MAC Protocol Design for Optical Wireless Body‐Area Networks: Latency, Energy Efficiency and Scalability Analysis

IET Networks, Volume 15, Issue 1, January/December 2026.
This work investigates suitable MAC protocols for medical optical wireless body‐area networks (WBANs), focussing on multiple access management. Using realistic channel models, we evaluate the network performance in terms of energy efficiency, quality‐of‐service and scalability for different IEEE protocols, for both intra‐ and extra‐WBAN connectivity in

Deep Reinforcement Learning Reconfigurable Smart Surface Sensing MAC Protocol for Terahertz Mesh Networks

IET Networks, Volume 15, Issue 1, January/December 2026.
This paper proposes a reconfigurable intelligent surface‐based deep reinforcement learning MAC (RIS‐DRL‐MAC) protocol for terahertz mesh networks. By embedding RIS perception into the MAC decision loop and using a distributed TD3 algorithm, the proposed scheme achieves a cross‐layer optimisation of beam direction, access timing and RIS phase control ...
