Implementation method for mobile handover of vehicle network

Abstract

The invention discloses an implementation method for mobile handover of a vehicle network. The method is characterized in that three types of nodes including access routers, access nodes and vehicle mobile nodes are set in the vehicle network; and the access nodes are connected with the access nodes of an IPv6 internet, the vehicle mobile nodes are accessed into the IPv6 internet through the access nodes related thereto, and neighboring vehicle mobile nodes are in communication. With the mobile handover method provided by the invention, continuity of communication in a moving process can be maintained, delay of the mobile handover is shortened and loss rate of data packets is reduced, so that service quality of the vehicle network is improved; and the method provided by the invention can be used in the fields of road condition monitoring, vehicle management and the like, and has wide application prospects, so that the technology has greater promotional value.

Description

technical field [0001] The invention relates to a system for realizing mobile handover, in particular to a method for realizing mobile handover of a vehicle network. Background technique [0002] Due to its practicability, VANET has received widespread attention and has become a research hotspot. One of the main characteristics of VANET is that road mobile nodes move along the road. Therefore, how to realize the seamless mobile handover of road mobile nodes has become one of the research hotspots. [0003] At present, there are still some problems in the application of existing mobile protocols (such as HMIPv6, FMIPv6 and MIPv6) to the vehicle network. The main reasons are as follows: [0004] 1) In the existing mobile protocol, the mobile node needs to send and receive a large amount of control information to ensure smooth communication during the movement and reduce the loss of data packets, and the transmission of control information will consume a lot of energy, which w...

Problems solved by technology

[0004] 1) In the existing mobile protocol, the mobile node needs to send and receive a large amount of control information to ensure smooth communication during the movement and reduce the loss of data packets, and the transmission of control information will consume a lot of energy, which will greatly reduce the number of mobile nodes. life span;

[0005] 2) The control information packet overhead of the existing mobile protocol is relatively large, and the mobile switching delay is long, which increases the packet loss rate
