Low-energy-consumption network design method based on node dependency and ONU modular dormancy

Abstract

The invention relates to a low-energy-consumption network design method based on node dependency and ONU modular dormancy, and belongs to the technical field of optical wireless hybrid network communication. The method aims at the problem that the existing energy saving mechanism based on node dormancy cannot effectively reduce network energy consumption, through judging the size of current working load of the ONU and the size of the dependency between the dormant ONU and the wireless router, allows the node to enter the dormant state by performing load transfer based on a front-end mesh, and further reduce the energy consumption of the whole network through combining with the modular dormancy technology in the DBA algorithm. According to the method, on the basis of being capable of effectively reducing the energy consumption of the whole network, the access requirement of the user and the connection requirement of the network are met, and meanwhile obvious significance is not generated for time delay of the network data package.

Description

technical field [0001] The invention belongs to the technical field of optical wireless hybrid network communication, and relates to a low energy consumption network design method based on node correlation and ONU modular dormancy. Background technique [0002] With the increasing popularity of smart phones, home computers and other terminals, the data volume of wireless and wired communication services is increasing exponentially, and the traditional access methods are increasingly unable to meet the growing bandwidth requirements of users. The access network begins to evolve toward high bandwidth and high mobility. Optical and wireless fusion access network (Wireless Optical Broadband Networks, WOBAN) is a new network structure composed of a back-end passive optical network (Passive Optical Network, PON) and a front-end wireless network. Due to its point-to-multipoint topology, the optical access network greatly reduces the number of optical interfaces on the network side...

AI Technical Summary

Problems solved by technology

However, the above mechanism does not comprehensively consider the dormancy of the ONU and the wireless router in combination with the optical side and the wireless side of WOBAN, because the dormancy of the front-end wireless router will affect the connectivity of services in the network and the access coverage of users.

In addition, in the WOBAN with multiple hops, the above documents do not consider the modular sleep of the ONU, which will inevitably lead to a decrease in energy saving efficiency
