Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings;

[0029] Reference figure 1 , The vehicle network includes roadside equipment j and its communication range R j The internal vehicle nodes, the vehicle nodes realize information interaction through the communication between them and the roadside equipment, and the configuration of the roadside equipment can realize seamless coverage of all roads;

[0030] Reference figure 2 In the vehicle network, the steps of the method for allocating time slots with guaranteed service delay requirements include the following:

[0031] Step 1. Each roadside device measures the number of vehicle nodes N in its communication range j, t , The speed of each vehicle node S j, i, t And position P j, i, t , And inform other roadside equipment;

[0032] 1.1 When the i-th vehicle node enters the communication range R of the roadside device j at time t j When inside, mark the vehicle node as...

Abstract

The invention discloses a time slot allocation method for guaranteeing business time-delay requirement in a vehicle network, mainly aiming at solving the problem that the existing method can not give consideration to the time-delay requirement of the business and the maximization of the network throughput capacity at the same time. The time slot allocation method comprises the following realization steps of: measuring the quantity, the speed and the position of vehicle nodes within the communication range of roadside equipment by the roadside equipment; judging whether the sum of the communication time delay, the vehicle nodes speed and the all grouping arrival speed between the vehicle nodes and the roadside equipment meets a corresponding condition or not by the roadside equipment; adding the vehicle nodes which meet the condition into a scheduling list, computing the time-delay sensitive factor of the business, and the time slot quantity allocated for the business; allocating the residual time slots when no new business is available for the vehicle nodes if the roadside equipment further has the unallocated scheduling time slots; and stopping the time slot arrangement of the scheduling cycle by the roadside equipment. According to the time slot allocation method, the time-delay requirement of the business can be guaranteed, the maximization of the time slot use ratio can be realized, and the fairness can be considered at the same time.

Description

Technical field [0001] The present invention belongs to the field of communication technology, relates to multiple access technology, and further relates to a time slot allocation method based on time slot utilization efficiency for the purpose of ensuring service delay requirements, which can be used for vehicle nodes and roadside equipment in vehicle networks Communication between. Background technique [0002] In the vehicle network, each vehicle node plays an important role in the intelligent transportation communication system through autonomous calculation and mutual communication. With the assistance of roadside equipment, nodes can provide each other with information such as traffic status, regional weather, driving safety warnings, and scenery pictures. However, due to the high-speed mobility of nodes and the time delay limitation of application services, how to ensure that the vehicle node successfully obtains the service time slot of the roadside equipment within the ...
