基于位置信息的船舶编队自组网路由协议设计

Design of Ad-Hoc Network Protocol for Ship Formation Based on Location Information

随着技术不断发展,船舶编队协同是未来海上应用的主要方式。船舶编队因任务需求经常发生队形变换,船舶之间的相对位置也会发生变化,从而导致网络拓扑产生改变,为了保证船舶编队通信的可靠,设计一个有效感知编队拓扑状态变化的路由协议是非常重要的。因此论文提出了一种基于位置信息的船舶编队自组网路由协议(Location-based Rout⁃ing for Ship Formation,LRSF),通过交互节点之间的位置信息,预测节点之间的链路状态变化并定义链路质量,建立链路拓扑感知模型,链路质量作为权值在路由计算中寻找最可靠的路径。最后在Qualnet上进行实验,与OLSR进行比较,实验结果表明LRSF算法在分组投递率以及平均端到端时延等网络指标上,优于OLSR协议。

With the development of technology,ship formations are the primary means of future operations.Ship formations of⁃ten change shape due to mission requirements,and the relative positions between ships,ships and land also change,resulting in changes in network topology.In order to ensure the reliability of ship formation communication,it is very important to design a rout⁃ing protocol that effectively senses the changes of fleet topology.Therefore,a location-based routing for ship formation is proposed in this paper.It predicts the link state change through the location information between the nodes to define the link quality,and es⁃tablishes topology awareness model.Link quality is used as a weight to find the most reliable path in route calculation.Finally,ex⁃periments are carried out on Qualnet and compared with OLSR.The experimental results show that LRSF algorithm is superior to OL⁃SR in terms of packet delivery rate and average end-to-end delay.
