In this paper, the wireless butterfly-typed network coding scheme is considered. The average packet acquisition time of the wireless network coding scheme is evaluated by theoretical analysis. The effect of the wireless network coding scheme is shown by comparing with the system without network coding scheme. Consequently, it is shown that the wireless network coding scheme is superior to the system without network coding scheme in the reliable channel environment. However, when the distance between nodes becomes longer, the network coding scheme has no effect on shortening of average packet acquisition time.

A traditional parking field is managed by manpower, and perhaps there are also plenty of advanced areas which are auxiliary installed or embedded with IR equipment or marked lines. However, this kind of state is constrained with limit service and bounded. This paper presents an innovative concept of services for parking guidance. Driver can make a reservation by smart phone or tablet pc in thirty minutes before, and furthermore the service platform will book a parking lot using vehicle ID. When vehicle pass through the entrance of parking area, the location of reserved parking lot will be marked in a customized map and transmitted to in-vehicle device using DSRC. After driver parks his vehicle to scheduled parking lot, parking server will send a message to driver or in-vehicle device in order to log the final vehicle location and heading. The developed system, which is named as SmartValet, is also available in underground parking area or interior of the building. The autonomous ability is integrated different sensors to offer robots or remotely operated systems a reliable navigation means. It addresses a global and all weather navigation design based on GPS, gear-box speed, odometry and inertial measurement in dead reckoning and data fusion. Positioning uncertainty will grow with time as a result of integration error so the performance will lose accuracy. To solve this shortcoming with error bounded, this paper uses a creative idea which driver clicks and drags touch panel to give a new position and heading. The proposed system which utilizes DSRC devices, inertial sensors and vehicle network information is implemented with theoretical application and hardware integration, and furthermore the result shows navigation ability and approach applicability.
传统的停车场是由人力管理的,也许也有很多先进的区域辅助安装或嵌入了红外设备或标记线。然而,这种状态受服务限制和有界约束。本文提出了一种创新的停车引导服务理念。司机可以通过智能手机或平板电脑提前30分钟预约,服务平台还会使用车辆ID预约停车场。当车辆通过停车场入口时,预留停车场的位置将被标记在定制地图上,并通过DSRC传输到车载设备。当驾驶员将车辆停到预定的停车场后,停车服务器将向驾驶员或车载设备发送信息,以记录车辆的最终位置和方向。该系统被命名为SmartValet,也可以在地下停车场或建筑物内部使用。自主能力集成了不同的传感器,为机器人或远程操作系统提供可靠的导航手段。它解决了一种基于GPS、齿轮箱速度、里程计和惯性测量在航位推算和数据融合的全球和全天候导航设计。由于积分误差的存在,定位不确定性会随着时间的推移而增大,从而使性能失去精度。为了解决误差有界的缺点,本文采用了驾驶员点击和拖动触摸屏来给出新的位置和方向的创意。利用DSRC器件、惯性传感器和车辆网络信息,对该系统进行了理论应用和硬件集成,结果表明该系统具有良好的导航能力和方法适用性。

Automated container terminal is one of the most important confined areas that have attracted extensive research interests over last decade. To improve productivity, as well as enhance operational efficiency of a sea port, automated container terminals must play an important role in global cargo transportation by saving energy consumption, reducing the service cost and increasing the cargo throughput. To achieve these requirements, the development of reliable heterogeneous communication system among all communicating objects such as Intelligent Autonomous Vehicles (IAV), Confined Base Station (CBS) and RFID-based container that communicate inside container terminals, becomes a paramount objective. This communication system has specific challenges comparing to classical vehicular communication systems ones by emphasizing mainly on IAV-to-IAV, IAV-to-CBS and IAV-to- RFID-based container communications. Our aim in this paper is to introduce the IAV architecture dealing with IAVs based communication system, and then present candidate communication technologies for port container terminals. Further discussions about challenging issues will also be provided.
自动化集装箱码头是近十年来引起广泛研究兴趣的一个重要的受限领域。为了提高生产力,提高海港的运营效率,自动化集装箱码头必须通过节省能源消耗、降低服务成本和增加货物吞吐量,在全球货物运输中发挥重要作用。为了实现这些要求,在所有通信对象之间开发可靠的异构通信系统,如智能自动驾驶汽车(IAV)、受限基站(CBS)和基于rfid的集装箱在集装箱码头内通信,成为一个首要目标。与传统的车载通信系统相比,该通信系统具有特定的挑战,主要强调基于iav到iav, iav到cbs和基于iav到rfid的容器通信。本文的目的是介绍基于IAV的通信系统的IAV体系结构,并提出港口集装箱码头的候选通信技术。还将就具有挑战性的问题进行进一步讨论。

Vehicular Delay-Tolerant Networks (VDTNs) were proposed as a novel disruptive networks based on the delay tolerant networking (DTN) paradigm. VDTN architecture uses vehicles to relay data, enabling network connectivity in challenging scenarios. This architecture uses the store-carry-and-forward parading allowing messages reaching their destination by hopping over nodes. This paper presents an evaluation study performed through a real-world VDTN testbed using two applications: Warning Message and Traffic Jam Information. It also validates the real deploy of this new vehicular communication approach. Because the laboratory environment does not accomplished several complex issues presented in vehicular communication systems, this real testbed is an important contribution. The real deployment of VDTN is confirmed by the results. This deployment is possible and this can be seen as a very promising technology for vehicular communications, although it is required appropriated technologies for outline interferences and quality of service support.
车辆容忍延迟网络(VDTNs)是一种基于容忍延迟网络(DTN)模式的新型中断网络。VDTN架构使用车辆中继数据,在具有挑战性的场景中实现网络连接。该体系结构使用存储-携带-转发巡游,允许消息通过跳过节点到达目的地。本文介绍了一项通过现实世界的VDTN测试平台进行的评估研究,使用了两个应用程序:警告消息和交通阻塞信息。它还验证了这种新型车载通信方法的实际部署。由于实验室环境不能完成车载通信系统中出现的一些复杂问题,因此这个真实的测试平台是一个重要的贡献。仿真结果验证了VDTN的实际部署。这种部署是可能的,这可以被视为一种非常有前途的车载通信技术,尽管它需要针对轮廓干扰和服务质量支持的适当技术。

Taxi service in Taipei Metropolitan is an industry which is full of information asymmetry. Due to taxi service distribution inefficiently, extra supply exists in terms of time and space in service area. In order to decrease the difference of supply and demand, this study proposes a cloud computing based taxi dispatching service- Cloud Taxi. All the driving behaviors are recorded in the system and are transformed into business insight for the taxi driver. Meanwhile, several innovative services are delivered to the end users. Finally, the information generated by Cloud Taxi would be a strong reference for government to foster and manage the industry.

Study of channel selection strategies in cognitive radio networks 认知无线网络中的信道选择策略研究
Pub Date : 2012-11-01 DOI: 10.1109/ITST.2012.6425156
Po-Ying Liao, Bing-Mao Wu, Yen-Wen Chen
The purpose of Cognitive Radio (CR) technology is to improve the spectrum utilization and the spectrum selection is one of the important issues to achieve this objective. In CR environment, many secondary users (SU) share the available spectrum and the SU shall properly select the channel to avoid congestion on the same channel so that the throughput can be maximized. This paper proposes a systematic method to select channel for better transmission performance. A fusion center (FC) is assumed to collect the channel information sent by SUs and decides the channel for the SU that issues the transmission request. The proposed schemes adopt the weight based concept to choose the appropriate channel for the SU. Two strategies, which are the egoistic approach and the cooperative approach, are proposed in this paper to maximize the individual transmission rate and overall system throughput, respectively. Exhaustive simulations were carried out to examine the performance of the proposed schemes. The simulation results show that the proposed schemes have better performance when compared to the other scheme.
认知无线电(CR)技术的目的是提高频谱利用率,而频谱选择是实现这一目标的重要问题之一。在CR环境下,多个辅助用户共享可用频谱,需要合理选择信道,避免同一信道上的拥塞,从而实现最大的吞吐量。本文提出了一种系统的信道选择方法,以获得更好的传输性能。假设FC (fusion center)收集SU发送的通道信息,并为发出传输请求的SU决定通道。所提出的方案采用基于权重的概念为SU选择合适的信道,并提出了两种策略,分别是利己策略和合作策略,以最大限度地提高个体传输速率和系统总体吞吐量。进行了详尽的仿真以检验所提出方案的性能。仿真结果表明,与其他方案相比,所提方案具有更好的性能。

Examining Human Factors for marine casualties using HFACS - maritime accidents (HFACS-MA) 使用HFACS-海事事故(HFACS- ma)研究海上伤亡人为因素
Pub Date : 2012-11-01 DOI: 10.1109/ITST.2012.6425205

A dedicated Human and Organisational Factors (HOFs) framework for maritime accidents analysis is obviously worthwhile to be developed. In this article, a prototype of the framework is proposed and named as Human Factors Analysis and Classification System for Maritime Accidents (HFACS-MA). This is an analogue of HFACS and is in line with the core concepts of Reason's Generic Error Modelling System (GEMS) and Hawkins's SHEL model. Moreover, it complies with the requirements regarding the International Maritime Organization (IMO) guidelines. A proposed analysis method which incorporates HFACS-MA with Why-Because Analysis to provide a comprehensive insight into the accident regarding Herald of Free Enterprise disaster is also demonstrated. This integration may prove beneficial for spotlighting the causalities of the causal factors identified and the vulnerability of the operating system. The reasons that the integration can be deemed as complements to the demographics of a study using HFACS are also discussed in this paper.
一个专门用于海上事故分析的人为和组织因素(HOFs)框架显然值得开发。本文提出了该框架的原型,并将其命名为HFACS-MA (Human factor Analysis and Classification System for Maritime Accidents)。这是HFACS的模拟,符合Reason的通用错误建模系统(GEMS)和Hawkins的SHEL模型的核心概念。此外,它还符合国际海事组织(IMO)准则的要求。本文还提出了一种将HFACS-MA与Why-Because分析法相结合的分析方法,以全面了解“自由企业先驱号”事故。这种集成可能有助于突出所识别的因果因素的因果关系和操作系统的脆弱性。本文还讨论了集成可以被视为使用HFACS进行人口统计研究的补充的原因。

The reasons that the integration can be deemed as complements to the demographics of a study using HFACS are also discussed in this paper.","PeriodicalId":143706,"journal":{"name":"2012 12th International Conference on ITS Telecommunications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122645691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we developed an Unmanned Aerial Vehicle (UAV) image registration system consisting of UAV image to UAV image registration, UAV image to Google satellite image registration, and registration refinement with a normalized variant of mutual information for quality mismatch problem. We show the limitation of the conventional mutual information for quality mismatch and then suggest using a normalized variant of mutual information to refine registration between UAV image and Google satellite image. Experiments carried out on the realistic UAV image sequence and Google satellite image show that the developed system could provide better UAV-to-satellite image registration and could conquer the quality mismatch problem.
本文开发了一种无人机图像配准系统,包括无人机图像与无人机图像的配准、无人机图像与谷歌卫星图像的配准以及针对质量不匹配问题的互信息归一化配准细化。本文指出了传统互信息在质量不匹配方面的局限性,并提出了使用互信息的一种归一化变体来细化无人机图像与谷歌卫星图像之间的配准。在真实无人机图像序列和谷歌卫星图像上进行的实验表明,所开发的系统可以提供较好的无人机图像配准,并能解决质量不匹配问题。
