Paris Subway Pricing-based Link Selection in Air-Space-Ground Networks

The space-air-ground integrated network (SAGIN) network is known as an integrated system with triply sub-networks, namely the satellites layer, aerial layer, and terrestrial layer. The base stations in the terrestrial layer and the unmanned aerial vehicles (UAVs) in the aerial layer act as relays to provide satellites connection for the terrestrial users. In this paper, considering the different connected services have different quality of service (QoS) and cost different prices, we design the function for both terrestrial users and relays. To deal with the transmission path selection from an economical perspective, we employ the Paris Metro Pricing (PMP) model to study usage-based pricing for connected services under market competition to maximize relays' revenue and meet the QoS requirement of users. The simulations show how terrestrial users' value on usage and sensitivity to QoS influence the optimal price, revenue, and competition of relays.
