Cross-domain cooperative resource allocation method for optical fiber wireless convergence network

Abstract

The invention discloses a cross-domain cooperative resource allocation method for an optical fiber wireless convergence network. The method comprises the following steps of: dividing the network intoa plurality of branch network regions according to a proximity principle and a whole network approximate average principle; through a load-transferred ONU and wireless node cooperative region resourceredistribution mechanism, redistributing routes for influenced service requests of a dormant region according to service priorities, and selecting a maximum weight path as a current forwarding path of the service request and a source node MAP thereof based on constraint factors; an energy consumption model of a whole network is established through calculation of on-off energy consumption EONU ofONU equipment of an optical network unit, on-off energy consumption EMAP of MAP equipment of a wireless node and forwarding energy consumption Etrans of a service request, and then network service maximization earnings are obtained in combination with a network service earning model. According to the technical scheme provided by the invention, the ONU subjected to load transfer and the wireless node cooperatively sleep, and the route is redistributed according to the priority; and the service quality of the high-priority service is ensured on the basis of maximally reducing the network energyconsumption.

Description

technical field [0001] The present invention relates to the field of resource allocation of an optical fiber and wireless converged network, in particular to a cross-domain collaborative resource allocation method for an optical fiber and wireless converged network. Background technique [0002] The power distribution communication network is an important connection between the backbone transmission network in the power communication network and the user's local network, and it carries services such as power dispatching, intelligent meter reading, and distribution network protection. As the scale of the power grid continues to expand, the number and types of services carried on the distribution and consumption communication network are increasing. As a result, the traditional single network structure cannot meet the end-to-end and differentiated transmission quality requirements of heterogeneous services. Optical fiber wireless broadband access network not only has the advan...
