摘要
With the rapid development of marine activities,there has been an increasing use of Internet-of-Things(IoT)devices for maritime applications.This leads to a growing demand for high-speed and ultra-reliable maritime communications.Current maritime communication networks(MCNs)mainly rely on marine satellites and on-shore base stations(BSs).The former generally provides limited transmission rate while the latter lacks wide-area coverage capability.As a result,state-of-the-art MCN lags far behind the terrestrial fifth-generation(5G)network.
