移动对等网络覆盖网

摘要

The construction of overlays is a crucial problem in the research of mobile peer-to-peer networks.The architecture of overlays determines the robustness,security and performance of MP2P networks.The paper first introduces the concept of mobile P2P overlays,including the definition,significance of the construction of overlays and the classification of them.Next,three kinds of overlays,distributed unstructured,distributed structured and semi distributed (hybrid) network,are described.The application of overlays in MANET,VANET and WMN is especially introduced.Furthermore,the aforementioned overlays are analyzed and compared.Finally,the paper concludes and presents the future research directions.%在移动对等网络的研究工作中,覆盖网络的构造是一个十分关键的核心问题.覆盖网络体系结构决定了移动对等网络的健壮性、安全性和性能.首先提出移动对等覆盖网络的概念,给出了其定义、构建覆盖网的重要意义和覆盖网的分类.然后阐述了3类不同的覆盖网,即分布式非结构化网络、分布式结构化网络和半分布式(混合式)网络,其中特别论述了这些覆盖网在移动自组网、车辆自组网以及无线Mesh网络等方面的应用,并进行了分析和比较.最后,对整个移动对等覆盖网络研究工作进行了总结,并对下一步研究方向进行了展望.
