Energy-Efficient Reconfigurable Holographic Surfaces Operating in the Presence of Realistic Hardware Impairments
Qingchao Li, Mohammed El-Hajjar, Yanshi Sun +3
Reconfigurable holographic surfaces (RHSs) constitute a promising technique of supporting energy-efficient communications. In this paper, we formulate the energy efficiency maximiz…
Achievable Rate Analysis of Intelligent Omni-Surface Assisted NOMA Holographic MIMO Systems
Qingchao Li, Mohammed El-Hajjar, Yanshi Sun +4
An intelligent omni-surface (IOS) assisted holographic multiple-input and multiple-output architecture is conceived for full-space coverage at a low energy consumption.…
Seamless Handover in IP over ICN Networks: a Coding Approach
Mohammed Al-Khalidi, Nikolaos Thomos, Martin J. Reed +2
Seamless connectivity plays a key role in realising QoS-based delivery in mobile networks. However, current handover mechanisms hinder the ability to meet this target, due to the h…
Anchor Free IP Mobility
Mohammed Al-Khalidi, Nikolaos Thomos, Martin J. Reed +2
Efficient mobility management techniques are critical in providing seamless connectivity and session continuity between a mobile node and the network during its movement. Current m…
Ultra-Reliable Cloud Mobile Computing with Service Composition and Superposition Coding
Seyyed Mohammadreza Azimi, Osvaldo Simeone, Onur Sahin +1
An emerging requirement for 5G systems is the ability to provide wireless ultra-reliable communication (URC) services with close-to-full availability for cloud-based applications.…
Stateless multicast switching in software defined networks
Martin J. Reed, Mays Al-Naday, Nikolaos Thomos +3
Multicast data delivery can significantly reduce traffic in operators' networks, but has been limited in deployment due to concerns such as the scalability of state management. Thi…
