Problems solved by technology

Most of the existing wireless router layout methods are aimed at wireless mesh networks, and the survivability of wireless optical broadband access networks is less considered, and the considerations of wireless access hops and network coverage are not perfect.
Therefore, it cannot be effectively applied to the optimal deployment of wireless optical broadband access network based on survivability rerouting

Embodiment Construction

[0057] As shown in the figure, the present invention comprises the following steps:

[0058] 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.

[0059] Step 2: Let R x Indicates a wireless router to be placed currently. Under the condition that there are k node disjoint paths from each ONU to another ONU and the constraints of wireless access hops, it is calculated that the wireless router R can be placed x All candidate positions of all ONUs, thereby determining the backup ONUs of all ONUs. Place the wireless router R on the candidate location x , to ensure that any ONU can access another ONU through k wireless paths that satisfy the hop constraint and are node-disjoint.

[0060] Step 3: Follow the wireless router R x The transmission range, calculate the network coverage after placing these wireless routers. The network coverage here is calculated based on whether the us...

Abstract

The invention especially relates to a wireless optical broadband access network optimization deployment method based on survivability rerouting, and belongs to the technical field of communication networks. The wireless optical broadband access network optimization deployment method SRRD based on survivability rerouting is used for achieving the purpose of the optimized layout of wireless routers. The method includes the following steps that firstly, a whole network region is divided into M*M grid cells, and the center of each grid cell serves as a possible position for containing one wireless router; secondly, Rx is set for representing the wireless routers currently to be placed, under the conditions that k node-disjoint paths and wireless access hop count constraints exist from each ONU to another ONU, all the candidate positions capable of containing the wireless routers Rx are calculated.

Description
