How do I get energy consumption over simulation time for each sensor in NetSim v11.1. The results window only gives the summary results, but I need to find the energy consumption over the simulation time.
Please see can look at https://tetcos.freshdesk.com/support/solutions/articles/14000088573-where-is-energy-consumption-battery-model-in-netsim-wsn-iot-set-calculated-
Can we use NetSim for doing energy harvesting / Green IoT projects as well?
Yes. There is are parameters in the NetSim for setting energy harvesting.
With regards to Green IoT, it depends on what it means. If its relates to lower power consumption, and energy harvesting then it can be simulated in NetSim.
There are many user contributed projects on energy consumption in the NetSim file exchange page - https://tetcos.com/file-exchange.html
The power source represents the source of energy. Each node has its own single source of power. The mainline power source is assumed to have infinite energy while batteries have limited initial energy. When energy harvesting is turned on, it replenishes the battery energy. If the power of a node is completely depleted the node can no longer operate.
The different currents used in the energy model calculations are:
TransmitCurrent
ReceiveCurrent
IdleModeCurrent
SleepModeCurrent
The energy consumed in each of these operations would be.
TransmitEnergy = TransmitCurrent * Voltage * Time (for which node transmits packets)
ReceiveEnergy = ReceiveCurrent * Voltage * Time (for which node receives packets)
IdleModeEnergy = IdleModeCurrent * Voltage * Time (in Idle mode)
SleepModeEnergy = SleepModeCurrent * Voltage * Time (in sleep mode)
TotalEnergy = TransmitEnergy + ReceiveEnergy +IdleModeEnergy + SleepModeEnergy
NetSim also has an Energy-Harvesting Model which is modeled as EnergyHarvested = RechargingCurrent * Voltage * Time
Hence, BatteryEnergy (at any time) = InitialEnergy - TotalEnergyConsumed + EnergyHarvested
I can see how to obtain the summary energy metrics, in NetSim.
What should I do to obtain data on energy consumption vs. time?
How can we compare the energy consumption during 'low traffic conditions' with that during 'high traffic conditions'?
To compare energy consumption in NetSim under varying traffic conditions — low and high you can refer to the article on plotting energy consumption over time: https://support.tetcos.com/support/solutions/articles/14000088652-how-do-i-plot-energy-consumption-over-time-for-sensor-nodes-for-wsn-iot-networks
After gathering data for both low and high traffic conditions, you can compare them to observe differences and analyze it. In version 14, they've added energy-related logs directly into the product. You can enable it, run simulations and check the energy log in a CSV file.
