DETERMINING AND COMMUNICATING RECHARGING TIME OF AN ENERGY HARVESTING DEVICE

An energy harvesting electronic device that includes an energy storage device and a processor is provided. The processor is configured to determine that the electronic device has a first message to transmit to another electronic device. The processor determines that the device has enough energy required for transmitting the first message and a first amount of time required for the energy storage device to store an amount of energy required for receiving a second message after transmitting the message. The processor includes a value in the first message that is at least equal to the first amount of time when the first amount of time is greater than zero. The processor includes an indication in the first message that the electronic device has enough energy required for receiving the second message when the first amount of time is zero. The processor transmits the first message to the other electronic device.
