异构接口多跳无线网络（Het-MuNets）正成为战术网络以及车辆通信、无线回程和非地面连接等轻基础设施应用的一种有前景的范式。为了利用异构通信技术在穿透性、干扰和带宽方面的多样化特性，必须在逐跳基础上确定数据包到接口的分配，这使得路由和调度变得高度复杂。在这项工作中，我们为具有多个并发流的Het-MuNets开发了一个用于联合数据包路由、链路调度和接口分配的统一框架。通过将数据包到接口的分配建模为虚拟子节点之间的传输，我们将接口分配转化为设备内虚拟路由，并在统一的多层最短路径偏置背压（SP-BP）方案下与物理路由和调度联合求解。数值结果表明，所提出的框架在吞吐量、延迟和数据包投递率方面优于在其他基线图模型上运行的SP-BP以及非背压路由方案。
英文摘要
Heterogeneous-interface multihop wireless networks (Het-MuNets) are emerging as a promising paradigm for tactical networks and for infrastructure-light applications such as vehicular communications, wireless backhaul, and non-terrestrial connectivity. To exploit the diverse profiles of heterogeneous communication technologies in penetration, interference, and bandwidth, packet-to-interface assignment must be determined on a per-hop basis, making routing and scheduling highly complex. In this work, we develop a unified framework for joint packet routing, link scheduling, and interface assignment in Het-MuNets with multiple concurrent flows. By modeling packet-to-interface assignment as transmission between virtual subnodes, we transform interface assignment into intra-device virtual routing, which is solved jointly with physical routing and scheduling under a unified multi-layer shortest path-biased Backpressure (SP-BP) scheme. Numerical results demonstrate that the proposed framework outperforms SP-BP operating on other baseline graph models and non-backpressure routing schemes in goodput, latency, and packet delivery rate.
