Keynotes: Data mining and machine learning applications in MMOs

Summary form only given. Database abstractions, such as TinyDB [1] and TikiriDB [2], have been used successfully in wireless sensor networks (WSN). These abstractions provide an interface for SQL like queries to extract data from sensors. This has proven to be a convenient programming interface in these environments. However, a relational database model that guarantees ACID (Atomicity, Consistency, Isolation, and Durability) properties is not a good option 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 database abstraction for WSNs. We also noted that this idea can be extended to wireless ad hoc networks in general and implemented a NoSQL based database abstraction for smartphones which uses Android operating system.
