Rajkumar's interests lie in all aspects of embedded real-time systems and wireless/sensor networks.


My research interests lie in all aspects of embedded real-time systems and wireless/sensor networks. In the domain of embedded real-time systems, my interests include but are not limited to operating systems, scheduling theory, resource management, wired/wireless networking protocols, quality of service management, hardware/software architecture, model-based design tools and power management. In the context of wireless/sensor networks, my research interests span hardware, devices, power-efficient networking protocols, run-time environments, large-scale system architectures, visualization and administrative tools.


Rajkumar's work with self-driving vehicles is featured in this story from CBS Evening News (Oct. 13, 2013).
