Embodiment Construction
[0029] The traditional wireless sensor network is a three-layer architecture, such as image 3 As shown, it includes perception layer, information aggregation layer and data center. The sensing layer includes at least one sensor node. The specific number is determined according to the needs of the environment. The sensor nodes take into account the dual functions of sensing information and relay transmission. The closer the sensor is to the information convergence layer, the heavier the task of relay transmission is, and the sensing information is sent to the information network. Convergence layer. The information aggregation layer includes at least one aggregation node, the specific number is determined according to the needs, and the aggregation node realizes the collaborative processing, fusion and return of the perception data. The data center receives the data information from the information aggregation layer, and makes corresponding processing on the data information, ...

The invention discloses a wireless sensor network positioning system. The system comprises a sensing layer, an information gathering layer, a data center and a communication support half layer; the communication support half layer is used for sending the information from the sensing layer to the information gathering layer and executing a relay communication task. By adopting the system provided by the invention, the invention has the beneficial effects that the communication support half layer is added between the sensing layer and the information gathering layer, the relay communication task is carried out by the dedicated communication support half layer, so that the function of communication support to the overall network is realized, and the electricity consumed by the sensor of the sensing layer to carry out the relay communication task is reduced, thereby prolonging the service life of the sensor of the sensing layer, and further prolonging the service life of the overall wireless sensor network, and enhancing the stability of the network. In order to ensure the low cost and simple scheme, the communication support node of the communication support half layer can adopt common anchoring nodes with enhanced communication capability, wherein the enhancement of the communication capability includes adopting batteries with larger volumes and the like.
Description
technical field [0001] The invention relates to the field of wireless communication, more specifically, to a wireless sensor network positioning system. Background technique [0002] The life cycle of a wireless sensor network: that is, the duration from the start of the network to the time when the required information cannot be provided for the observer. [0003] The wireless sensor network is composed of a large number of cheap micro-sensor nodes deployed in the monitoring area, and forms a multi-hop self-organizing network system through wireless communication. information and send it to observers. [0004] A sensor network usually includes sensor nodes and sink nodes. The sensor nodes are tiny and powered by batteries that carry limited energy. Each sensor node takes into account the dual functions of a terminal and a router of a traditional network node. In addition to performing local information perception and data processing, it also needs to store, manage, and i...
