CSMA Time Slot Allocation via Beacon Frame Attributes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CSMA time slot providing methods cannot designate a specific applicable site for the CSMA time slot, leading to inefficiencies in network management and control, especially when multiple level-3 sites request access, as all sites share the same time slot without priority designation.
Innovation Solution
The method involves generating a beacon frame that carries CSMA time slots and attribute information to identify the applicable device, allowing only designated devices to use the CSMA time slot by parsing and determining the attribute information, thereby implementing flexible and controlled allocation of the CSMA time slot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all level-3 sites share the same CSMA time slot, then the network can accommodate multiple sites requesting access, but it becomes impossible to designate specific applicable sites and manage access priority
Solution Approach 1:
The patent segments the single shared CSMA time slot into multiple dedicated time slots, each assigned to specific level-3 sites based on their messaging requirements. This segmentation allows the concentrator to manage access priorities effectively while maintaining network flexibility, resolving the contradiction between accommodating multiple sites and enabling specific site designation.
2Ease of operation
If a CSMA time slot is provided without designated applicable sites, then all sites can potentially access the network, but the concentrator cannot control which sites access during different periods
Solution Approach 1:
The concentrator performs preliminary actions by pre-designating applicable level-3 sites for each CSMA time slot based on their messaging requirements before the access period begins. This preliminary designation enables automated access control while maintaining ease of operation, as sites can autonomously determine their access rights based on the pre-configured time slot assignments.
3Productivity
If multiple level-3 sites compete for the same CSMA time slot, then access requests can be handled, but conflicts occur and networking efficiency decreases
Solution Approach 1:
The patent applies local quality by assigning different CSMA time slots to different level-3 sites based on their specific messaging requirements and access priorities. This localized assignment eliminates conflicts between sites while maintaining high network throughput, as each site has dedicated access rights during its assigned time slot without interfering with other sites.
