Problems solved by technology

Each node in the suspension area generally uses flooding to forward suspension information, but due to network instability and node differences, when some nodes need to update the current suspension information, and flood update information to other nodes in the suspension area , may lead to inconsistencies in the information of some nodes in the suspension area, how to quickly converge and ensure the consistency of the suspension information of each node in the area is a challenging problem

Embodiment 1

[0041] The method in VANET based on the content consistency of the two-stage submission of suspension information includes the following steps:

[0042] (1) Use the floating information cache stack to store the floating information

[0043] After the node enters the anchor area, it will automatically allocate a cache stack with the same size as the number of nodes in the anchor area. This stack is a cache stack sorted according to the timestamp of the information, and the latest timestamp is at the top of the stack; through the cache The stack can cache the suspension information forwarded by different timestamps; if the node leaves the anchor area, the contents of the cache stack will be automatically cleared;

[0044] The timestamp is automatically assigned by the current node when an update needs to be submitted. At this time, the timestamp is the global time in the anchor zone accurate to milliseconds, ensuring the uniqueness of the timestamp and avoiding information confl...

Abstract

The invention belongs to the technical field of mobile communication and discloses a two-stage submit based suspension information content consistency method in a VANET (vehicular ad-hoc network). Aiming at the problem of suspension information consistency in the VANET, a two-stage submit based content consistency strategy is adopted, information storage is realized by the aid of ordering cache stacks, information transmission is realized by means of deviation based probabilistic flooding, and nodes go through two stages including determining whether a submit permission is provided or not according to a timestamp and determining whether information updating is carried out or not. The two-stage submit based suspension information content consistency method in the VANET has the advantages that by the aid of the suspension information in the VANET, sharing of information such as road safety and the like in specific areas can be realized; by adoption of the two-stage submit based content consistency strategy, convergency rate and network data packets are reduced to a great extent while information content consistency is well guaranteed, and consequently a driver is enabled to timely know road conditions beyond a visual range so as to realize safe driving.

Description

technical field [0001] The invention belongs to the technical field of mobile communication. Aiming at the consistency problem of suspended information in VANET (Vehicular Ad-hoc Network, VANET), a content consistency strategy based on two-stage submission is proposed, information is stored by means of a sorting cache stack, and a bias-based The probabilistic flooding method of mobility forwards information. Nodes go through two stages. First, they decide whether they have permission to submit according to the timestamp, and then decide whether to update the information. The advantage of the present invention is that under the multi-vehicle situation of VANET, the content consistency strategy based on the two-stage submission is adopted (as shown in the accompanying drawing of the description) figure 2 is the consistency strategy scenario representation diagram), which can greatly reduce the convergence speed of nodes and the number of data packets in the network, while ensuri...
