Duty Cycle Based Energy Management Tool for Wireless Sensor Networks

Wireless Sensor Networks are a valuable technology to support many applications, including smart cities and Internet of Things. Energy is a key resource for these devices, since they are usually battery operated. We propose a duty cycle based energy management tool that enables a better control of the duty cycle period according to the node energy availability, thus increasing the network lifetime. We present three different scenarios with three different configurations to show in what conditions the tool gets the best results. The tool was programmed for ContikiOS and the simulations were conducted with Cooja Simulator.
