By integrating embedded sensors, actuators, and communication modules, IoT systems can gather real-time data, leading to better operational decisions and improved efficiency in healthcare systems. The rapid growth of IoT devices creates three main operational challenges related to power usage, efficiency, and thermal management requirements. The demand for more efficient, compact, high-speed, and energy-efficient devices poses significant challenges for these systems. Traditional complementary metal-oxide-semiconductor (CMOS)-based architectures struggle to meet these demanding requirements, representing a major barrier to the development of reliable and scalable next-generation IoT systems. This research demonstrates Quantum-Dot Cellular Automata (QCA) nanotechnology as an alternative solution because it performs logical operations through electron positioning rather than conventional current flow. This paper proposes a modified version of a QCA-based multiplexer design (MUX) since digital logic systems require these signal routing elements for operation. The fundamental 2:1 MUX is established using QCA cell-interaction principles, and then 4:1 and 8:1 QCA MUXs are designed through hierarchical expansion. The suggested modified MUX devices operate on a compact scale with minimal cells to reduce the occupied area compared to current MUX designs. The research outcomes demonstrate that QCA circuits hold promising potential for creating energy-saving, powerful, and scalable computational platforms for future IoT healthcare systems.</div></div>","PeriodicalId":54336,"journal":{"name":"Nano Communication Networks","volume":"46 ","pages":"Article 100595"},"PeriodicalIF":4.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145333475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents TRMAC, a novel cross-layer MAC protocol that exploits the spatial focusing capability of Time Reversal (TR) to enable multiple parallel transmissions over a shared frequency channel. By leveraging the quasi-deterministic nature of on-chip wireless channels, TRMAC pre-characterizes Channel Impulse Responses (CIRs) to coordinate access using energy-based thresholds, eliminating the need for orthogonal resource allocation or centralized arbitration. Through detailed physical-layer simulation and system-level evaluation on diverse traffic, TRMAC demonstrates comparable or superior performance to existing multi-channel MAC protocols, achieving low latency, high throughput, and strong scalability across hundreds of cores. Moreover, we prove that TRMAC can be utilized for parallel transmissions with a single frequency channel with a similar throughput and latency as in using multiple frequency bands, omitting the need for complex transceivers.</div></div>","PeriodicalId":54336,"journal":{"name":"Nano Communication Networks","volume":"46 ","pages":"Article 100593"},"PeriodicalIF":4.7,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145227620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As classical systems approach their miniaturization and energy-efficiency limits, quantum technologies offer new mechanisms rooted in superposition, entanglement, and reversibility. This paper introduces a foundational nanocommunication framework that integrates three known reversible circuit primitives—majority voter, parity generator, and parity checker—into a unified communication system. Unlike prior works that analyze these circuits in isolation, the proposed architecture validates their combined functionality on the IBM Quantum platform, tested under both ideal (Aer simulator) and realistic noisy (NISQ hardware) conditions. By incorporating depolarizing noise models, mid-circuit resets, and hardware execution, the framework directly reflects the physical constraints of real devices, including qubit errors, decoherence, and relaxation effects. Simulation and hardware results demonstrate system-level fidelity, circuit cost, and accuracy for both small- and higher-bit counts. Comparative analysis with existing teleportation- and entanglement-based protocols highlights the efficiency and scalability of the approach.

With the advancement of nano-devices and terahertz communication technology, the performance of intra-body nanonetworks has been continuously enhanced, making the remote medical data transmission a reality.

Considering the aqueous environment of the human body, the communication of nanonetworks is subject to environmental interference and the physical limitations of nano-devices, and traditional routing protocols are difficult to meet the communication requirements in intra-body nanonetworks. Especially in the aspect of health monitoring,different types of data have corresponding importance, and some urgent data deserve more attention. For example, signals of acute arrhythmias (such as ventricular fibrillation) detected by nano-nodes are of the highest priority. Therefore, this paper designs a Data Priority-based Opportunistic Routing (DPOR) protocol. In this protocol, nano-nodes select the appropriate relay according to the level of data priority to improve the transmission efficiency of intra-body nanonetworks.

By restricting the energy of nano-nodes and managing the energy consumption of nodes, it prevents nodes from overheating and damaging human tissues.

Two different tunable absorbers have been proposed. In absorber I, tunability is introduced by varying the chemical potential of graphene strips which act as switches while in absorber II, tunability is facilitated by using multiple graphene patches embedded in slotted silver patches. Equivalent circuit models (ECM) have been proposed for modelling the electromagnetic coupling between different constituents in the absorbers by lumped parameters for analysing the reflection characteristics. This study is vital for comprehending the effect of the absorber geometry in determining the resonant frequencies corresponding to peak absorption and reflection nulls. The surface current distribution aids in determining whether electric or magnetic resonances are formed in the absorber. The tunable absorbers achieved a maximum sensitivity of 435 GHz/RIU. Maximum quality factor of 319 and figure of merit (FOM) of 11 have been obtained. The proposed absorbers can be used in detecting cancerous cells of human skin when the latter is placed as an analyte over it. Distinct 2D images of healthy and cancerous cells have been reconstructed from the reflection characteristics of the absorber when placed in vicinity of human skin which ensures that it can be used as a biosensor for non-invasive detection of skin cancer at an early stage.

At lower threshold levels, the issues with current leakage and dissipated energy in CMOS have become apparent. As a result, researchers are exploring alternatives that could replace CMOS in the coming years. Quantum dot cellular automata (QCA), a recently created transistor-free structure with tremendous chip density, exceptionally low power consumption, and speedy processing operations, is one of the crucial technologies that can be utilized as a substitute for CMOS technology. The configurable logic module (CLM) is one of the most important digital structures that are useful in FPGA circuits. The previous configurable logic module suffers from a high occupied area and low speed, so it is necessary to solve all the previous shortcomings by implementing it in a suitable technology such as QCA to increase the efficiency of the entire field-programmable gate array (FPGA) circuit. If the programmable circuit is quick, power-conscious, and nano-sized, the effectiveness of high-end complex circuits like the FPGA is considerably increased. In the QCA, configurable systems are not addressed much. The present paper examines the exploration of the conception and implementation of an innovative CLM within the QCA framework, incorporating nano communication networks. A D flip flop, a programmable block (PB), and a multiplexer are used in the construction of the module under examination, which is enhanced with nano communication networks for improved functionality. This module’s durability can be ascribed to the skillful development of both sequential and combinational circuits, combined with the benefits of nano communication networks. The implementation of sophisticated circuits, such as 2-bit, 3-bit, and 4-bit slice designs for FPGA, demonstrates the suggested module’s flexibility and versatility. When compared to an identical circuit that already exists, the QCA-based 4-bit slice circuit that has been recommended has exhibited a considerable improvement in cell count and area. Compared to the best previous coplanar architecture, the suggested 4-bit slice performed 30 % and 40 % better regarding the area and cell count, respectively. In addition, when compared to the best 16-bit LUT design, the suggested structure has produced results that are 14.72 percent and 3.81 percent more effective regarding area and cell count, correspondingly.
