Due to the reliance on battery, energy consumption of WSNs has always been the most significant concern. In this work, a method which involves the design of a transaction / system-level based SystemC simulation environment for WSNs energy exploration, and the building of a hardware platform for the real world testbed node measurements to calibrate simulation, is therefore employed to guarantee the accuracy of the energy evaluation on WSNs. To accelerate and optimize the evaluation process, a genetic algorithm (GA) based optimization framework is implemented by MATLAB. The optimization...
