Enhancing the physical layer security in IoT over mixed Rayleigh-Nakagami-m fading channels with untrustworthy relaysdoi:10.1007/s12243-025-01064-6The Internet of Things (IoT) enables 5G communication, and it is widely used in many industries owing to its ability to connect a massive number of...
Physical-Layer Security in the Internet of Things: Sensing and Communication Confidentiality Under Resource Constraints The Internet of Things (IoT) will feature pervasive sensing and control capabilities via a massive deployment of machine-type communication (MTC) devices. ... A Mukherjee - 《...
thedata link layer, onto the pins and across the wires of atwisted-paircable. From an optical standpoint, the physical layer converts a stream ofzeros and onesonto fiber using light as its physical medium. Lastly, the physical layer uses a wireless transmitter to convert these bits...
Physical layer security in massive internet of things: delay and security analysis Delay and security are both highly concerned in massive internet of things (IoT) which is a promising application scenario in 5G wireless communication sys... S Zhang,X Xu,J Peng,... - 《Communications Iet》 被...
2.5Physical layer (Perception layer) Thephysical layeris the initial layer of the IoT reference model that deals with the things/devices of IoT. The “things” in IoT refers to different end devices that transmit and receive data. The layer includes sensors, actuators, and controllers. The powe...
Physical Layer Processing refers to the set of procedures and protocols involved in the processing of information at the physical layer of the IEEE 802.16m standard. It includes various steps and control signaling to improve performance, increase throughput and capacity, reduce latency, support user ...
DMRS is used to estimate the radio channel for demodulation. DMRS is UE-specific, can be beamformed, confined in a scheduled resource, and transmitted only when necessary, both in DL and UL. To support multiple-layer MIMO transmission, multiple orthogonal DMRS ports can be schedu...
In order to support URLLC, there should be both evolutionary and revolutionary changes in the air interface named 5G NR. In this article, we provide an up-to-date overview of URLLC with an emphasis on the physical layer challenges and solutions in 5G NR downlink. We highlight key ...
The Physical Layer is the lowest layer in the OSI model, and is the only layer where a subsystem in one open system communicates directly with the corresponding subsystem in another. Its function is to transfer information transparently between physical service users (data link entities). This tra...
In subject area: Computer Science Physical layer security refers to a technique used to enhance the security of IoT systems by exploiting the physical properties of the network system. It differs from cryptographic approaches and ensures secrecy by utilizing factors such as interference, channel securit...
