Towards Declarative Query Scoping in Sensor Networks

Abstract. In the last decade, several large-scale wireless sensor networks have been deployed to monitor a variety of environments. The declarative nature of the database approach for accessing sensor data has gained great popularity because of both its simplicity and its energyefficient implementation. At the same time another declarative abstraction made its way into mainstream sensor network deployments: userdefined groups of nodes. By restricting the set of nodes that participate in a task to such a group, the overall network lifetime can be prolonged. It is straightforward to see that integrating these two approaches, that is, restricting a query’s scope to a group of sensor nodes, is beneficial. In this work we explore the integration of two such database and scoping technologies: TikiDB, a modern reincarnation of a sensor network query processor, and Scopes, a network-wide grouping mechanism.
