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 the 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 large, and the mobile handover delay is long, which increases the packet loss rate

Embodiment 1

[0121] Based on the simulation parameters in Table 1, this embodiment simulates the mobile handover method of the vehicular network in the present invention, and the performance analysis is as follows: when the vehicle density is constant, as the speed of the vehicle node increases, the vehicle node performs mobile handover As the probability increases, the link stability weakens, so the delay and cost of acquiring mobile handover increases accordingly. The average delay of mobile switching of vehicle nodes is 10ms, and the average cost is 800byte.

Abstract

The invention discloses a mobile switching method of a vehicular network. The vehicular network comprises an access node and a vehicle node and accesses the Internet via more than two access routers. By means of the mobile switching method provided by the invention, the vehicular network can keep the communication continuity in a moving process, shorten the mobile switching delay and reduce the data packet loss rate, so that the quality of service of the vehicular network is improved, and the mobile switching method provided by the invention can be applied to road condition monitoring, vehicle management and other fields, thereby having a wide application prospect.

Description

technical field [0001] The invention relates to a system for realizing mobile handover, in particular to a mobile handover method for a vehicle-mounted network. Background technique [0002] Due to its practicability, VANET has received widespread attention and has become a research hotspot. One of the main features of VANET is that vehicle nodes move at high speed along the road. Therefore, how to realize seamless mobile handover of vehicle 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 urban vehicle networks. 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 the 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...
