Abstract: In one embodiment, a reactive routing computer network may be partitioned into diverse logical topologies, and a source node may transmit route request (RREQ) messages toward a destination node on each logical topology. In response, the source node may receive route reply (RREP) messages indicating routes to the destination node in each logical topology. The source node may thus select a route for each logical topology to reach the destination node, accordingly. In another embodiment, if partitioned logical topologies do not produce two or more routes or as a standalone embodiment, the source node may transmit RREQ messages toward the destination node without any corresponding logical topology. The destination node receives RREQ messages, and two or more routes from the source node to the destination node may be determined (e.g., by the destination or source node) based on the received RREQ messages at the destination node and path selection criteria.

Abstract translation: 在一个实施例中，可以将反应性路由计算机网络划分为不同的逻辑拓扑，并且源节点可以向每个逻辑拓扑上的目的地节点发送路由请求（RREQ）消息。 作为响应，源节点可以在每个逻辑拓扑中接收指示到目的地节点的路由的路由回复（RREP）消息。 因此，源节点可以相应地为每个逻辑拓扑选择到达目的地节点的路由。 在另一个实施例中，如果分区逻辑拓扑不产生两个或更多个路由或者作为独立实施例，则源节点可以向目的地节点发送RREQ消息而没有任何对应的逻辑拓扑。 目的地节点接收RREQ消息，并且可以基于目的地节点处的接收到的RREQ消息和路径选择标准来确定（例如，目的地或源节点）从源节点到目的地节点的两条或更多路由。

Abstract: In one embodiment, a method comprises identifying an age of payload data in a data packet by a wireless network node configured for transmitting the data packet to a multi-hop destination via a wireless mesh network; determining by the wireless network node a schedule for the data packet reaching the multi-hop destination; and the wireless network node prioritizing queuing of the data packet for Collision Sense with Multiple Access and Collision Avoidance (CSMA-CA) based wireless transmission in the wireless mesh network based on the corresponding age, relative to the schedule and respective ages of other data packets awaiting transmission by the wireless network node to the destination, where a higher-aged data packet relative to the schedule is granted a higher priority than a lower-aged data packet relative to the schedule.
