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}

However, the increasing number of IoT devices utilizing various Radio Access Technologies (RATs), each with distinct communication requirements, presents significant challenges in ensuring reliable Quality of Service (QoS) in such a heterogeneous, multi-technology, multi-user, and multi-application environment. 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%. This demonstrates the effectiveness of the proposed approach in optimizing both energy efficiency and network performance, ensuring a more reliable and sustainable system for IoT applications.</div></div>","PeriodicalId":55555,"journal":{"name":"Ad Hoc Networks","volume":"174 ","pages":"Article 103838"},"PeriodicalIF":4.4,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143715418","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}

In this paper, we propose an intra-cluster multi-hop based CH rotation (ICMH-CHR) protocol for WSN. This protocol sets two thresholds based on the average residual energy in the cluster. These thresholds are used to dynamically regulate the network re-clustering and CH rotation strategies, respectively, to reduce the number of network re-clustering and avoid the premature death of CH nodes. 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.

For this purpose, we propose a clock, noise, and multipath error characterization for each localization system to perform a realistic comparison over multiple industrial scenarios where Autonomous Mobile Robots freely navigate. In order to ensure a fair comparison, a sensor distribution optimization has been carried out for attaining the best achievable performance of each analyzed system. Results show that the selection of the best localization system may depend on the scenario and application conditions as well as the deployment budget.

Without a cognitively inspired framework, effectively managing this complex data becomes increasingly difficult. The behaviour of the data stream should be cognitively assessed in a number of scenarios to ensure that CIoT applications continue to operate smoothly and exhibit non-chaotic behaviour.
