针对海上业务传输需求的多样性以及海上多无线信道传输能力的差异化，提出一种面向业务特性的海上多无线信道资源传输调度算法。对于待传输的业务数据，首先，采用业务感知技术识别业务的带宽、时延、可靠性等业务传输需求，并根据全网拓扑结构、点到点链路质量计算得到发送方至接收方的各条端到端传输路径的传输能力值；然后，采用多网优选、多网组合、多网并发、确认重传等多无线信道传输模型，并结合各端到端传输路径，得到所有可能的候选传输策略及其对应的综合带宽、时延、误码率等综合传输能力值；最后，根据业务传输需求和各候选传输策略的综合传输能力值，加权得到各候选传输策略的业务传输服务质量值，并选择使得业务传输服务质量值最大的候选传输策略为最优的传输策略进行数据发送，从而实现业务传输需求与端到端传输路径能力的最佳匹配。仿真结果表明，该算法可根据海上各种不同业务的传输需求自适应选择最优的传输策略，有效提升了海上多无线信道环境下的业务传输效率。
According to the diversity of the transmission requirements and the capabilities differentiation of wireless channel in maritime, a new multi wireless channel resource transmission scheduling algorithm based on business characteristics is proposed. For the business data to be transmitted, the business perception technology is first used to identify the business transmission requirements such as bandwidth, delay and reliability, and the transmission capability values of each end-to-end transmission path from the sender to the receiver are calculated based on the network topology and point-point quality. Then multiple wireless channel transmission models such as multi-network preference, multi-network combination, multi-network concurrency, and acknowledgment retransmission are used in combination with end-to-end transmission path to obtain all possible candidate transmission strategies and their corresponding integrated transmission capability values such as bandwidth, delay and bit error rate. Finally, the business transmission service quality value of each candidate transmission strategy is weighted according to the business transmission requirements and the integrated transmission capability value of candidate transmission strategy, and the candidate transmission strategy with the highest business transmission service quality value is selected as the optimal transmission strategy, thus achieving the best between the business transmission requirements and the end-to-end transmission path capabilities. The simulation results show that the algorithm can adaptively select the optimal transmission strategy based on business characteristics, effectively improving the efficiency of business transmission in the maritime multi wireless channels environment.
