Energy-Efficient Adaptive Modulation and Data Schedule for Delay-Sensitive Wireless Communications

Energy-efficient design in wireless communications networks

Toward Energy-Efficient 5G Wireless Communications Technologies

The densification and expansion of wireless networks pose new challenges on energy efficiency. With a drastic increase of infrastructure nodes (e.g. ultra-dense deployment of small cells), the total energy consumption may easily exceed an acceptable level. While most studies focus on the energy radiated by the antennas, the bigger part of the total energy budget is actually consumed by the hard...

An Energy-Efficient MAC Protocol for Delay-Sensitive Wireless Sensor Networks

Abstract. In this paper, we propose a new medium access control protocol for wireless sensor networks, named LE-MAC (Latency and Energy aware MAC) that aims to minimize data delivery latency as well as energy consumption. To achieve both goals, we exploit a physical carrier sensing feature in CSMA/CA and combine it with a cross-layer technique. When nodes that are in routing path between source...

Statistical physics inspired energy-efficient coded-modulation for optical communications.

Because Shannon's entropy can be obtained by Stirling's approximation of thermodynamics entropy, the statistical physics energy minimization methods are directly applicable to the signal constellation design. We demonstrate that statistical physics inspired energy-efficient (EE) signal constellation designs, in combination with large-girth low-density parity-check (LDPC) codes, significantly ou...
