Scalable Emulation of TinyOS Applications in Heterogeneous Network Scenarios

Simulating the behavior of sensor applications in a heterogeneous network or under diverse environmental conditions is particularly challenging. In this paper, the authors present the design and implementation of TiQy, a scalable framework that allows unmodified TinyOS applications to be evaluated in a diverse set of operating conditions, including heterogeneous networks. They validate TiQ against MoteLab, a physical sensor network testbed, and show that TiQ can predict the behavior of the real network with less than 4% error.
