Distributed deployment method for large-scale wireless sensor network testing and debugging

Abstract

The invention discloses a distributed deployment method for a large-scale wireless sensor network testing and debugging distributed deployment method. The method is suitable for the establishment of debugging and texting network of the wireless sensor network. The method comprises the following steps: the nodes to be tested in a wireless sensor network are connected with different adapter plates according to different interface modes, the adapter plates are utilized to ensure that the sensor nodes of different kinds and different operating systems are compatible; the nodes are all connected with debugging data collecting and processing gateways through USB ports, the collecting and processing gateways are connected with a control server through an Ethernet or a wireless network; and a time synchronization scheme is adopted to constitute a distributed deployment architecture. The number of the data collecting and processing gateways can be increased to realize the large-scale network extension; and the data collecting and processing gateways are connected to a center control server in same and peer-to-peer modes on the basis of TCP / IP, the data collecting and processing gateways can avoid mutual interference, so that the reality and accuracy of debugging data can be ensured.

Description

technical field [0001] The invention relates to a testing and debugging method of a wireless sensor network, in particular to deployment of testing and debugging of a large-scale wireless sensor network.

Services, counter-terrorism and disaster relief, and many othe...

AI Technical Summary

Problems solved by technology

When the network scale is small, the system needs to connect all target nodes to the debugging node one-to-one. When the network scale is large, only some target nodes can be connected to the debugging network, and the sensor network nodes cannot be collected and observed comprehensively. real-time data

In addition, the debugging network adopted by the system is wirelessly connected to the gateway node, and at the same time, it does not solve the time synchronization problem of the debugging node accessing the network. When facing large-scale deployment of sensor nodes, the authenticity and reliability of the debugging data be affected to a certain extent
