Declarative interface for in-network actuation on wireless sensor-actuator networks
Asanka Sayakkara, M. D. J. S. Goonetillake, Kasun De Zoysa · 2012
Declarative SQL queries are a way of abstracting out the underlying complexity in Wireless sensor-actuator networks (WSAN). Current SQL syntax to perform actuation tasks misleads the user because of their artificial way of expressing the actuation tasks thus violating the purpose of the declarative nature. Particularly with respect to distributed in-network actuation tasks where multiple sensor nodes and actuator nodes are involved, the user may be required to write multiple queries based on the current actuation query syntax causing a negative impact on the performance. We address these issues in existing declarative layer with modifications to the virtual data table of the abstraction and thus a new syntax is suggested and implemented.
