“…VST‐TDMA [1] is a MAC protocol that efficiently schedules the surrounding nodes. It does this in a manner that the idle time of the base station is negligible insofar as there are any pending transmissions queued (in any direction).…”

“…If the node is equipped with an EDH, the protocol can slow down the transmission to reach an energy balance. The following expression specifies the minimum sleep time that must be introduced to achieve energy self‐sustainability [1].

t_{s s s} = \frac{\sum_{n \in state} (P_{n}^{⊙} - P^{\otimes}) t_{n}^{⊙}}{P^{\otimes} - P_{normalsleep}^{⊙}}

The energy harvesting rate is given by

P^{\otimes}

and the power of the discharge states is denoted by

P_{normalstate}^{⊙}

, except for the power consumed by the sleep state, which is denoted by

P_{normalsleep}^{⊙}

.…”

“…These objectives are the drivers of this work. The VST‐TDMA [1] is a MAC protocol designed with the flexibility and versatility to handle this systematic process. This protocol, with the incorporation of battery status information and an accurate battery‐energy model, can estimate the battery depletion time and, as a corollary, avoid consuming the entire charge.…”

Energy independence is a wireless device quality that demands the utmost exigency. Energy harvesting devices (EHD) alleviate the energy constraints demanded by these nodes and with the use of protocols, such as variable slot time-time division multiple access (VST-TDMA) energy self-sustainability can be attained at the cost of throughput. To allow high throughput levels and self-sustainability the system can allow the power consumption to be greater than the energy harvesting rate while a state-of-charge (SoC) of 30% or greater is maintained. To achieve this the system must accurately estimate the SoC, which is not a trivial task. In this work, a battery model is incorporated into the VST-TDMA protocol to estimate the battery model parameters, including the SoC, which successfully allows it to maintain appropriate SoC levels.
