Abstract
Wireless sensor network testbeds are important elements of sensor network/IoT research. The Indriya testbed has been serving the sensor network community for the last 8 years. Researchers from more than a hundred institutions around the world have been actively using the testbed in their work. However, given that Indriya has been deployed for over 8 years, it has a number of limitations. For example, it lacks support for heterogeneous devices and the ability to handle data generated by the testbed with no loss, even at a relatively low sampling rate. In this paper, we present the design and implementation of an upgraded version of Indriya, Indriya2, with the following improvements, namely (1) support for heterogeneous sensor devices, (2) support for higher data rate through the infrastructure, (3) support for multiple users to schedule jobs over non-overlapping set of heterogeneous nodes at the same time, and (4) a real-time publish/subscribe architecture to send/receive data to/from the testbed nodes.
