Abstract
In recent years, with the rapid development of maritime activities, the demand for high-speed, reliable, low-latency, and full-coverage marine communication network (MCN) has become increasingly urgent. At present, maritime communication services are mainly provided by satellite networks, but suffers from many limitations, such as surge of data volume, complex communication environment, uneven distribution of traffic and user density and different requirements for maritime services. In order to solve these problems, mobile edge computing (MEC), space-air-ground-sea integrated network (SAGSIN), and blockchain are considered to be promising technologies for MCN enhancement. In this paper, the challenges faced by MCN are discussed, and the above three technologies are applied to solve these challenges. Finally, a space-air-ground integrated network (SAGIN) assisted MCN architecture based on edge computing is proposed, and the future research directions are also put forward.
