Big sensor-generated data streaming using Kafka and Impala for data storage in Wireless Sensor Network for CO2 monitoring

摘要

Wireless Sensor Network (WSN) is a system that have a capability to conduct data acquisition and monitoring in a wide sampling area for a long time. However, because of its big-scale monitoring, amount of data accumulated from WSN is very huge. Conventional database system may not be able to handle its big amount of data. To overcome that, big data approach is used for an alternative data storage system and data analysis process. This research developed a WSN system for CO2 monitoring using Kafka and Impala to distribute a huge amount of data. Sensor nodes gather data and accumulated in temporary storage then streamed via Kafka platform to be stored into Impala database. System tested with data gathered from our-own made sensor nodes and give a good performance.
