However, the main purpose of this pricing strategy is to maximize the interests of service providers. It does not consider the end user's affordability and service requirements, and also ignores the characteristics of the RUN network, such as the role change of ordinary users or relays.

Embodiment Construction

[0025] In order to make the technical solutions and advantages of the present invention clearer, the exemplary embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all implementations. Exhaustive list of examples.

[0026] In order to achieve resource allocation and maximize the benefits of the entire network, the present invention proposes a method for centralized bandwidth allocation in a wireless LAN with relatively fixed users. The designed scenario is a cooperative scenario, that is, all users will be other users Serve.

[0027] The embodiment of the present invention provides a bandwidth allocation method in a multi-user single-relay communication system, and the main technical solutions are as follows:

[0028] like figure 1 As shown, each user’s identity is determined through the perception and re...

Abstract

The present invention provides a bandwidth allocation method in a multi-user single-relay communication system. When there are multiple users in an area, some of them can be directly connected to APs to become relays, and some of them need to connect to relay users to obtain data services. When a user enters the public LAN area, the user revenue function is discretized according to the user revenue function and the relay consumption function, and the bandwidth allocation algorithm is used to select the optimal bandwidth allocation strategy for bandwidth allocation, and the maximum service bandwidth of the relay is also considered And the user's minimum demand bandwidth limit, remove the user with low benefit to the network under appropriate circumstances, insert new user with higher benefit, and update the bandwidth allocation of the entire cluster. When the user leaves, the bandwidth is released and the bandwidth allocation is updated.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a bandwidth allocation method in a multi-user single-relay communication system. Background technique [0002] With the development of wireless local area network (WLAN), mobile users can access the Internet to obtain information, browse webpages and read emails anytime and anywhere by connecting to the access point AP. However, some users cannot access the Internet due to reasons such as limited AP connection range and poor signal strength. At this time, multi-hop access can solve this problem very well, that is, users within the signal coverage of the AP directly access the AP to become a relay, and those users who cannot directly connect to the AP can connect to the surrounding Relay to obtain Internet service indirectly. [0003] The cooperation modes of each node in WLAN are generally divided into two types: cooperative type and selfish type. In a cooperative scenari...
