This paper proposes computationally efficient algorithms to maximize the energy efficiency in multi-carrier wireless interference networks, by a suitable allocation of the system radio resources, namely the transmit powers and subcarrier assignment. The problem is formulated as the maximization of the system global energy efficiency (GEE) subject to both maximum power and minimum rate constrain...

The development of advanced and intelligent measurement instruments in recent years has increased the intelligence modern energy systems, especially power systems. Besides, with advancement conversion technologies, these systems benefit from multi-carrier resources. Accordingly, this paper presents a model smart city which considers various components, including transportation system (STS), mic...

We present our “Zero Energy Network” (ZEN) protocol stack for energy harvesting wireless sensor networks applications. The novelty in our work is 4 fold: (1) Energy harvesting aware fully featured MAC layer. Carrier sensing, Backoff algorithms, ARQ, RTS/CTS mechanisms, Adaptive Duty Cycling are either auto configurable or available as tunable parameters to match the available energy (b) Energy ...

In this paper, component carrier selection and beamforming on carrier aggregated channels in Heterogeneous Networks are proposed. The scheme jointly selects the component carrier and precoding (i.e. beamforming) vectors with the cooperation of the other cells to deal with the interference between Macro cell and Pico cell. The component carrier selection and beamforming is achieved by optimizing...

in recent years, the issue of energy consumption modeling techniques in the building sector has been widely considered by researchers and managers. researches indicate that energy consumption in residential sector is one of the main parts of the total consumption. moreover, the urban residence is supposed as a significant consumer of energy in every country and therefore a focus for energy cons...

Fog computing (FC) models the cloud paradigm expedient by bridging breach between centralized data servers and diverse terrestrially distributed applications. It wields various wireless sensor networks (WSNs) that sprawl in core of any IoT Consequently, operation fog network turns on efficiency WSNs operation, while all-inclusive energy consumption depends both FC operation. This paper addresse...

Abstract— In this paper, we extend both Bianchi’s and Kumar’s models and characterize the channel activities governed by IEEE 802.11 DCF in multi-hop wireless networks from the perspective of an individual sender. In particular, we incorporate the effect of PHY/MAC attributes (such as transmit power and physical carrier sense) that need not be considered in WLANs but become extraordinarily impo...

The increasing energy consumption driven by striking growths in the number of users and data usage has placed cost reduction and energy efficiency at the forefront of system design. As a step towards incorporating more energy friendly mobile platforms in future networks, 3GPP LTE-Advanced has adopted Coordinated Multi-Point (CoMP) transmission/reception due to its ability to mitigate and/or coo...
