Abstract

The invention provides an urban vehicle-mounted network moving switching method based on IPv6 (Internet Protocol Version 6). An urban vehicle-mounted network comprises a boundary router, an access router, access nodes and a vehicle node, wherein the boundary router serves as the boundary router of the urban vehicle-mounted network to be connected with a backbone network of the internet; the whole urban vehicle-mounted network is covered by all the access nodes, and all the access nodes are connected with one access router; the access router is connected into the internet through the boundary router; and the vehicle node is connected into the internet through the access nodes within an one-hop range.

Description

technical field

[0001] The invention relates to a mobile switching method, in particular to an IPv6-based urban vehicle network mobile switching method. Background technique

[0002] With the continuous maturity and development of the next-generation network (IPv6 network), the urban vehicle network based on IPv6 has become an inevitable trend of future development. One of the main features of VANET is that vehicle nodes move along the road. Therefore, how to realize the seamless mobile handover of vehicle nodes has become one of the research hotspots.

[0003] Due to the different architectures of the vehicular network and the IPv6 network, it is difficult for the mobile protocols in IPv6 to work effectively in the vehicular network. Therefore, how to realize low-latency vehicular network mobile handover has become an important problem that needs to be solved urgently. Contents of the invention

Embodiment Construction

[0046] The invention provides an IPv6-based urban vehicle network mobile switching method, and the realization method can be widely used in the urban vehicle network. In the vehicular network, the vehicle nodes are highly mobile, so the packet loss rate will be caused in the mobile handover, thereby degrading the communication quality. The invention shortens the mobile switching delay of the vehicle node and reduces the packet loss rate of the vehicle node. Through the present invention, the vehicle node can better obtain Internet network services, such as video and audio, etc. during the moving process.

[0047] figure 1 It is a schematic diagram of the topology structure of the IPv6-based urban vehicular network according to the present invention. The urban vehicular network includes a border router 1, an access router 2, an access node 3 and a vehicle node 4; wherein, the border router 1 is connected to the backbone network of the Internet as a border router of an urban v...
