This paper investigates the edge caching in maritime wireless networks to cope with traffic surge issue in offshore region. A buoy equipped with wireless cache servers is introduced to provide wireless communication services for ships and users to relieve traffic load of onshore base station(OBS). Due to limited cache capacity and transmit power on the buoy, the transmission delay for ships and users can be increased. To tackle this problem, a joint cache placement and power allocation algorithm is proposed based on the Dinkelbach method and successive convex approximation. Simulation results show that the proposed algorithm can improve the cache hit rate with reducing the system cost.
