Message mining system and mining method for wireless sensor network based on association rules

Abstract

The invention discloses a wireless sensor network message mining system and mining method based on association rules. The mining system comprises an industrial computer, a wireless sensor network monitor and a wireless sensor network node network, wherein the wireless sensor network monitor is in network connection with the industrial computer, and is located in the wireless sensor network node network. The message mining method solves the problems that in the distributed network, errors which occur not frequently are produced due to complex interaction among nodes and are difficult to locate. Problematic sequences existing in message sequences are found according to the improved data mining method based on the association rules, and errors difficult to find in debugging of the wireless sensor network can be found. The wireless sensor network message mining system and mining method based on the association rules can be well used for protocol improvement and debugging of the wireless sensor network, and have wide application value.

Problems solved by technology

[0004] Unfortunately, for wireless sensor networks, application errors are often not caused by coding errors at a single point, but by incorrect interactions between different sensor nodes.

Possible reasons for this type of interaction include: 1. Design flaws in the wireless sensor network protocol (losing the handling of some boundary events, making the protocol unable to handle these events correctly) 2. Unforeseen artificial node interaction event

At the same time, these interactive errors are not reproducible, because repeating the same experimental steps does not necessarily lead to the same boundary conditions

At the same time, due to the Ad-hoc multi-hop working structure in the wireless sensor network, it is difficult for the outside to observe the internal interaction and structure of the wireless sensor network. For such errors, it is more obvious to locate and eliminate errors under code-level debugging. difficulty
