Energy profiling technique for network-level energy optimization

This work presents an energy profiling technique to optimize energy consumption in networks, with special focus in wireless sensor networks, where energy consumption is usually a major constraint. The approach aims to organize data obtained from power simulation in order to provide useful information to designers at high level abstraction layers, so that they are able to observe the impact of different design decisions, and therefore optimize their designs in terms of energy. Other energy profiling techniques deal only with local scope profiling, in order to optimize the node architecture. However, the energy profiling technique proposed here takes into account network-wide information expanding the scope of energy profiling to energy aware network design and optimization. Finally, the approach is further developed and its possibilities are explored by implementing on a wireless sensor network simulator and using it to optimize energy consumption at the network level in a pilot scenario.
