Abstract:

In order to enhance system capability and reliability in diverse scenarios of smart grid traffic with different quality of service requirements, a cognitive technology of double path maintenance for wireless smart meters is proposed using causality tree. The causality tree performs efficient reasoning by using the underlying causal relationships between metrics and events which are defined in the program of smart meters. Path maintenance metrics identify routing design issues about link states, link qualities, and correlated dynamics transitions in terms of received signal strength indicator and packet reception rate. Physical experiments are used to evaluate the reliable performance of the wireless smart meters in the scenarios of channel and electromagnetic interference.

Key words: smart grid, wireless sensor networks, semantic metrics, machine to machine, quality of service
