Discrete Event Simulation Framework for Power Aware Wireless Sensor Networks

The PAWiS (power aware wireless sensors) simulation framework facilitates design and simulation of wireless sensor network models. Main focus is given to power efficiency and therefore on capturing inefficiencies in various aspect of the system. These aspects include all layers of the communication system, the targeted class of application itself, the power supply and energy management, the central processing unit (CPU) and the sensor-actuator interface. The proposed simulation framework is based on the OMNeT++ discrete event simulator and provides PAWiS specific features (e.g. a mechanism to handle RF channel transmissions) to simulate, analyze and optimize the aforementioned aspects.
