Problems solved by technology

However, existing schemes do not take this into account
In addition, there are still the following problems in the existing incentive scheme based on the transfer of licensed frequency band usage rights: (1) The selection of the relay station is either a centralized method in which the base station is responsible, or a distributed mode in which the terminal nodes are coordinated, which cannot make full use of both. The advantages of the former, and no specific solution is given on how to achieve
(2) The requirements for relay stations are too high
Requiring the base station to accurately track the channel state information (ChannelState Information, CSI) of all users on all frequency bands will also increase the workload of the base station enormously

Embodiment Construction

[0129] The overall scheme proposed by the present invention consists of the following six algorithms.

[0130] Algorithm 1: Construct a preliminary relay path.

[0131] The algorithm runs on the base station.

[0132] Input parameter: the information set of the candidate relay node (such as R k ) and source node information (such as s k ). Among them, R k is a set, which saves the information of all candidate relay nodes covered by the kth receiving sector of the receiving antenna of the base station; s k is a variable that stores the information of a source node covered by the kth receiving sector of the receiving antenna of the base station.

[0133] Output: Preliminary trunk path

[0134] 1. Use the formula Calculate the distance L between the source node and the base station s,d . Among them, (x s ,y s ) and (x d ,y d ) represent the coordinates of the source node and the base station, respectively.

[0135] 2. Use the formula Calculate the intersection di...

Abstract

The invention discloses a method for communication strategy selection and resource allocation of a wireless terminal based on a Stackelberg game. A three-party collaborative resource allocation plan is designed based on a Stackelberg game model. According to the method, a base station can determine preliminary division of a spectrum band authorized by the base station for a requester and power distribution shares of all relays participating in communication and collaboration, and the requester and the relays can respectively dynamically adjust an initial allocation bandwidth value and a transmission power value during data transmission according to the feedback information, so that the utilization rate of wireless resources can be further improved, the relay communication performance under the condition that a source node is far from a target node can be remarkably improved, the overall energy consumption of a network is reduced, the system access capacity is improved, and the method is beneficial to optimizing the wireless resource allocation and promoting the overall performance of the network.

Description

technical field [0001] The invention belongs to computer network application and wireless network resource management technology, in particular to a wireless terminal communication strategy selection and resource allocation method based on Stackelberg game in a wireless cellular network environment. Background technique [0002] With the emergence of a large number of wireless multimedia applications, the traffic of wireless terminals is also increasing rapidly. For example, notification information of social networks, traffic information release of intelligent transportation network, update of electronic map information, news push and other content update and distribution applications, as well as uploading of large-capacity video files such as instant shooting and transmission, require wireless terminals to process and transmit Massive Data. [0003] With the help of multi-hop relay, the traditional cellular network can improve the communication quality of the coverage are...
