TinyDB2: Porting a query driven data extraction system to TinyOS2.x

Abstract

In query driven extraction of data from Wireless Sensor Network (WSNs), application developers can get readings from sensor nodes by using SQL like queries. In normal WSN applications, users need to program the application in WSN specific platform, which not only requires large programming efforts but also makes it difficult to change the application parameters once deployed. SQL like queries present much simplified approach of data collection and changing parameters of application on the air. In this paper, we study one of query driven system - TinyDB. TinyDB was used in TinyOS1.x but due to changes in architecture of TinyOS from TinyOS1.x to TinyOS2.x, TinyDB needed to be ported to newer version of TinyOS. This paper describes the architecture of newer TinyDB system, ported to work with TinyOS2.x, in detail and also presents the major porting changes that were required to make it compatible with TinyOS2.x. © 2011 Springer-Verlag.
