Abstract

The invention relates to the technical field of information and communications, in particular to a method for discovering a ubiquitous sensor network controller in a centralized control wireless sensor network. A novel architecture and networking equipment of the centralized control wireless sensor network are designed to solve the problems of controllability and manageability of the large-scale wireless sensor networks. In the networking architecture, the ubiquitous sensor network controller realizes the functions such as management, monitoring, dynamic configuration, control and the like of the whole wireless sensor network. Wireless sensor access multiplexing equipment is controlled by the ubiquitous sensor network controller to realize topology maintenance and management control of local wireless sensor networks. By adopting the method, the wireless sensor access multiplexing equipment is helped to automatically discover the available ubiquitous sensor network controllers in the network and select the best ubiquitous sensor network controller to establish network connection, thus being part of wireless sensor network topology controlled by the ubiquitous sensor network controller.

Description

technical field [0001] The invention relates to a communication network, in particular to a method for discovering a ubiquitous sensor network controller in a centralized control wireless sensor network. Background technique [0002] 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 a large-scale sensor network, it is usually necessary to deploy a large number of sensor gateways, and each sensor gateway needs to be dynamically managed, monitored and controlled. For a large-scale sensor network containing hundreds or even thousands of sensor gateways, the burden of network management will be very heavy. In terms of service management, in order to achieve better service performance, it is necessary to carry out dynamic coordination in the whole network, but because the sensor ga...

AI Technical Summary

Problems solved by technology

In terms of service management, in order to achieve better service performance, it is necessary to carry out dynamic coordination in the whole network, but because the sensor gateway is relatively independent, it is very difficult to achieve this

In terms of security, due to coverage requirements, sensor gateways are often installed in places where security cannot be guaranteed. If the sensor gateway is stolen, the configuration information statically stored in the sensor gateway will become a leak channel

At the same time, how to prevent illegal sensor gateway access also poses a challenge to the security of sensor networks.

At present, there is no suitable solution to the problems encountered in the development of these small-scale wireless sensor networks to large-scale wireless sensor networks.
