In this paper, we propose a hybrid Device-to-Device (D2D) communication framework that combines BC with Active Transmission (AT), where devices can make intelligent decisions to switch between modes based on distance, channel, and energy conditions. By jointly optimizing device associations, backscatter coefficients, load, and time allocation, the system maximizes energy efficiency while meeting delay, energy, and task requirements. Meanwhile, considering that selfish device behaviors may hinder collaboration, we design a payment mechanism based on resource-sharing benefits, incorporating social relationships to incentivize devices to actively participate in cooperation. Additionally, we propose a Multiagent Deep Deterministic Policy Gradient algorithm in the D2D hybrid communication network to solve the long-term joint optimization problem, enabling devices to dynamically adjust offloading strategies and construct optimal D2D links.

Vehicular Edge Computing (VEC) addresses these challenges by leveraging computing resources on moving vehicles, but ensuring information timeliness remains problematic due to network dynamics and resource constraints. This paper proposes a novel multi-agent scheduling framework that utilizes Age of Information (AoI) as the primary metric to maintain data freshness in VEC environments. Unlike conventional approaches that focus solely on latency reduction, our strategy employs a distributed multi-agent architecture where vehicle-mounted servers collaborate through limited information exchange to make coordinated scheduling decisions. We develop a hybrid optimization model combining game theory and reinforcement learning that enables agents to balance individual and collective objectives while adapting to vehicular mobility patterns. The scheduling mechanism operates across three dimensions: spatial (server selection), temporal (execution timing), and priority-based (task importance). Simulation results using real-world urban traffic datasets demonstrate that our approach reduces average AoI by 37 % compared to centralized scheduling methods, while improving computational resource utilization by 42 % and decreasing communication overhead by 29 %.

Deploying access points at the edge of the network significantly reduces the propagation distance of sidelink messages, resulting in very low latencies. However, urban environments pose significant challenges, as numerous obstacles can block direct links between devices and their intended destinations. While the typical fallback solution is cellular connectivity, the difference in performance is substantial. To address this, the present work puts forward solutions for improved reliability in multiple Radio Access Technology urban vehicular architectures. On the one hand, we address situations where multiple links are available, by establishing a make-before-break vertical handover scheme for optimized radio interface selection, monitoring the performance of received packets. On the other hand, we also reflect on the situations where communication ranges are shortened, and thus propose a method where packets sent via Cellular-Vehicle-to-Everything (C-V2X) sidelink are relayed. Here, the initial message is received by an intermediary with better connectivity to the target access point and then retransmitted from this improved position. These solutions have yet to be studied in real-life urban testbeds. We thus present experimental campaigns aimed at exploring the performance and reliability of such communications in urban V2X architectures, exploiting C-V2X, 5G, autonomous vehicles and state-of-the-art hardware. We study multiple scenarios, extending or shortening line-of-sight situations to analyze coverage and performance. Performance analysis of our vertical handover solution shows a reduced usage of cellular connectivity, leading to a 27% reduction of packet latency. Then, relayed C-V2X packets show high reliability at up to 200-meter ranges from one peer to another, with observed latencies being, at worst, 42% more favorable than the cellular fallback.</div></div>","PeriodicalId":55555,"journal":{"name":"Ad Hoc Networks","volume":"179 ","pages":"Article 104007"},"PeriodicalIF":4.8,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145050106","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 massive volume of sensing and communication data in IoV systems challenges traditional cloud computing with latency and energy overload. While multi-access edge computing (MEC) mitigates latency by moving computation to the network edge, its limited coverage remains a bottleneck. Integrated Sensing and Communication (ISAC) further enhances vehicular awareness by enabling real-time environmental perception.

Specifically, within the same community, a heuristic function optimizes routing paths between source and destination nodes. For inter-community message forwarding, a community proximity metric is introduced to evaluate a node’s interaction density with the target community. This metric serves as an encounter-driven heuristic function to identify the shortest inter-community routing path.

Extensive experiments using both simulation scenarios and real-world datasets were conducted to validate the effectiveness of HCAR.

However, the inherent characteristics of Low Power and Lossy Networks (LLNs), including limited energy resources, constrained memory and processing capabilities, high packet loss rates, and dynamic network topologies, make RPL highly susceptible to control plane disturbances. Among these, multicast DIS flooding attacks are particularly damaging, as they repeatedly trigger Trickle timer resets across multiple neighbors, causing excessive control message propagation, severe energy depletion, and routing instability. Existing countermeasures often require protocol modifications, incur high overhead, or fail to discriminate between normal and malicious multicast DIS patterns in dynamic environments. Motivated by these challenges, this work proposes DIS-FDM, a lightweight, fully distributed detection and mitigation scheme for multicast DIS floods. DIS-FDM employs Dempster-Shafer theory (DST) to fuse evidence from local DIS traffic load and parent change frequency, allowing accurate attack detection without altering core RPL functions.
