Abstract

In this paper, we propose a joint large-scale resource allocation and optimal multibeam design for satellite-enabled Internet-of-Things (IoT) networks. To overcome the long latency issue in satellite communications, a new gaming optimisation framework is proposed, which is solved in real-time scenario. Firstly, IoT devices are clustered using coalition game that is designed for considering simultaneously transmission time minimisation and channel gain maximisation. Then, bisection search which is very low-complexity procedure is used for maximising the network energy efficiency in closed-form power allocation. The numerical results prove that our method outperforms conventional approaches and is applicable to large-scale networks with real-time IoT scenario.
