“…The basic power consumption is much lower in 802.11ac, but the 802.11ad interface always consumes a lot of energy when it is active. There is no big difference when receiving or transmitting data compared to the basic power consumption according to [32]. However, the results indicate that with the latest models, the best option for energy saving is to send the data with the best possible data rate in order to be able spend more time in the basic power consumption mode.…”

“…The more recent 802.11n model that was defined in [30] based on measurements reported in [20] is quite flat.

The most recent 802.11ac and 802.11ad measurements given in [32] show that both receiver power consumption and transmitter power consumption are almost flat, regardless of the bit rate.…”

Device-to-device (D2D) communication is an essential part of the future fifth generation (5G) system that can be seen as a "network of networks," consisting of multiple seamlessly-integrated radio access technologies (RATs). Public safety communications, autonomous driving, socially-aware networking, and infotainment services are example use cases of D2D technology. High data rate communications and use of several active air interfaces in the described network create energy consumption challenges for both base stations and the end user devices. In this paper, we review the status of 3rd Generation Partnership Project (3GPP) standardization, which is the most important standardization body for 5G systems. We define a set of application scenarios for D2D communications in 5G networks. We use the recent models of 3GPP long term evolution (LTE) and WiFi interfaces in analyzing the power consumption from both the infrastructure and user device perspectives. The results indicate that with the latest radio interfaces, the best option for energy saving is the minimization of active interfaces and sending the data with the best possible data rate. Multiple recommendations on how to exploit the results in future networks are given.

“…In the simulations, the APs and relays are uniformly deployed in the region, and the clients are randomly distributed. According to the power consumption of commodity 60 GHz devices, 32 we set that the base power consumption of AP

P_{i}^{b}

is 1.938W, the base power consumption of relay

P_{k}^{b}

is 1.292W, the per‐client communication power consumption of AP

P_{i}^{c}

is 0.2202W, and the per‐client communication power consumption of relay

P_{k}^{c}

is 0.1468W. In addition, the transmission radius of each AP and relay node θ i is 10m.…”

Dual-hop 60 GHz wireless networks which support relay-assisted dual-hop transmission have been widely adopted in the recent years, aiming to prolong communication distance and bypass obstacles in 60 GHz band. However, it is very challenging to perform link scheduling in such dual-hop architecture while considering several factors, i.e., reducing network power consumption, avoiding overloaded APs/relays and adapting to network dynamics. To this end, we investigate the problem of energy-efficient link scheduling with load constraints (ELL), and propose solutions to deal with network dynamics. First, we present a fine-grained energy model for dual-hop 60 GHz networks, and formulate the ELL problem as an integer linear programming model that aims to minimize the network power consumption, while satisfying AP/relay load constraints. Then, we propose a polynomial-time global scheduling algorithm that obtains a near-optimal link scheduling solution via iterative relaxation, and the load constraint at each AP/relay can only be violated by at most an additive constant of two. Moreover, we present a local adjustment algorithm to adjust link-scheduling solutions efficiently, such as client arrival/departure and link blockage, and design a hybrid algorithm that combines global scheduling and local adjustment. Finally, we conduct simulation experiments that validate our algorithms' effectiveness and efficiency.
