中文摘要： 车联网是以车辆为主要节点、按自组织方式组成的移动无线通信网络。基于车联网及相关技术(如传感器技术、智能处理技术等)，可以感知和传递车辆及环境信息，进而可以实现多种应用，包括车辆主动安全、智能交通管理、物流管理、城市生活服务、紧急救援等，应用前景广阔。鉴于不少车联网应用本质上是基于事件的分布式系统，本项目拟研究车联网环境中的事件检测和分发技术，为车联网环境中基于事件的决策提供新见解、新思路、新方法。针对车联网通信的时变性和随机性以及车联网上事件流的多样性和演化性带来的挑战，本项目将重点研究时空事件流中具有指定事件模式的实时事件检测技术、异常和关联模式的早期捕获技术、不同车联网场景下的事件分发算法、及其基于跨层协作的服务质量提供及优化算法，同时，构建车联网模拟实验平台，进行技术测试和评估，实现车联网事件服务原型，方便车联网应用的开发。项目的研究成果将促进车联网及其应用的发展和推广。

英文摘要： Vehicular ad hoc networks (VANETs) are a kind of mobile wireless communication network where the vehicles, as main nodes, communicate with each other in an ad-hoc way. A lot of information related to vehicles and/or environments can be sensed and delivered over VANETs with the aid of other technologies (e.g., sensor sensing and intelligent processing, etc.). Such kind of platforms enable a variety of promising applications (such as vehicle active safety, intelligent transport management, logistics management, city life services, emergency assistance, etc.) to be implemented. Considering that most VANET applications are event-based distributed systems in nature, this project plans to conduct the researches on event detection and dissemination over VANETs so as to provide novel insights, ideas and approaches to supporting event-based decisions. Facing with the challenges brought by time varying and stochastic characteristics in VANET communication and diversification and evolution in event streams, this project will focus on the following topics: real-time detecting the events with specified patterns and early capturing the outliers and association patterns from spatio-temporal event streams, disseminating events under different VANET scenarios, providing and optimizing quality of services of data delivery by cross-layer cooperation. Meanwhile, the project will build a platform for VANET simulation experiments by which the proposed technologies are evaluated and tested, and implement a VANET event service prototype to facilitate the development of VANET applications. The research results are expected to promote the development and popularity of VANETs and their applications.
