Remote Energy Monitoring System by Cellular Network

SUMMARY Recently, improvement in power saving and cost efficiency by monitoring the operation status of various facilities over the network has gained attention. A wireless network, especially a cellular network, has advantages in mobility, coverage, and scalability. On the other hand, it has the disadvantage of low reliability, due to rapid changes in the available bandwidth. We propose a transmission control scheme based on data priority and instantaneous available bandwidth to realize a highly reliable remote monitoring system via a cellular network. We have developed our proposed monitoring system and evaluated the effectiveness of our scheme, and proved it reduces the maximum transmission delay of sensor status to 1/10 compared to best-effort transmission. © 2013 Wiley Periodicals, Inc.
