NoSQL Database Abstraction for Wireless Ad-Hoc and Sensor Networks

Abstract

Database abstractions, such as TinyDB, TikiriDB and Cougar, have been used successfully in wireless sensor networks (WSN). These database abstractions 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 database abstraction for WASNs. In this research, we design, implement and experiment a NoSQL based database abstraction for WSN. The resulting NoSQL database abstraction can be directly configure and compiled with RedisDB NoSQL and run on top of Contiki environment. Comparing NoSQL database abstraction with traditional database abstraction such as TikiriDB and TinyDB, execution time of queries in NoSQL database abstraction is better than the other database abstractions.
