Abstract

The embodiment of the invention discloses a method, a device and a system for route selection, and relates to the field of communication. The method for the route selection comprises the following steps of: acquiring mobile information of a neighbor node; and performing the route selection according to the mobile information of the neighbor node. The technical scheme provided by the embodiment of the invention is that a stable neighbor node is selected as a next hop node to forwarding a message by acquiring the mobile information of the neighbor node so as to reduce the lose of the message and improve the reliability for transmitting an AD hoc network message.

Description

technical field [0001] The present invention relates to the communication field, in particular to a routing method, device and system. Background technique [0002] Ad Hoc network is an autonomous wireless multi-hop network. Nodes in the network are mobile and can communicate with other nodes in any topology. When the network is transmitting data, some nodes in the network will leave or join the network. At this time, in the process of forwarding the message, the current node performs routing selection on neighbor nodes, and selects a next-hop node for forwarding the message from the neighbor nodes. According to the selection result, the current node forwards the message to the next-hop node. If the next-hop node has left the network, the message to the next-hop node will be lost. Therefore, the existing routing method is unstable, which affects the reliability of packet transmission. Contents of the invention [0003] The routing selection method, device and system p...
