Wireless Mesh Time Slot Allocation by Node Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless mesh networks face inefficiencies in time slot allocation during network commissioning, leading to unsatisfactory speed and insufficient utilization of network geometry, as previous methods do not effectively account for node distances and communication paths.
Innovation Solution
Time slots are allocated based on distance to the master node, with direct slave nodes receiving lowest ordinal numbers and nodes further away receiving higher numbers, ensuring that communication relations are processed in an optimized sequence, allowing transmitter and receiver roles to be swapped within corresponding time slots, using the formula Ordnungszahl korrespondierender Zeitschlitz = Anzahl der Zeitschlitze pro Zeitschlitzperiode + 1 − Ordnungszahl Zeitschlitz to match pairs and facilitate fast communication in both directions.

1Extent of automation
If time slots are allocated during self-controlled commissioning without considering node distance, then network commissioning can proceed autonomously, but transmission speed becomes unsatisfactory and network geometry is insufficiently utilized
Solution Approach 1:
The patent changes the parameter of time slot allocation from random/sequential to distance-based hierarchical allocation. Nodes are assigned time slots according to their distance from the master node, creating a structured allocation pattern that optimizes transmission speed while preserving autonomous commissioning capability.
Solution Approach 2:
The patent introduces a spatial dimension (distance from master node) into the time slot allocation process. By mapping physical network geometry onto the time domain through distance-based assignment, the system utilizes network geometry to improve transmission efficiency without compromising automation.
2Ease of manufacture
If time slots are allocated without considering network geometry, then allocation process is simple, but network geometry is insufficiently utilized leading to suboptimal communication efficiency
Solution Approach 1:
The patent transforms the allocation parameter from simple sequential numbering to distance-based hierarchical numbering. This change incorporates network geometry into the allocation process, improving communication efficiency while maintaining relative simplicity through automated distance measurement and assignment.

AI summary
The invention relates to a method for transmitting data packets in a wireless interconnected network having a plurality of nodes, wherein a fixed time slot having an ordinal number is assigned to each communication relation between the nodes and the communication relations are performed in the order of said ordinal numbers. A corresponding time slot in which transmitter and receiver are exchanged is assigned to each time slot. The corresponding time slot is assigned in accordance with the stipulation that the next higher ordinal number for the corresponding time slot is assigned to the next lower ordinal number for a time slot.
