Tour Path Scheduling Using Optimized Deep Reinforcement Learning for IoT Mobile Data Collectors P. Kalyana Sundari, R. Vadivel International Journal of Communication Systems, 2026 In Internet of Things (IoT)–based wireless sensor network (WSN), mobile data collectors (MDCs), which move over various geographic regions to transport data from sensors to access points, are thought to be a more effective way than the traditional data collection techniques employing static sinks. The direct transfer of data from all sensors to the base station would be inefficient given the energy constraints on the sensor node. This is a result of the data redundancy brought about by nearby sensors' relatively strong correlation. Moreover, base stations are unable to handle the enormous volumes of data produced by a larger sensor network. In order to integrate data and generate meaningful information at sensors or intermediate nodes, specific networks are therefore needed. In this paper, tour path scheduling using optimized deep reinforcement learning (DRL) for MDCs in IoT‐WSN. The DRL algorithm schedules the visiting pattern of the MDCs based on the type of IoT sensors and their data generation rates. To accelerate the convergence speed of DRL, sunflower optimization (SFO) algorithm is used. Then, optimum tour paths are determined using Capuchin Search Algorithm (CapSA) based on path stability and data collection latency. Simulation results have shown that DRL–SFO–CapSA minimizes the data collection delay and packet drop while maximizing the packet delivery ratio and residual energy.
Fuzzy Based Node-to-Node (N2N) and Intercluster Authentication Framework for External Attacks in UWSN Jocil D, R. Vadivel International Journal of Communication Systems, 2025 In underwater wireless sensor networks (UWSNs), there is a need for providing security against internal and external attacks, apart from ensuring reliable data delivery. Due to the high computation cost and the low computing capabilities of UWSN, all present methods of device‐based identity authentication must be performed at the network layer and other layers. The main objective of this work is to protect the data against physical layer attacks using lightweight authentication techniques. In this paper, a fuzzy‐based node‐to‐node and intercluster authentication (Fuzzy‐N2N‐ICA) framework for UWSN has been proposed. Initially, the network is clustered using the minimum average routing path (MARP) algorithm. In N2N authentication technique, the cluster head (CH) collects the network layer and physical layer features from each node. It then determines the deviation index based on these cross‐layer metrics by applying a fuzzy‐logic decision model. Based on the determined deviation index, the corresponding node is authenticated as honest or malicious. In the intercluster authentication phase, each CH creates an authentication key using the secret key obtained from an offline trusted third party. When the aggregated data is received from a source CH, other CHs and the sink node perform authentication. Simulation outcomes have shown that the Fuzzy‐N2N‐ICA framework minimizes the miss detection ratio, authentication time, computational cost, energy consumption, and maximizes the correctness of packet delivery.
Fuzzy-Markov Routing Policy and Priority-Based Load Balancing for Cognitive Radio Ad Hoc Networks S. Sindhuja, R. Vadivel International Journal of Communication Systems, 2025 A cognitive radio ad hoc network (CRAHNs) is an infrastructure‐free network containing a cognitive radio, which can use the spectrum resources effectively through an adaptive change of parameter settings and decision‐making. Hence, it enhances the spectrum efficacy for satisfying the growing mobile traffic requests. In multihop CRAHNs, in order to ensure a reliable transmission and energy efficiency, the routing protocol should consider the metrics of channel quality, link stability, and energy consumption. In this paper, a Fuzzy‐Markov routing policy and priority‐based load balancing algorithm (FMRP‐PLB) for CRAHNs is designed. In this protocol, a combined routing metric is derived using delay, energy rate, and link expiration time metrics. For modeling the channel state, a Fuzzy‐Markov decision model is designed, in which the channel states and spectrum availabilities of SU are modeled as state transition matrices. Then, optimum routing decisions are made using the combined routing metric and the predicted transmission success probability. A load balancing metric (LBM) is derived in terms of available link capacity, remaining buffer size of node, and back‐off delay. During data transmission, based on the traffic priority and measured levels of LBM, the optimum paths are selected. Simulation results using NS2 suggest that FMRP‐PLB attains an increased packet delivery ratio with reduced delay and energy consumption.
Optimizing resource allocation in intelligent communication networks: Fundamentals and challenges S. Mayukha, R.

A Secure Transition Perspective on the Expectations and Benefits of Quantum Networks Over Classical Networks S. Mayukha, R. Vadivel Quantum Computing and Artificial Intelligence the Industry Use Cases, 2025 Quantum computing is the next big thing in information technology. The possibilities of the quantum computing realm are unfathomable. Quantum computing would help humanity perform complex extreme functionalities even faster, better, and more accurately. Right now, there are so many expectations from quantum computing without even understanding the paradoxes of the quantum functionalities. This chapter deals with one such paradox related to quantum networking and its predecessor—classical networks. This also opens up the field of secure communication with safe encryption. The safety of data in the classical network is questionable in a post-quantum computing and networking scenario. The encryptions that are now safe and uncrackable in classical networking would be easy to crack in a post-quantum computing scenario. Since quantum computing helps accelerate the functionalities and its processes, think of a scenario where a password brute forcing that normally takes 3–4 days to complete will be done in 2–3 hours in quantum computing. Every platform would be in danger if quantum computing is mastered by the threat actors before the vendors could provide a quantum-proof way of accessing the content or software. Zero-day exploits would dominate the post-quantum computing time if the proper implementation of encryption, storage, and transmission with safety features is not completed. This would make a similar occasion where the classical computers faced a challenging situation with the Year 2000 Problem (Y2K Problem). The Y2K problem happened because the computers were not ready or taught to cope with the time progression. The classical computers started displaying 1900 instead of 2000. This might seem like a small problem now, but in that milieu, the people panicked and started a computer-induced apocalypse. This mainly happened because there was no clarity on what the future would hold. All the non-experts started misdirecting the management that rectifying the Y2K problem would take billions of dollars. This led to lots of confusion and people stocking up on food and firearms. This caused lots of frenzies and pushed people to the edge of antipathy towards computers. The community now for information technology is proactive. Hence, as a user-centric community, the community must have an amalgamation for post-quantum computing, so that the transition from classical computing to quantum computing is safe, fast, and reliable. This chapter furnishes the challenges of a post-quantum computing scenario from a security perspective and explains the difference and ill effects of transitioning from classical computing and classical networking to quantum computing and quantum networking.
