Sensor networking message routing method based on tasks

Abstract

The invention discloses a sensor networking message routing method based on tasks, which belongs to the technical field of sensor networking application, and comprises the following steps: S1, establishing a default routing network, a static routing network and a dynamic routing network; S2, when the data are distributed, the priority of routing addressing being sequentially decreased according to a static routing network, a dynamic routing network and a default routing network; and S3, generating a routing link path, and completing data sending, wherein the default routing network is constructed according to an information intercommunication relationship among all nodes; the static routing network is constructed according to the requirement of the collaborative task and the physical link condition between the collaborative nodes; and the dynamic path is dynamically constructed according to the network link state of the static routing network so as to meet the message routing requirements in various physical link environments, and meanwhile, the message routing relationship between the sensors can be flexibly adjusted according to tasks so as to realize the purpose of efficient message routing forwarding.

Description

technical field [0001] The invention belongs to the technical field of sensor networking applications, and in particular relates to a task-based sensor networking message routing method. Background technique [0002] Most of the existing sensor networks are based on TCP / IP networks such as Ethernet, WIFI, and 4G. The routing of messages is completed directly through network devices such as routers and switches, without special processing by sensor devices. However, this method cannot be applied to non-IP networks such as dedicated data transmission, microwave scattering communication, and satellite communication. In some wired networks where internal and external networks are isolated, general-purpose information routing and switching equipment still cannot work effectively. [0003] The existing sensor information reporting method usually adopts a tree-like layer-by-layer collection method, and the upper-level nodes fuse and process the collected data of the lower-level nod...

However, this method cannot be applied to non-IP networks such as dedicated data transmission, microwave scattering communication, and satellite communication. In some wired networks with internal and external network isolation, general-purpose information routing and switching equipment still cannot work effectively

[0003] The existing sensor information reporting method usually adopts a tree-like layer-by-layer collection method. The upper-level nodes fuse and process the collected data of the lower-level nodes. After layer-by-layer processing, a lot of detailed information is lost.

At the same time, due to the difference in the upper management nodes to which the sensors belong, it becomes very difficult for adjacent sensors to work collaboratively, and the exchange efficiency of collaborative information is also very low.
