Detailed Description

BasicEnergyHarvester increases remaining energy stored in an associated Energy Source.

Introspection did not find any typical Config paths.

The BasicEnergyHarvester implements a simple model in which the amount of power provided by the harvester varies over time according to a customizable generic random variable and time update intervals.

Unit of power is chosen as Watt since energy models typically calculate energy as (time in seconds * power in Watt).


Attributes

  • PeriodicHarvestedPowerUpdateInterval: Time between two consecutive periodic updates of the harvested power. By default, the value is updated every 1 s
    • Set with class: ns3::TimeValue
    • Underlying type: Time –9223372036854775808.0ns:+9223372036854775807.0ns
    • Initial value: +1000000000.0ns
    • Flags: construct write read
  • HarvestablePower: The harvestable power [Watts] that the energy harvester is allowed to harvest. By default, the model will allow to harvest an amount of power defined by a uniformly distributed random variable in 0 and 2.0 Watts
