Embodiment Construction

[0058] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0059] The invention provides a system and method for data distribution in a wireless sensor network, which can reduce the amount of messages sent in the network, distribute the most accurate data for target observation in the network, and keep the data of each node in the network consistent , for data distribution of wireless, distributed sensor networks, so as to realize remote monitoring and tracking of vehicles, traffic, people or natural environments.

[0060] figure 2 It is a system structure diagram of the present invention, which is used for data distribution in the wireless sensor network. The system includes various nodes connected through a wireless network, and each node includes a sensing unit, a data cache and management unit, and a message control and sending and receiving unit connected successively. Wherein, the data...

Abstract

The invention discloses a system and a method for the data distribution in a wireless sensor network, and relates to the field of remote monitoring and tracing. The invention is invented to reduce the dispatching volume of the information in the wireless sensor network and ensure the most accurate data to be finally distributed to the whole network. When a node not only needs to transmit the data transmitted by the adjacent nodes, but also needs to send out the data thereof, all data to be sent out get together to generate a new data packet and intermediate data, so as to be sent out to all adjacent nodes, thereby only needing once sending of data broadcasting information and data information, and greatly reducing the dispatching volume of the information in the wireless sensor network. Under the condition that the intermediate data of the node which receives the data broadcasting information is as same as that of the data broadcasting information, the most accurate data can be finally distributed to the whole network is ensured through receiving the data which has the maximum signal strength. The invention is applied to the data distribution in the wireless and distributed sensor network.

Description

technical field [0001] The invention relates to the field of remote monitoring and tracking, in particular to a data distribution system and method in a wireless sensor network. Background technique [0002] Wireless sensor network is a powerful tool for monitoring the remote environment. It has many unique advantages such as low cost, low power consumption, and multi-function, so it can be widely used in many different fields. For example, in the military, it can realize real-time battlefield monitoring and battlefield loss. Evaluation, etc.; in business, it can realize smart home; in medical treatment, it can remotely monitor the patient's physical condition in real time, and can provide immediate assistance in case of emergency; in terms of environment, it can realize ecological environment monitoring, biodiversity Monitoring and other functions. [0003] figure 1 It is a structure diagram of a typical wireless sensor network. A large number of sensor nodes are arrange...
