title: Wireless communication performance based on IEEE 802.11p R2V field trials abstract: 摘要： Next-generation telematics solutions are being driven by the maturation of recently deployed intelligent transportation systems, assisted by the integration of and rapid collaboration with information communication technology markets and the automotive industry. Examples of this trend can be found in DSRC contexts in which Wi-Fi and WiMAX have become very relevant in vehicular environments. Comprehensive field trials were conducted and relevant measurements were collected in physical environments to investigate the possible environmental factors that occur in roadside-unit-to-vehicle communication scenarios. In these carefully controlled automobile experiments, the most representative parameters are measured and analyzed for DSRC in dynamic environments (e.g., packet loss, latency, and delay spread). Using a systematic testing procedure and through measurement analysis, the communication performance and the operating reliability of wireless communications can be effectively verified; insightful improvements and helpful suggestions and contributions may thus be achieved for telematics system designs. Furthermore, a practical, reasonable, and standardized testing procedure is proposed, and it can be utilized in equipment verification and product certification. 其他題名： COM-M 出版者： New York: IEEE 出版日期： 2012-05-01 出處： IEEE communications magazine, 2012-05, Vol.50 (5), p.184-191 資源來源： IEEE Xplore (NTUSG) 版權： Copyright The Institute of Electrical and Electronics Engineers, Inc.

Video-Quality-Driven Resource Allocation for Real-Time Surveillance Video Uplinking Over OFDMA-Based Wireless Networks

Thu, 23 Apr 2026 05:10:56 GMT

title: Video-Quality-Driven Resource Allocation for Real-Time Surveillance Video Uplinking Over OFDMA-Based Wireless Networks abstract: 摘要： This paper proposes an effective real-time video uplink (UL) framework for mobile wireless camera networks (WCN) over an orthogonal frequency-division multiple access (OFDMA), based infrastructure. Mobile wireless camera stations (CSs) transmit their videos in real time to a base station (BS) so that these live video streams can be archived or fed to subscribers to facilitate real-time video monitoring. Based on the utility function driven by video quality, the target bit rate resulting in the highest possible utility is quickly set for each UL video. To optimize system performance, a real-time video packet scheduler and a spectral-efficient resource-allocation policy are derived. This scheduler is also capable of exploiting the inherent diversity gain due to channel variations. Using fourth-generation (4G) mobile network protocols and a realistic wireless channel model, it is demonstrated through our extensive simulations that our proposed method can significantly enhance utility, boost spectral efficiency, and stabilize video quality. 其他題名： TVT 出版者： New York: IEEE 出版日期： 2015-07-01 出處： IEEE Transactions on Vehicular Technology, 2015-07, Vol.64 (7), p.3233-3246 資源來源： IEEE Electronic Library (IEL) 版權： Copyright The Institute of Electrical and Electronics Engineers, Inc.
