2026 Quantum-Inspired Meta-PPO for Trust-Aware Semantic Offloading in Digital Twin-Enabled IoV Networks With Energy Harvesting
abstract
The convergence of intelligent transportation, digital twin (DT) ecosystems, and vehicular edge intelligence is reshaping smart cities. With the rise of autonomous and context-aware vehicles, ultra-reliable, low-latency, and energy-efficient task orchestration frameworks are crucial in Internet of Vehicles (IoV) networks. In mission-critical situations, such as emergency response routing, disaster relief, and high-priority health transport, semantic task offloading must account for trust, adapt to high vehicle mobility, edge node reliability, and energy limitations. This paper proposes a quantum-inspired meta Proximal Policy Optimization (Qi-mPPO) algorithm for trust-aware semantic offloading in DT-enabled IoV systems with wireless energy harvesting. The approach leverages variational quantum circuits integrated with meta-learning to address non-stationary environments. A multi-objective reward function is formulated to jointly optimize latency, energy efficiency, semantic accuracy, and trust preservation. To ensure semantic relevance under vehicular mobility and energy constraints, quantum-informed policy regularization is applied. Simulation results demonstrate that Qi-mPPO outperforms classical and meta-reinforcement learning baselines in convergence rate, task latency, trust robustness, and energy consumption under realistic vehicular conditions.

2024 Ontology-Based Reinforcement Learning for Semantic Offloading in MEC-Enabled 6G IoT Networks
abstract
The proliferation of ultra-low-latency and faster convergence applications in sixth-generation (6G) networks necessitates mobile edge computing (MEC) for offloading computationally intensive tasks from user devices to the network edge. However, traditional offloading approaches ignore the semantic aspects of tasks and resources. This paper proposes a novel ontology-based reinforcement learning (ORL) approach for optimal semantic offloading decisions in evolving dynamic MEC-enabled 6G networks, considering network uncertainty and time variation conditions. The proposed ORL approach integrates a dynamic learning mechanism that adjusts and captures semantics task resources, enabling adaptive real-time offloading decisions to satisfy task processing requirements and user demands. The numerical results demonstrate significant improvements in latency reduction, responsiveness, and adaptability compared to traditional offloading approaches.

2024 Adaptation in Edge Computing: A Review on Design Principles and Research Challenges
abstract
Edge computing places the computational services and resources closer to the user proximity, to reduce latency, and ensure the quality of service and experience. Low latency, context awareness and mobility support are the major contributors to edge-enabled smart systems. Such systems require handling new situations and change on the fly and ensuring the quality of service while only having access to constrained computation and communication resources and operating in mobile, dynamic and ever-changing environments. Hence, adaptation and self-organisation are crucial for such systems to maintain their performance, and operability while accommodating new changes in their environment. This article reviews the current literature in the field of adaptive edge computing systems. We use a widely accepted taxonomy, which describes the important aspects of adaptive behaviour implementation in computing systems. This taxonomy discusses aspects such as adaptation reasons, the various levels an adaptation strategy can be implemented, the time of reaction to a change, categories of adaptation technique and control of the adaptive behaviour. In this article, we discuss how these aspects are addressed in the literature and identify the open research challenges and future direction in adaptive edge computing systems. The results of our analysis show that most of the identified approaches target adaptation at the application level, and only a few focus on middleware, communication infrastructure and context. Adaptations that are required to address the changes in the context, changes caused by users or in the system itself are also less explored. Furthermore, most of the literature has opted for reactive adaptation, although proactive adaptation is essential to maintain the edge computing systems’ performance and interoperability by anticipating the required adaptations on the fly. Additionally, most approaches apply a centralised adaptation control, which does not perfectly fit the mostly decentralised/distributed edge computing settings.

2024 Quantum Deep Reinforcement Learning for Dynamic Resource Allocation in Mobile Edge Computing-Based IoT Systems
abstract
This paper exploits a quantum-empowered machine learning algorithm to enhance computation learning speed. We leverage quantum phenomena such as superposition and entanglement to work on large-scale multi-dimensional data represented by quantum states. Under stochastic behaviors and quantum uncertainty, we examine the offloading problem to maximize the computational task processing efficiency, considering the computation latency, energy consumption, and quantum network adaptability. From the Markov decision process, the paper proposes a novel quantum-empowered deep reinforcement learning (Qe-DRL) approach, combining quantum computing theory and machine learning to achieve exploration and exploitation trade-off via quantum parallelism significantly. Furthermore, we develop a modified Grover’s algorithm with exponential convergence speed to provide a searching strategy for transition quantum states probabilities. Simulation results establish the effectiveness of the proposed Qe-DRL algorithm and its superior computational learning speed. Our proposed Qe-DRL algorithm outperforms other benchmarks in terms of energy efficiency performance.

2023 Stochastic geometry modelling and analysis for cooperative NOMA with large transmit antennas for 5G applications and beyond
abstract
Abstract Among the technologies that have made 5G wireless communication successful are non‐orthogonal multiple access (NOMA) and cooperative NOMA. The distinction is that cooperative NOMA adds coding schemes to improve performance. Nevertheless, research on cooperative NOMA has primarily used theoretical correlation‐based stochastic models (CBSM) instead of geometric‐based stochastic models (GBSM) that represent suitable channel conditions by including characteristics like path loss, delay profile, and angle of arrival in the model. This paper connects the low adoption of GBSM is due to computational challenges. Given this, it is essential to assess cooperative NOMA that employs GBSM with large antenna transmitters to meet future 5G expectations. The cooperative NOMA system's transmitter is modelled as a uniform rectangular array and a novel channel realisation is proposed for analysis. The location vector of the antenna using the physical dimension of the array is defined to reduce computational problems. Results shows that the average bit‐error performance of GBSM matches that of CBSM at the same antenna element separation, but the spatial correlation between antenna elements significantly impacts the outage probability and average achievable rates of GBSM performance. Enhanced GBSM performance by increasing antenna separation at the transmitter above one‐eighth wavelength.

2023 Novel Online Network Intrusion Detection System for Industrial IoT Based on OI-SVDD and AS-ELM
abstract
The Industrial Internet of Things (IIoT) should be equipped with computational resources to detect network intrusions, types of attacks, and update their models automatically in real time. The most challenging aspect of machine learning (ML)-based network intrusion detection system (NIDS) design to secure IIoT is the continuous need for up-to-date definitions of attack data records. Moreover, the approaches employed by cyber attackers are in a dynamic state with changing trends and techniques. Hence, conventional signature-based NIDS are not suitable since they cannot update obsolete detection models. Anomaly-based NIDS that contains an online learning technique is adopted in our proposed method. Since IIoTs face resource-constrained problems, such as low memory, low computing capacity, and limited energy supply, it is very challenging to implement the exiting general-purpose anomaly-based NIDS. This article proposes a lightweight NIDS based on an online incremental support vector data description (OI-SVDD) anomaly detection system on the IIoT devices and an adaptive sequential extreme learning machine (AS-ELM) on the multiaccess edge computing (MEC) server. Additionally, we utilize the MEC server, which provides computational resources to execute the AS-ELM model at the network’s edge. To avoid data saturation in the proposed model, we apply data filtering using the rate of convergence (ROC). We evaluated the proposed NIDS through experiments using two data sets, such as UNSW-NB15 (public data set) and our self-generated data set. Our results show that the proposed OI-SVDD and AS-ELM perform effectively and detect network intrusion in a realistic IIoT environment.

2023 An Adaptive Network Security System for IoT-Enabled Maritime Transportation
abstract
With the rapid growth of the Internet of Things (IoT) applications in Maritime Transportation Systems (MTS), cyber-attacks and challenges in data safety have also increased extensively. Meanwhile, the IoT devices are resource-constrained and cannot implement the existing security systems, making them susceptible to various types of debilitating cyber-attacks. The dynamics in the attack processes in IoT-enabled MTS networks keep changing, which makes a traditional offline or batch ML-based attack detection systems intractable to apply. This paper provides a novel approach of using an adaptive incremental passive-aggressive machine learning (AI-PAML) method to create a network attack detection system (NADS) to protect the IoT devices in an MTS environment. In this paper, we propose an NADS that utilizes a multi-access edge computing (MEC) platform to provide computational resources to execute the proposed model at a network end. Since online learning models face data saturation problems, we present an improved approximate linear dependence and a modified hybrid forgetting mechanism to filter the inefficient data and keep the detection model up-to-date. The proposed data filtering ensures that the model does not experience a rapid increase in unwarranted data, which affects the model's attack detection rate. A Markov transition probability is applied to control the MEC selection and data offloading process by the IoT devices. The performance of the NADS is verified using selected benchmark datasets and a realistic IoT environment. Experimental results demonstrate that AI-PAML achieves remarkable performance in the NADS design for an MTS environment.
