摘要: 针对目前海洋空域中的航空自组网存在节点密度较小、连通概率较低的状况,提出了一种容延容断网络(DTN)的存储运载转发策略.从理论上分别推导出航空自组网中单、双向航路连通概率的数学表达式,并通过仿真实验验证了理论计算结果的正确性.进一步根据东亚和北美地区之间的实际航班数据仿真计算了北太平洋航路上航空自组网的连通概率.通过具体实例,分析了存储运载转发策略的有效性.结果表明,在航空自组网中,针对航班密度小的情况,采用该策略可以显著提高网络连通性.

Abstract: A scheme of storecarryforward in delay/disruption tolerant network (DTN) was introduced to eliminate some problems in the oceanic aeronautical Ad hoc networks (AANET), such as low node density and low connectivity. The connectivity probability of AANET on one and twoway of the flight routes were analyzed theoretically and verified through simulations. Furthermore, the connectivity probability of AANET over North Pacific Ocean Route was calculated using the information of scheduled flights between East Asia and North America, validating the effectiveness of the storecarryforward scheme. The result shows that the scheme can improve the connectivity of AANET, especially in the condition of low aircraft density.

Key words: aeronautical Ad hoc network, connectivity, aircraft, delay/disruption tolerant network, storecarryforward
