A self-healing method for joint access point selection and resource allocation in ultra-dense networks

Abstract

The present invention is a self-healing method for joint access point selection and resource allocation under an ultra-dense network, which belongs to the field of ultra-dense networks; specifically: firstly, the WNCU judges whether there is an access point failure, and if so, the WNCU records the The list of communication-impaired users being served by the access point is broadcast to adjacent access points; each adjacent access point dynamically divides the self-healing sub-channel from the normal sub-channel; then, the communication-impaired users are divided according to the self-healing channel As a result and its own rate request, it selects an appropriate neighboring access point to continue obtaining services. Finally, the access point uses the quantum particle swarm algorithm to re-allocate resources for the original users and the newly accessed communication-impaired users; the advantage is that it realizes the self-healing function under the ultra-dense network. It effectively guarantees the service requirements of communication-impaired users, improves system energy efficiency, and reduces operating costs.

Description

technical field [0001] The invention belongs to the field of ultra-dense networks, in particular to a self-healing method for joint access point selection and resource allocation in an ultra-dense network. Background technique [0002] In an ultra-dense network, dense network deployment makes the network topology more complex. In order to improve network management efficiency and reduce operating costs, self-organizing technology is introduced into the ultra-dense network to achieve intelligent and flexible network management. [0003] One of the three major functions of self-organizing technology is self-healing technology, which can alleviate or eliminate the adverse effects of network failures by taking certain restoration and compensation operations. Self-healing technology generally includes three parts, fault detection, analysis and recovery. Existing self-healing mechanisms mainly focus on fault detection and analysis, but less research on fault recovery. [0004] I...
