How to add RF energy harvesting to a sensor?

I am using leach protocol and want to add capability of RF energy harvesting to each sesnor node. In NS3, just some line of codes are used to add the RF energy harvesting capability to each node. Deos there is any code that add RF EH to sensor?

Hi Hassan, Here is a simplified example of how you can integrate RF energy harvesting capabilities into sensor nodes using NS3: `

// Include necessary headers

#include "ns3/energy-harvester-module.h"

// Create an EnergyHarvester object for RF energy harvesting Ptr<EnergyHarvester> rfHarvester = CreateObject<RfEnergyHarvester> ();

// Attach the EnergyHarvester object to each sensor node

for (uint32_t i = 0; i < numNodes; ++i) { Ptr<Node> node = NodeList::GetNode(i); Ptr<BasicEnergySource> basicSource = CreateObject<BasicEnergySource> ();

basicSource->SetEnergyHarvester(rfHarvester);

node->AggregateObject(basicSource); }

The above code is a basic implementation of adding RF energy harvesting capability to sensor nodes in NS3. It creates an EnergyHarvester object specifically for RF energy harvesting and attaches it to each sensor node in the simulation scenario.

Hi hassan,

To simulate RF energy harvesting in MATLAB, you can use the RF toolbox. The RF Toolbox provides functions for analyzing, designing, and simulating RF systems .

Here's a general approach:

• Create a Simulink Model: Set up a Simulink model with a sensor node, a power source, and an energy storage component.
• Model RF Energy Harvesting: Use Simulink blocks (e.g., Gain, Sum, Integrator) to represent the RF energy harvesting process. Model the power received from the RF source and the energy stored in the battery.
• Implement Leach Protocol: Incorporate the Leach protocol logic into your model, including cluster formation, data transmission, and energy consumption.
• Simulate: Run the simulation to observe the effects of RF energy harvesting on the sensor network's performance.

Key Considerations:

• RF Energy Source: Model the RF energy source (e.g., base station) and its characteristics.
• Propagation Model: Use a suitable propagation model to calculate the received power at the sensor node.
• Antenna Characteristics: Consider the antenna gain and efficiency of both the transmitting and receiving devices.
• Energy Storage: Model the battery or other energy storage component.
• Leach Protocol Implementation: Ensure accurate implementation of the Leach protocol's clustering, data aggregation, and energy consumption mechanisms.
