Abstract

The invention relates to the technical field of information and communication, in particular to an organization mechanism of a centralized large-scale wireless sensing network and an implementation device. In the technical scheme, a sensing gateway controller realizes the functions of management, monitoring, dynamic configuration, control and the like of the large-scale wireless sensing network. A wireless sensing access point can be regarded as a lightweight sensing gateway; and data forwarding functions of a sensor and the sensing gateway controller and topology maintenance and management functions of the local wireless sensing network are realized under the control of the sensing gateway controller. The wireless sensing gateway controller uniformly configures and controls the wireless sensing access points in the wireless sensing network, and uniformly bridges, forwards and encrypts the traffic of the sensing network to enhance the manageability of the large-scale wireless sensing network. Therefore, efficient organization, centralized control and management of the large-scale wireless sensing network can be realized.

Description

technical field [0001] The invention relates to the field of information and communication technology, in particular to a novel centralized large-scale wireless sensor network organization mechanism and an implementation device. Background technique [0002] In recent years, wireless sensor network technology has been developed rapidly. However, 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. [0003] figure 1 A schematic diagram of a network topology structure in the prior art is shown. In the wireless sensor network, the sensor gateway is usually used to manage and control the sensor network, and realize the communication interface with the external network. The startup of a sensor gateway requires a lot of configuration work. For ...
