Heterogeneous Traffic Offloading in Space-Air-Ground Integrated Networks

While the 5-th generation of communication networks (5G) is taking its first deployment steps, high doubts still concern fulfilment stringent requirements slices. To meet these complex requirements, robust access should support current 5G air interface. In this regard, space and networks, namely satellites unmanned aerial vehicles (UAVs) are expected to play a key role due wide coverage flexible deployment, respectively. Currently, integration platforms in terrestrial weak though. Therefore, we suggest bridging gap by designing heterogeneous traffic offloading approach space-air-ground integrated network (SAGIN). Our innovative covers co-existing two slices smartly appropriate segment SAGIN. Specifically, ultra-reliable low-latency communications (URLLC) offloaded UAV link satisfy terms latency. However, enhanced mobile broadband (eMBB) link, satellite because it less sensitive delay but needs data rates. boosts network’s availability reduces latency experienced SAGIN through an efficient resource allocation optimized design UAVs trajectory. findings highlight that concrete between segments plays achieve better quality service (QoS) for different with requirements.
