Problems solved by technology

Most of the existing wireless router layout methods are aimed at wireless Mesh networks, and are limited to peer-to-peer communication between router nodes, and are not perfect in terms of wireless access hops and network coverage.
Therefore, it cannot be effectively applied to the deployment of passive optical network based on ONU-WG

Embodiment Construction

[0047] like figure 2 Shown, the present invention is based on the passive optical network optimization method of ONU-WG, and the present invention comprises the following steps:

[0048] Step 1: Divide the entire network area into M×M grid units, and use the center of each grid unit as a possible location for placing a wireless router.

[0049] Step 2: Let R k Indicates a wireless router to be placed at present. Under the condition of meeting the ONU capacity limit and the wireless access hop limit, it is calculated that the wireless router R can be placed k all candidate positions. At each candidate position, R k The destination ONU can be accessed through at least one wireless path that satisfies the hop constraint, and the destination ONU has enough remaining capacity to carry R k business volume.

[0050] Step 3: Follow the wireless router R k The transmission range of , calculate its achievable network coverage at each candidate location, where the network coverage...

Abstract

The invention belongs to the technical field of communication network, in particular relates to a passive optical network optimization method based on ONU-WG. The passive optical network optimization method based on ONU-WG adopts an ONU-WG structure for optical fiber unreachable region, not only can support broadband access of wireless terminal equipment anytime and anywhere, and provides feasibility for applications based on passive optical network such as emergency communication and remote monitoring. The ONU-WG is served as an interface, a wireless multi-hop network is established at the front end of a passive optical network, the network coverage area can be extended, the optical fiber laying distance can be shortened, and the network deployment cost can be saved. The network expansibility is good, the original architecture of the passive optical network can be kept, only parts of ONU need to be replaced by the ONU-WG, the installation is easy, the cost is low and the maintenance is convenient. The passive optical network optimization method aims at maximizing the network coverage area, and reduces the network subsequent construction cost. The passive optical network optimization method obtains an optimal layout scheme for a wireless router by adopting an efficient heuristic method, and is more suitable for large-scale network deployment.

Description

technical field [0001] The invention belongs to the technical field of communication networks, in particular to an ONU-WG-based passive optical network optimization method. Background technique [0002] In recent years, the increasing number of multimedia service users has led to an exponential growth trend in Internet traffic. According to reports, in the next ten years, the annual growth rate of Internet business volume will exceed 75%, and the annual growth rate of video services with higher bandwidth requirements will reach 45%. This indicates that the traditional access technology with limited rate, such as 20-30Mbps digital subscriber line technology DSL, can no longer meet the ever-increasing bandwidth demand, and the access network covering the "last mile" will gradually become the link between user terminals and the Internet. The design of broadband access network in the future will face greater challenges. [0003] Passive Optical Network (Passive Optical Network...
