“…Hence, actual values for the parameters the power consumed in idle listening, transmission, receiving, and sleeping depend on the implementation. Despite that, our analysis in based on the characteristics of MAC layer and fixed‐power model is valid in general. In summary, the new 802.11n uses MIMO orthogonal frequency‐division multiplexing (OFDM) technology to achieve high‐throughput communications, but it also suffers higher power consumption in MIMO mode with the use of a more sophisticated modulation coding scheme such as modulation coding scheme (MCS) 31.…”

“…With the previous model and previous works , we can have the energy consumed in DIFS, back‐off, transmission, SIFS, ACK, and possible retransmission for collision occurrences to upload a data frame. If we sum up the energy consumptions listed in Equations (8), (10), (14), (16), (18), and (19) in , we obtain the total energy consumptions for the transmission of one frame, Total e , by

\begin{matrix} leftalign \\ rightalign-odd {T otal}_{e} & align-even = {D IFS}_{e}^{M} + {Backoff}_{e}^{M} + {T ran}_{e}^{M} + {R ecv}_{e}^{M} & rightalign-label & align-label \\ rightalign-odd & align-even + S IFS \times {i dle}_{p} + {C oll}_{e}^{M} & rightalign-label (6) \end{matrix}

To be compatible with the legacy 802.11, there are two major medium access control (MAC) behaviors, high throughput (HT) and non‐high throughput (non‐HT), in the 802.11n. In this paper, we analyze and compare the energy efficiencies of different MAC behaviors in 802.11n on the basis of the Bianchi model and our previous works to evaluate the performance of the different MAC behaviors regarding HT and non‐HT. Our studies try to provide the decision for the mobile stations to enable the HT of 802.11n or not based on the consideration of energy efficiency. Studies show that owing to the large power consumption in HT, it is not suitable for limited power devices to carry WWW traffics by multiple‐input multiple‐output transmission because of large overheads of physical layer in the HT mode. However, if large file transmissions by File Transfer Protocol are considered, the energy efficiency in HT MAC can be very high because of the large aggregated frame size. It is especially true when the number of active stations is large because of the decrease in idle listening time by using the techniques applied in HT MAC such as Aggregate MAC Protocol Data Unit and Block‐ACK. These characteristics in the HT mode can overwhelm the larger overheads of physical layer compared with that in the non‐HT mode when large files are needed to be uploaded.

“…However, if the medium is busy, the node attempts a backoff procedure. During the backoff procedure, the node selects a random number of slots to wait between (0, CW), where CW is the Contention Window [13]. The node then decrements the random backoff period as long as the channel is idle.…”

“…In the beacon enabled mode, nodes employ slotted CSMA/CA to access the channel. In the non-beacon mode, nodes employ unslotted CSMA/CA where the packet transmission and backoff periods are not aligned with a slot boundary like in the slotted version [13]. In the unslotted CSMA/CA mode, the node performs Clear Channel Assessment (CCA) once for a duration CCA T to ensure that the medium is free before transmitting data.…”

This paper proposes a methodology for calculating the energy consumed by a Wireless Sensor Network as well as its throughput under the effect of a jamming node modelling interference to account for collisions and retransmissions. Accordingly, the proposed methodology takes into consideration retransmissions and data dropped due to interference and collisions simultaneously. Simulations are conducted using OPNET to model various scenarios utilizing off-the-shelf wireless communication standards, namely ZigBee, Wi-Fi and Low Power Wi-Fi. A figure of merit is developed to offer more representative results for applications with different requirements. In achieving different requirements for a given application, there is a clear trade-off between energy consumption and throughput.
