在源节点(S)和目的节点(D)之间的无线多跳网络中，S通过多条路由同时冗余地向D发送相同的数据包的多路径路由，可以有效地利用路由分集来增强无线数据传输的可靠性。然而，当将多路径路由应用于大型机器人移动的工厂时，如果选择较近的多条路由，则它们同时被机器人阻塞的概率会变大，因此无法提高丢包率方面的可靠性。本文提出了一种多路径路由方法，该方法可以在不知道节点位置的情况下选择物理上距离较远的多条路由。该方法通过多目标最大化问题中的标量化来最大化由“路由之间的距离”和“路由质量”组成的度量，可以自适应地控制S和D之间所选路由的拓扑。
In a wireless multi-hop network between a source node (S) and a destination node (D), multipath routing in which S redundantly sends the same packets to D through multiple routes at the same time is effective for enhancing the reliability of the wireless data transmission by means of route diversity. However, when applying the multipath routing to a factory where huge robots are moving around, if closer multiple routes are selected, the probability that they are blocked by the robots at the same time becomes higher, so the reliability in terms of packet loss rate cannot be enhanced. This paper proposes a multipath routing method which can select physically distant multiple routes without any knowledge on the locations of nodes. Maximizing the metric composed of "the distance between routes" and "the route quality" by means of scalarization in multi-objective maximization problem, the proposed method can adaptively control the topologies of selected routes between S and D.
