Energy‐Aware Optimisation for Off‐Grid ORAN With RIS and Edge Computing

IET Networks, Volume 14, Issue 1, January/December 2025.
Energy‐conscious off‐grid ORAN builds on solar‐powered remote units, separate DU/CU functionality, RIS components and a means for core network connection. ABSTRACT This paper proposes a strategy for designing Open Radio Access Networks (ORAN) to maximise their energy efficiency using solar power, supplemented by Reconfigurable Intelligent Surfaces (RIS)

Secrecy Performance of Finite-Sized Cooperative Single Carrier Systems With Unreliable Backhaul Connections

IEEE Transactions on Signal Processing, 2016
In this paper, the secrecy performance of finite-sized cooperative cyclic prefixed single carrier systems with multiple eavesdroppers and unreliable wireless backhaul connections across multiple transmitters is investigated. For nonidentical frequency-selective fading channels between the relay and destination nodes, secrecy performance metrics ...

LoRaSync: Energy efficient synchronization for scalable LoRaWAN

Transactions on Emerging Telecommunications Technologies, Volume 35, Issue 2, February 2024.
LoRaSync is an energy‐efficient synchronization mechanism designed to support the implementation of slotted medium access control protocols for LoRa networks. Its robust design is based on real clock drift measurements, and a synchronization beacon skipping strategy is used in order to save power on the end‐devices Abstract Low‐power wide‐area networks

Minimum Expected Distortion in Gaussian Source Coding with Fading Side Information

, 2012
An encoder, subject to a rate constraint, wishes to describe a Gaussian source under squared error distortion. The decoder, besides receiving the encoder's description, also observes side information consisting of uncompressed source symbol subject to ...

Secure Cooperative Single Carrier Systems Under Unreliable Backhaul and Dense Networks Impact

IEEE Access, 2017
In this paper, the impacts of unreliable backhaul links on the secrecy performance of cooperative single carrier heterogeneous networks in the presence of eavesdroppers are investigated. A two-phase transmitter/relay selection scheme is proposed, where the best transmitter is selected to maximize signal-to-noise ratio at the relays in the first phase ...

Network Neutrality: A Research Guide [PDF]

, 2013
The conclusion in a research handbook should emphasise the complexity of the problem than trying to claim a one-size-fits-all solution. I have categorised net neutrality into positive and negative (content discrimination) net neutrality indicating the ...
