[en] In this paper, we investigate the multi-channel cooperative
spectrum sharing in hybrid satellite-terrestrial internet
of things (IoT) networks with the auction mechanism, which is
designed to reduce the operational expenditure of the satellitebased
IoT (S-IoT) network while alleviating the spectrum scarcity
issues of terrestrial-based IoT (T-IoT) network. The cluster
heads of selected T-IoT networks assist the primary satellite
users transmission through cooperative relaying techniques in
exchange for spectrum access. We propose an auction-based
optimization problem to maximize the sum transmission rate
of all primary S-IoT receivers with the appropriate secondary
network selection and corresponding radio resource allocation
profile by the distributed implementation while meeting the
minimum transmission rate of secondary receivers of each TIoT
network. Specifically, the one-shot Vickrey-Clarke-Groves
(VCG) auction is introduced to obtain the maximum social
welfare, where the winner determination problem is transformed
into an assignment problem and solved by the Hungarian algorithm.
To further reduce the primary satellite network decision
complexity, the sequential Vickrey auction is implemented by
sequential fashion until all channels are auctioned. Due to
incentive compatibility with those two auction mechanisms, the
secondary T-IoT cluster yields the true bids of each channel,
where both the non-orthogonal multiple access (NOMA) and time
division multiple access (TDMA) schemes are implemented in
cooperative communication. Finally, simulation results validate
the effectiveness and fairness of the proposed auction-based
approach as well as the superiority of the NOMA scheme in
secondary relays selection. Moreover, the influence of key factors
on the performance of the proposed scheme is analyzed in detail.
