NoSQL query processing system for wireless ad-hoc and sensor networks

TinyDB and TikiriDB are query processing systems, which have been used successfully in wireless sensor networks (WSN). These query processing systems provide a SQL query interface to extract data from sensors and it has proven to be a convenient programming interface in these environments. However, a relational database model that guarantees ACID properties is not a good match for a wireless sensor network since consistent connectivity or the uninterrupted operation of the sensor nodes cannot be expected. We noted that the NoSQL approach which does not rely on the ACID properties is a better match for a query processing systems for WASNs. We developed a NoSQL based query processing system on the Contiki operating system that is popular among the WSN community.
