Integrated Concurrency and Energy Management (ICEM)

Device driver architecture that manages energy Implemented in TinyOS 2.0 Three driver classes: virtualized, shared, dedicated Power Locks: synchronization primitives which couple energy, configuration, and concurrency management. Component library: arbiters, power managers, and configurators. Advantages of ICEM Energy Efficient: within 1.6% of hand tuned implementation Reduces code complexity: 400 vs 68 lines (nesC)
