Embodiment 1

[0059] Such as figure 1 As shown, this embodiment provides a time slot allocation method, the method comprising:

[0060] Step S110: According to the geographic location, the vehicle-mounted devices that have not obtained time slots in the target area are divided into N game groups; the N is an integer not less than 2; each group includes at least one of the vehicle-mounted devices;

[0061] Step S120: selecting one vehicle-mounted device as a game participant for each game group;

[0062] Step S130: Determine the strategic space for each game participant to participate in the i-th time slot game;

[0063] Step S140: game each of the game participants according to the strategic space, and solve the game result to obtain a Nash equilibrium solution;

[0064] Step S150: According to the Nash equilibrium solution, allocate the ith time slot to the corresponding game participants.

[0065] The time slot allocation method described in this embodiment can be applied to traffic ap...

example 1

[0105] Such as Figure 4 As shown, the slot allocation method based on game theory provided in this example includes the following steps:

[0106] S101: Divide the vehicles at the intersection into two game groups A and B according to their geographical locations.

[0107] S102: The first game group A selects a representative vehicle V A , the second game group B chooses a representative vehicle V B , where, represents the vehicle V A and represent the vehicle V B As a participant in the bargaining game.

[0108] S103: Determine the first game participant V A and the second player V B The strategic spaces are: {S i ,W i}, where S i and the values ​​of Wi are 0 and 1, S i and W i The sum is always 1. S i When it is 1, it means that the game participants send data in the i-th time slot, W i When it is 1, it means that the game participants in the i-th time slot are in the state of waiting to send data.

[0109] S104: The first game participant V A and the second ...

Embodiment 2

[0128] Such as Figure 7 As shown, this embodiment provides a time slot allocation device, the device includes:

[0129] The grouping unit 110 is used to divide the vehicle-mounted devices that have not obtained time slots in the target area into N game groups according to the geographic location; the N is an integer not less than 2; each group includes at least one vehicle-mounted device;

[0130] A selection unit 120, configured to select one vehicle-mounted device as a game participant for each game group;

[0131] Determining unit 130, configured to determine the strategic space for each game participant to participate in the i-th time slot game;

[0132] The gaming unit 140 is configured to conduct a game for each of the game participants according to the strategic space, and solve the game result to obtain a Nash equilibrium solution;

[0133] The allocation unit 150 is configured to allocate the ith time slot to corresponding game participants according to the Nash eq...

Abstract

An embodiment of the invention discloses a time slot distribution method and apparatus. The method comprises the following steps: vehicle-mounted devices which obtain no time slot in a target zone are divided into N game groups according to geographic positions; N is an integer equal to or greater than 2, each group at least comprises one vehicle-mounted device, one vehicle-mounted device is chosen as a game participator for each game group, a strategic space of each game participator participating in an ith time lot game is determined, all game participators participate in the game according to strategic spaces, a game result is solved and a Nash equilibrium solution is obtained; according to the Nash equilibrium solution, an ith time slot is assigned to a corresponding game participator.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a time slot allocation method and device. Background technique [0002] In the vehicle ad hoc network based on cooperative communication, for a vehicle entering the coordination area, the vehicle uses the Long Term Evolution (LTE) network to report the registration information of the vehicle to the base station. The vehicle is randomly assigned a time slot, but the vehicle can only send status information within the assigned time slot. Since the time slot obtained by the vehicle is randomly assigned, it cannot be guaranteed that the emergency information of the vehicle can be sent in time. The communication efficiency of the vehicular ad hoc network is reduced, and the optimization of wireless resources cannot be realized, and the utilization efficiency of time-frequency resources is low. Contents of the invention [0003] In view of this, the embodiments of the p...
