Abstract

The invention provides a communication maintenance scheme matching method, a link monitor and a wireless sensor network. The communication maintenance scheme matching method comprises the following steps of: detecting the communication quality of a single-hop communication link; carrying out statistics and analysis on the communication quality, and obtaining the packet loss of the single-hop communication link; and comparing the packet loss with the preset packet loss threshold, respectively matching the respective corresponding optimum communication maintenance scheme for each communication stage in the single-hop communication link according to the comparison results. Compared with the prior art, the communication maintenance scheme matching method, the link monitor and the wireless sensor network provided by the invention have the advantages that the communication quality of the single-hop communication link can be detected and analyzed in real time, and the self corresponding optimum communication maintenance scheme is matched for each communication stage in the single-hop communication link, so the communication resource utilization rate is improved, the time characteristics and the space characteristics in the communication process can be met in real time, the reliability is further improved, and the high-reliability requirement is met.

Description

technical field [0001] The present application relates to the technical field of wireless sensor networks, in particular to a communication maintenance scheme matching method, a link monitor and a wireless sensor network. Background technique [0002] With the in-depth development of the Internet of Things technology, wireless sensor networks have been widely used in various fields such as industrial control and military reconnaissance. Among them, the wireless sensor network uses electromagnetic waves as the carrier to transmit information in space, and it does not require wiring, which greatly reduces the cost of using the network. [0003] However, when the wireless sensor network uses electromagnetic waves as the carrier to transmit information, it is easily disturbed by the outside world. For example, with the increasing popularity of Bluetooth and WIFI (wireless fidelity, wireless fidelity) technology, the frequency of use of the 2.4G frequency band is getting higher ...
