NDN-VANET

以下是关于NDN在VANET方面的论文笔记。

Named Data Networking in VANET: A Survey

问题: Short connection and dynamic topologies 

工具: ndnSIM

解决方法: ndnSIM 中的 network caching, security, and data availability

挑战1: Distributed storage in every node of network and lesser cache space which decrease the success rate of data and overhead is introduced in cache management

解决1: HCC, which is grouping network into cluster, for each cluster one clusterhead is selected for all the cluster, this clusterhead manage all disicion in one cluster

挑战2: Security

解决2: By providing security at data level this is provided by security layer for securing data in NDN

挑战3: Mobility

解决3: Different technique is used to achieve this mobility such data mulling physical carries of data in case intermittent. This technique mainly used for sparse vehicle and the other technique is multi hop technique mainly used for dense vehicle

挑战4: Efficient data dissemination

解决4: Different forwarding strategies

仍需要解决的问题: naming, mobility, forwarding(DPIT), interest flooding

RUFS: RobUst Forwarder Selection in Vehicular Content-Centric Networks

 问题:interest/data flooding, consumer/provider mobility

工具/方法:RobUst Forwarder Selection(RUFS),每一个vehicle分享自己已经被满足的interest包的数据给邻近vehicle,全部的邻近结点将这些信息存储在NSL(Neighbors Satisfied List), 帮助选择潜在的兴趣转发者,

效果:缓解兴趣广播风暴

CODIE: Controlled Data and Interest Evaluation in Vehicular Named Data Networks

问题: 消费者和提供者的移动性,兴趣包和数据包的转发

工具/方法: 将NDN这种data沿着interest的路径返回的传输模型运用在车载自组网(VANET)中;使用CODIE来解决数据包泛洪或广播风暴(消费者在兴趣包中启动一个跳数计数器,在潜在提供者接收到兴趣包后,数据传播限制值(DDL)会存储跳数,并且一个数据包需要根据DDL返回)

效果:处理的数据包的个数(CDPP)减少;兴趣包满足率无明显变化(ISR);减少了总体的兴趣包满足延时(ISD)
  • A New ICN routing selecting algorithm based on Link Expiration Time of VANET under the highway environment

    工具/方法: 新的FIB,选择基于链接满期时间的有效内容录用(ECRMLET)。

DT-ICAN: A Disruption-Tolerant Information-centric Ad-Hoc Network

 问题:ICN应用在高频受损的VANET上所引起的问题

工具/方法:DT-ICANSIM(DT-ICAN的仿真器)

效果:提高了文件的检索率
