Power-Aware Resource Management

• Built energy-aware Linux/RK in iPAQ, modified voltage-scaling enabling XScale BRH board, BitsyX, and the next-generation space computer microprocessor, PowerPC RAD750.

• Designed practical energy-aware scheduling policies in heterogeneous platforms to provide real-time guarantees and nearly-optimally reduce consumed energy with much less overhead.

• Designed generic multi-granularity reservation scheme, a new flexible reservation paradigm for multimedia applications which have high variability in resource requirements.  

• Developed a generic energy-aware QoS manager which smartly balances task QoS levels with available system energy to maximize satisfaction/utility given by users, application developers and system administrators.

Linux/RK Resource-Kernel Real-Time Operating System

• Built generic multi-resource reservation model to enable cooperative real-time guarantees of multiple resources simultaneously.

• Designed and implemented a filesystem-independent real-time disk management in Linux. 

• Built a resource synchronization protocol for real-time reservations.

Task Modeling for Embedded Systems

• Designed, analyzed and modeled applications in the real-time domain on VxWorks

Experience on Networked Systems

• Implemented a simulation for Simple Routing Information Protocol (SRIP) between a subnet of routers

• Developed a broker-based distributed computing infrastructure in JAVA

• Porting VIC/VAT videoconference tool on Darwin: Customizable Resource Management for Value-Added Network Services (in the area of Active Networks)
