Example Embodiment

[0041] like figure 1 As shown, a prototype system for tolerant traffic information dissemination based on Android, the system provides 14 functions, the specific description is as follows:

[0042] (1) Information classification. Classification according to the information content.

[0043] (2) Message encapsulation. Obtain geographic information and traffic information collected by the system, and then encapsulate them into messages in a specific format.

[0044] (3) News release. After a node generates a message, the node needs to determine which regions the message is valuable for based on its message type, message content, current geographic location information, etc., so as to designate these regions as message destinations.

[0045] (4) News subscription. The user does not need to know the traffic information irrelevant to him. Through this function, users can set the type of messages to focus on, so as to complete the subscription of traffic information.

Abstract

An interrupt-tolerant traffic information spreading prototype system based on Android is divided into three layers. Firstly, the hardware interface layer is responsible for point-to-point communication between vehicles and used for collecting traffic information and geographic information. V2V communication is achieved by adopting the Wifi-Direct technology, and then a self-organizing network is built. Secondly, a network layer is responsible for forwarding and caching traffic messages and analyzing and repackaging the messages. The DTN technology is introduced in, the traffic information is spread in a vehicle network through a storage-carrying-forwarding routing strategy, and the communication interrupt problem caused by link topological structure dynamic changes of the vehicles is effectively solved. Thirdly, an application layer is used for packaging, analyzing and displaying the traffic messages. On the basis of a subscription and publication mechanism of message content, a message delivery destination is selected more reasonably, network loads caused by message copy are reduced, and user experience is optimized through message filtering.

Description

technical field [0001] The invention relates to the fields of computer network, delay-tolerant / break-tolerant network, intelligent traffic system, and Internet of Vehicles, in particular to an Android-based prototype system for disseminating fault-tolerant traffic information. Background technique [0002] The Intelligent Transportation System (ITS for short) is the development direction of the future transportation system. It effectively integrates advanced information technology, data communication transmission technology, electronic sensor technology, control technology and computer technology, etc. It is a real-time, accurate and efficient integrated traffic management system established by the traffic management system that plays a role in a wide range and in an all-round way. [0003] The Internet of Vehicles is an important application of the Internet of Things technology in the intelligent transportation system, and it is a concentrated expression of the application ...
