Abstract
Recently, the research of the internet of vessels system is a hotspot in the marine engineering area. In this article, the Internet of Vessels based on Beidou satellite navigation system (IoV-BDS) architecture is proposed for marine cold chain transportation monitoring and scheduling. An improved communication method using Beidou short-message communication (SMC) is designed to ensure the reliability of ship-shore data transmission. Additionally, based on the IoV-BDS, we proposed a novel route scheduling optimization model which considers the key costs for marine cold chain transportation, such as fuel, catches damage, and refrigeration energy consumption, and designed a speed selection mechanism. Furthermore, an improved ant colony optimization (IACO) algorithm was utilized to optimize the whole fleet transportation routes, which takes advantage of the A-star algorithm to speed up the convergence of ant colony algorithm (ACO), a novel state transition rule was used to prevent falling into a locally optimal solution. The applicability of IoV-BDS was verified by the shipboard data acquisition and Beidou SMC experiments. The performance evaluation and analysis of route optimization schemes were presented by simulations and comparison with other schemes. The results demonstrated the benefit of our proposed schemes, in terms of solution quality and convergence of the algorithm.

Summary
With the development of information technology and the popularization of mobile terminals, modern society is gradually entering the ‘‘Internet of Things (IoT) era’’. As the IoV system is essential for marine cold chain transportation monitoring and route scheduling optimization. The following requirements should be met: reliable communication, real-time monitoring, route scheduling optimization, reducing transportation cost. Aim at the application scenarios, the monitoring data of ships need to be transmitted to shore-based center, and used to calculate and generate optimal scheduling information for each ship. Z. Zhang et al.: Marine Cold Chain Transportation Monitoring and Route Scheduling Optimization Based on IoV-BDS (SMC) is designed to ensure reliable ship-shore data transmission and efficient use of bandwidth.
