Summary

This article deals with Energy Consumption of Networked Embedded Systems.

Due to the increase of utilization of connected devices, we need to focus on the energy consumption of these connections. Indeed, the Internet of Things allows us to connect our devices to the traditional Internet but the problem is that the protocols we use to do so were made without taking care of energy-efficiency, so these protocols are sometimes not adapted to the software we use.

The first important thing explained by the authors is that of the energy consumption is caused by the radio transceiver.

Authors also explain that there is an energy measurement methodology and there are different categories of measurement and estimation methods according to the device you are using.

Authors then explain the relation between energy consumption and internet protocols like IP, TCP or MAC and then explain the methodology developed in the article. If you use low-power wireless devices, it is difficult to mesaure the energy consumption, so you can only estimate it. They try to explain step by step the process which is based on the use of two energy estimation techniques, by using this method, we want to quantify the differences between simulation-based and real world software-based methods.
