In a space-air-ground integrated network (SAGIN), managing resources for the growing
number of highly-dynamic and heterogeneous radios is a challenging task. Symbiotic
communication (SC) is a novel paradigm, which leverages the analogy of the natural
ecosystem in biology to create a radio ecosystem in wireless networks that achieves
cooperative service exchange and resource sharing, that is, service/resource trading,
among numerous radios. As a result, the potential of symbiotic communication can be …
