FIELD: radio engineering, communication.
SUBSTANCE: control system uses a wireless mesh network to provide communication between a host computer and field devices. Performance of the wireless mesh network is monitored by collecting network performance data from each node, e.g. nodes with which it is communicating, received signal strengths over links to different nodes, the number of errors occurring on each link, and how frequently communication is occurring with each of the other nodes. A visual network map is generated using performance statistics based on the data gathered from the nodes of the wireless mesh network.
EFFECT: enabling diagnosis of potential problems in the network by estimating the probability of breakdown in the wireless network caused by loss of battery power on a separate node and making adjustments to improve network performance.
