Vehicle-mounted net address collocation method based on locating information

Abstract

The invention discloses a vehicle-mounted net address collocation method based on locating information. A vehicle-mounted net comprises access routers, access nodes and vehicle nodes, wherein the access routers are connected onto a backbone network of an internet protocol version 6 (IPV6) internet, one access node can be connected with more than one access router, a rectangle close region surrounded by all access nodes connected with one access router is set to be a road region, and one access node can simultaneously belongs to more than one road region. The vehicle-mounted net comprises more than one road region, wherein a Kth road area is determined according to geographical coordinate intervals of [xk, xk+1] and [yk, yk+1], access nodes in each road region are connected into the IPV6 internet through the access routers, and the vehicle nodes are connected into the IPV6 internet through access nodes of the road region which the vehicle nodes are located on and the access routers.

Description

technical field [0001] The invention relates to an address configuration method, in particular to a vehicle network address configuration method based on positioning information. Background technique [0002] With the continuous development of in-vehicle network technology and the continuous emergence of various new applications, it is urgently required that the in-vehicle network can be connected to the Internet to obtain a network to meet the rapidly growing application needs of users. [0003] The first key technical problem to be solved when the vehicle network is connected to the Internet is the automatic configuration of IPv6 addresses, because vehicle nodes can only communicate with IPv6 network nodes after obtaining a globally unique IPv6 address. Automatic IPv6 address configuration can configure a globally unique IPv6 address for each interface without human intervention. This feature is very consistent with the design goal of self-organization and self-configurati...

Problems solved by technology

For example, the stateful IPv6 address automatic configuration protocol adopts the communication mode of server / client to configure IPv6 addresses. Since configuring IPv6 addresses from remote servers will greatly increase the delay of address configuration, and it is difficult for fast-moving vehicle nodes to assume the role of servers, so , the stateful IPv6 address auto-configuration protocol is not suitable for IPv6 vehicular networks; the stateless IPv6 address auto-configuration protocol uses multicast mode to detect duplicate addresses for the configured IPv6 address through the neighbor discovery protocol to ensure its uniqueness in the network, Due to the long address configuration delay caused by duplicate address detection, the stateless IPv6 address auto-configuration protocol is also difficult to apply to the fast-moving IPv6 vehicular network.
