Abstract

The invention discloses a route selection method and device and a gateway, applied to the wireless sensor Mesh network. The route selection method comprises that an integrated route quality value of all routing nodes in multiple transmission routes of each node is calculated according to the value and weight of a target parameter, and the target parameter is a parameter related to route selection of the wireless sensor Mesh network; a selected route is obtained from the multiple transmission routes according to the integrated route quality value; and when it is determined that the selected route is different from a preset route in a routing table of the node, the selected route is sent to the node so that the node updates the routing table according to the selected route, and data is transmitted according to the updated routing table. According to the invention, the integrated route quality of all the routing nodes of each node serves as basis of route selection, influence of complex and changeable real environment on the network is taken into full consideration, and the validity and stability of the network are ensured.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a routing selection method, device and gateway. Background technique [0002] The wireless sensor Mesh network is a wireless network composed of multiple stationary or moving sensors in a self-organizing and multi-hop manner. The sensors can perceive, collect, process and transmit the data of the perceived environmental objects in the geographical area covered by the network, and finally These data are sent to the owner of the network, which is widely used in military, intelligent transportation, environmental monitoring, medical and health and other fields. [0003] figure 1 It is a schematic diagram of the network topology of the wireless sensor Mesh network in the prior art, such as figure 1 As shown, the gateway 3 and the Mesh routing node 4 constitute the backbone layer of the wireless sensor Mesh network. The Mesh routing node 4 is connected to four sensors ...
