To implement efficient computation offloading for secure maritime edge networks, a voyage-based computation offloading mechanism is proposed for compute-intensive applications at sea. The edge nodes for computation offloading and the base stations for maritime communication are deployed on vessels to dynamically provide mobile edge computing services for nearby users. On the large time scale, a Hopcroft-Karp based offloading algorithm is proposed to pre-calculate the best computation offloading scheme for multi-users with the voyage information. On the small time scale, whether to perform the pre-calculated offloading or the local computing can be determined by the real-time demand for computing resources of each user. Simulation results with real ship data show that the proposed voyage-based offloading method can effectively improve the delay, energy consumption, and traffic cost of the offloading tasks in maritime edge networks.
