We address these challenges by developing a Zero Trust Authentication Protocol for Inter-Satellite Link (ISL) communication. Our protocol implements a novel verification process that leverages orbital signals to authenticate ISLs. This approach ensures secure data access and transmission exclusively among verified satellites, mitigating threats from eavesdropping, signal spoofing, impersonation, and replay attacks. To optimize security and resource efficiency, we integrate Hyperelliptic Curve Cryptography (HECC) into our protocol.

Also, user quality of service (QoS) requirements and interference between ABSs and GBSs require meticulous management during the user association process for effective load balancing. In this paper, we propose a new joint ABS placement and user association scheme based on a whale optimization algorithm (WOA) for throughput maximization and load balancing in aerial–terrestrial networks.

Also, a QoS-aware greedy user association algorithm that maximizes the load balancing utility function is developed to facilitate the fitness evaluation of each whale.

However, these networks face challenges such as spectrum leakage and the limited power capacity of IoT devices. Merging cognitive radio (CR) technology in these networks is a potential solution to mitigate the challenge of the insufficient frequency spectrum. In this paper, we consider a scenario of two secondary users (SUs) accessing a CR network with a single primary user (PU) within the interweave/underlay access scheme. The SUs have two heterogeneous traffic: status update packets and deadline-constrained packets, which are measured using the age of information (AoI) and the timely throughout metrics, respectively. To address the energy limitation issue, an adaptive power allocation strategy for the SUs’ transmissions is initially developed. Subsequently, we investigate the trade-off between power consumption for the secondary system and specific demands of each traffic type independently. A stochastic optimization problem is then constructed to minimize the weighted sum average power consumption of the secondary system while ensuring a maximum average AoI threshold and an average minimum timely throughput per frame requirement for the corresponding SUs. The Lyapunov optimization theory is employed to convert the formulated problem into an unconstrained Markov decision process (MDP) per frame. Moreover, we derive a formula for the outage probability of SUs’ transmissions, considering the presence of multiple primary receivers. Simulation results demonstrate how the total consumed power is affected by the variations in the key system parameters, such as the activity and transmission power of the PU. Furthermore, experimental simulations show that the proposed policy achieves significant enhancement over two baseline policies.</div></div>","PeriodicalId":55555,"journal":{"name":"Ad Hoc Networks","volume":"174 ","pages":"Article 103833"},"PeriodicalIF":4.4,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143715417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current scholarly work predominantly focuses on the tight binding of tasks and platforms to meet the real-time and deterministic requirements of CPPS, but does not fully utilize the flexibility and customization characteristics of CPPS. Therefore, there is an urgent need for intelligent and flexible task platform decoupling in the future to meet various quality of service (QoS) requirements such as flexibility, energy consumption and real-time performance, which also brings the challenge of meeting CPPS requirements. To address this issue, this work studies the decoupled flexible manufacturing dynamical scheduling problem with the aim of jointly optimizing real-time performance and energy consumption. Firstly, a multi-priority feedback queue is designed, which can dynamic adjust priority to ensure real-time performance of tasks. Subsequently, multi-objective optimization models are used to allocate network and computing resources for tasks, taking system latency and energy consumption into account as costs. To narrow the solution space and improve solving speed, a locally optimal resource allocation method is derived. Furthermore, scheduling algorithms for the end-side and edge-side are designed separately. On one hand, considering the energy sensitivity of edge devices, a lightweight scheduling algorithm called terminal double deep Q network (T-DDQN) has been proposed to quickly determine the optimal task execution location. On the other hand, a task offloading strategy named game theory edge device-level task offloading (GTETO) has been introduced to address the load imbalance issues at the edge caused by T-DDQN. Compared to existing algorithms, it can reduce system cost by up to 25.26%, and improve resource utilization of edge devices by 8.34–27.77%.</div></div>","PeriodicalId":55555,"journal":{"name":"Ad Hoc Networks","volume":"173 ","pages":"Article 103831"},"PeriodicalIF":4.4,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, for a proper RAT selection, this paper proposes a novel hybrid and adaptive approach based on Deep Reinforcement Learning (DRL) that combines QoS and Quality of Experience (QoE) factors. Unlike previous research, our approach integrates QoS parameters and an adaptive network trust factor that reflects the user's QoE based on reliable past device experiences, ultimately providing users with consistently better connectivity. Within our framework, an IoT device dynamically selects its RAT in a distributed manner based on service requirements and the trust score it assigns to RATs, reflecting its satisfaction with past RAT behavior. The proposed hybrid and adaptive RAT selection approach meets QoS requirements, for various applications at any time as indicated by simulations run using Network Simulator 3 (NS3). Compared to other methods, the energy consumption was reduced by 64.12%, network handovers were decreased by 37.73%, while the average packet delivery ratio was improved by 17.85%.

In addition, the intra-cluster multi-hop strategy is used to solve the problem of CHs moving away from the cluster center due to intra-cluster rotation. For inter-cluster communication, the CH selects the most energy-efficient relay node by measuring the distance to other CHs through RSSI.
