“…However, if the size of the data frame is larger than the maximal frame size in non-HT, 2304 (nonencrypted) or 2312 (encrypted) octets, the number of times to upload to the Internet relayed by AP is greater than 1 if non-HT MAC is adopted. The threshold size of data sent by a station to enable HT can be illustrated by Figures 7-9 and Tables VI-VIII on the basis of the model proposed in the previous sections and Equations (8) and (9). Here, NonHT_1 and HT_1 denote the energy consumptions operated in non-HT and HT MAC, respectively, when the number of active stations is 1.…”

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.

“…To raise the energy efficiency of 802.11, Ting et al [79] proposed an intelligent idle-listening and ultra-light sleeping mode to reduce the energy consumption during the DIFS and backoff idle time. The propose lets the mobile devices wake up for a short period of time, e.g.…”

“…In fact, this transition requires energy and it also takes time, so it needs criteria for these UEs to decide whether go to sleep or not after the expiration of inactive timer (I-Timer) in the DRX cycle. In this chapter, the concept of light sleeping mode [79] is also applied to shorten this wakeup time and reduce transition energy.…”

Intention of this work is to investigate the opportunity and feasibility of more energy efficient networking in wired Home and Building Automation Systems, which have traditionally devoted a relatively little attention to this issue, especially if compared to wireless networks. This paper will propose a solution to address the problem by evaluating the introduction of power state switching in a real scenario and defining the concept of functional and spatial adjacency among packets. The impact of adopting such approach will be assessed through a simulation aimed at determining the best trade-off between energy and Quality of Service 1 .
