Embodiment Construction

[0037] The technical solution will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] The present invention provides a message dissemination method for combining the sociability of vehicles in the Internet of Vehicles, considering how to optimize the selection of forwarding nodes in an area given a limited deployment budget, so as to maximize the number of successfully delivered messages. In the process of forwarding node selection, for the goal of maximizing the number of successful message delivery, select nodes with high contact rate and high cooperation degree as much as possible. Finally, a greedy algorithm is proposed in combination with the sociability of vehicles. In each step of the selection process, candidate nodes with high contact rate and high degree of cooperation are selected as much as possible. And it is proposed that the node with a higher ratio of contact probability and cooperation degree is preferred to fo...

Abstract

The invention provides a message propagation method combining the sociability of vehicles in the Vehicular Ad-hoc Network. The message propagation method is characterized by comprising the steps: vehicle GPS trajectory data is collected, and a community structure is mined; the contact probabilities among nodes are solved according to vehicle contact information, and the community cooperation degrees of the nodes are obtained according to the request message numbers and forwarding message numbers of the vehicles; and the contact probability and community cooperation degree between a source nodeand a target node are compared with the contact probability and community cooperation degree between a contact node and the target node, the nodes with the high contact probability and the high community cooperation degree are added onto a candidate set, and the node with the highest contact probability to community cooperation degree ratio is selected from the candidate set to serve as a forwarding node. According to the message propagation method, the reality situation can be well simulated, an effective solution is reasonably provided for the sociability of vehicle movement, message forwarding can be more reasonable and efficient, and resource waste is avoided.

Description

technical field [0001] The invention relates to the field of resource deployment of the Internet of Vehicles, in particular to a method for disseminating messages combined with the sociability of vehicles in the Internet of Vehicles. Background technique [0002] Vehicle Ad-hoc Network (VANET), referred to as the Internet of Vehicles, is a wireless communication network used for vehicles to exchange information within a certain communication range. With the development of the Internet of Vehicles, there have been more and more studies on message transmission. Message transmission is a difficult problem in VANET. A message starts from the source node and passes through multiple relay nodes before reaching the destination node. In this process, the relay node, that is, the forwarding vehicle, plays a vital role. In this network, there are many types of vehicles, mainly divided into two categories: private vehicles (private cars, etc.), public vehicles (buses, taxis, etc.). ...
