

“…Geostationary earth orbit (GEO) satellite orbit position resources have been scarce for a long time.The development of giant low-orbit satellite constellations has made the low-orbit resources unprecedentedly scarce.As a compromise between GEO and low earth orbit (LEO) constellations, the medium earth orbit (MEO) constellation will surely become a battle field for all countries.Referring to various MEO constellations in the world and our national conditions, a (6+4) MEO constellation was proposed.STK (Satellite Tool Kit) was used to simulate and analyze the constellation coverage performance, inter-satellite link characteristics, gateway site selection and coverage performance.Inter-orbit communication was realized through ground station relay, effectively avoiding various problems through inter-satellite links.The system was more simple and steady.It's much valuable in strategy in the circumstance of global low-orbit resources scarce.…”
