PMIPv6的移动自组织网络邻居节点的快速发现机制研究

Research of Neighbor Nodes Fast Discovery Mechanism in VANETs Based on Proxy Mobile IPv6

为有效改善车辆道路安全、降低交通拥塞,采用移动自组织网络使路网中的各车辆所采集的交通信息能与周边其他车辆共享,是智能交通系统中常用的技术方案。由于交通信息与车辆地理位置有高度的相关性,但目前网络中每个移动节点并没有地理位置资讯,在应用层中无法有效区分移动节点的地理位置。文章提出一种基于IPv6移动代理协议(Proxy Mobile IPv6,PMIPv6)邻居节点的快速发现机制,对每个移动节点在注册/切换后可以快速找寻到邻近的移动节点,并通过该机制的节点注册切换、注册切换所需网络延迟、以及Binding Cache更新所需成本进行性能分析,能有效解决移动自组织无线网络中移动节点快速识别邻居节点的问题。

In order to effectively improve the road safety and reduce traffic congestion,sharing the road network data with others surrounding vehicles are often used in the intelligent traffic system.Because the traffic information is highly correlated with the location of the vehicle,there is no location information of each mobile node in the network,and the location of the mobile node can't be distinguished in the application layer effectively.This paper proposed a mobile agent based on IPv6(Proxy Mobile IPv6,PMIPv6)the rapid discovery mechanism of neighbor nodes for each mobile node in the registration/switch can quickly find neighboring mobile nodes,and the nodes registered cost switching,the mechanism of the registration required to switch the network delay,and the Binding Cache update required the performance analysis,could effectively solve the problem of mobile ad hoc wireless networks mobile rapid identification of neighbor node problem.
