Embodiment Construction

[0017] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] Such as figure 2 As shown, the centralized traffic forwarding method for centralized wireless sensor networks requires that all control and data traffic be transmitted through DTLS tunnels between wireless sensor access points and sensor gateway controllers, and all data traffic be transmitted between sensor gateway controllers Aggregation, processing and forwarding. The sensor gateway controller is the only data forwarding interface between the wireless sensor network and the external network.

[0019] Such as image 3 As shown, the local traffic forwarding method of centralized wireless sensor network divides the traffic of wireless sensor network into data flow and control flow, and adopts different forwarding processing methods for different types of traffic. The sensor network control traffic carries the control signaling ...

Abstract

The invention relates to the technical field of information and communications and provides a local flow forwarding method of a centralized wireless sensor network. In the technical scheme adopted by the invention, the flow of the wireless sensor network is classified into data flow and control flow; the control flow of the sensor network carries the control signaling of the wireless sensor network; the data flow of the sensor network carries the monitoring information acquired by a sensor; all the control flow of the sensor network is conveyed via a DTLS (datagram transport layer security) tunnel between a wireless sensor access point and a sensor gateway controller; and the data flow of the sensor network is directly forwarded by the wireless sensor access point locally, without being firstly conveyed to the sensor gateway controller via the tunnel. By utilizing the method provided by the invention, the large-scale wireless sensor network can have convenience in centralized control and solve the problem of transmission bottleneck.

Description

technical field [0001] The invention relates to the field of information and communication technologies, in particular to a traffic forwarding method and an implementation device of a wireless sensor network. Background technique [0002] In recent years, wireless sensor network technology has been developed rapidly, but the scale of wireless sensor networks currently deployed is generally small. With the gradual promotion of ubiquitous sensor network services, the establishment and use of large-scale wireless sensor networks will be an important trend in the next development of wireless sensor networks. In order to establish a large-scale wireless sensor network, the idea of ​​centralized wireless sensor network networking is proposed. Such as figure 1 As shown, in a centralized wireless sensor network, the sensor gateway controller acts as a centralized control device in the wireless sensor network, which is responsible for the management and control of the entire wirele...
