Method and device for controlling wireless sensor

Abstract

The invention provides a method and a device for controlling a wireless controller and aims to solve the problem that a wireless sensor network is built for specific application services and cannot be deployed in a large scope in the prior art. The method comprises the following steps of: acquiring sensing service data forwarded by a common access network from at least one wireless sensor; and performing related control over the sensing service data. When the scheme of the invention is adopted, a digital subscriber line access multiplexer (DSLAM) is provided with the functions of a sink node for serving sensor nodes with a wireless fidelity (WiFi) transmission function, so that a large-range sensor network is formed by connecting sensor nodes or local sensor networks at different positions through a telecommunication network; moreover, the sensor nodes or local sensor networks at different positions can supply acquired information to a great amount of different applications, so that a multi-service and multi-sensor service mode is realized.

Description

technical field [0001] The invention relates to a communication network, in particular to a control device in the communication network. Background technique [0002] Now, WLAN-based city wide wireless network (WLAN-based city wide wireless network) has been deployed in many cities in the world. According to the forecast, the number of wireless cities will reach 1500 in 2010. In China, many cities have also announced plans to establish wireless cities. The so-called wireless city is to provide communication services such as the Internet by establishing a wireless network covering the entire city. At present, WiFi (Wireless Fidelity, wireless high-fidelity) network technology is mainly used. Computers, smartphones and other terminals no longer need to be connected to network cables to achieve networking; in addition, wireless broadband networks have a wide coverage, not only limited to a room or a building, but like mobile phone signals, covering the entire urban area. Use...

AI Technical Summary

Problems solved by technology

Because the existing sensor networks all use Zigbee or bluetooth technology for networking, therefore, the physical coverage of the sensor network is small, for example, usually the existing wireless sensor network can only have dozens of sensor nodes; in addition, distributed The sensor networks in different geographical locations of the city are independent of each other and cannot be integrated into a large-scale sensor network

Therefore, so far, it is impossible to form a large-scale sensor network

In addition, network nodes in the telecommunication network, such as DSLAM, cannot distinguish whether the traffic is from ordinary terminals or from wireless sensor nodes. Therefore, it is impossible to perform QoS control for sensing services
