自动驾驶汽车技术近年来得到了广泛研究与快速发展，但在复杂的交通场景下，自动驾驶汽车面对突然出现的行驶车辆并不能及时避让。针对此问题，基于区块链技术提出智能网联车队的协同轨迹预测系统，智能网联车队中的各个节点与路边基础设施通过长短时记忆网络（LSTM）模型对周边车辆的运动轨迹进行预判，并将得到的结果进行分享，利用区块链技术，智能网联车队与路边基础设施可以对其接收到的信息进行评分，并将汇总后的评分以区块的形式加入存储信誉评分的区块链中。通过该评分，智能网联车队中的车辆可以根据车队中其他节点的信誉值来判断其是否可信，低信誉值节点传来的信息将不予理睬，从而实现了协同驾驶。实验分析表明，所提LSTM模型能够较为准确地预测周边车辆5 s内的行驶轨迹，而所提的系统在提升智能网联车队的行驶安全上起到了明显的效果。

摘  要： 对P2P网络存在的问题进行了分析，阐述了建立P2P网络信任模型的需求。在对现有P2P网络中的信任模型进行总结归纳后，指出了以后研究的方向。对仿真系统进行了性能测试，并对测试结果进行了分析。仿真结果表明，该模型对于信息窃取、信息篡改等类型的恶意攻击有较好的抑制作用。 　　随着P2P系统的广泛应用，安全问题也随之产生。主要体现在以下几个方面：由于共享特性带来的安全问题、中间节点的恶意攻击以及针对P2P系统结构安全漏洞的攻击等。在P2P系统中节点的信息传输往往需要经过多个中间节点的传递，由中间节点产生的威胁最大也最难防范。中间节点恶意攻击包括信息窃取、信息篡改等。 　　随着Interne

People increasingly use social networks to manage various aspects of their lives such as communication, collaboration, and information sharing. A user’s network of friends may offer a wide range of important benefits such as receiving online help and support and the ability to exploit professional opportunities. One of the most profound properties of social networks is their dynamic nature governed by people constantly joining and leaving the social networks. The circle of friends may frequently change when people establish friendship through social links or when their interest in a social relationship ends and the link is removed. This book introduces novel techniques and algorithms for social network-based recommender systems. Here, concepts such as link prediction using graph patterns, following recommendation based on user authority, strategic partner selection in collaborative systems, and network formation based on “social brokers” are presented. In this book, well-established graph models such as the notion of hubs and authorities provide the basis for authority-based recommendation and are systematically extended towards a unified Hyperlink Induced Topic Search (HITS) and personalized PageRank model. Detailed experiments using various real-world datasets and systematic evaluation of recommendation results proof the applicability of the presented concepts.
