Wireless Network Timer Adjustment via Dynamic Location Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network technologies do not dynamically adjust timer values for transmission control, leading to suboptimal performance due to fixed distance parameter configurations, resulting in decreased throughput as non-root nodes often operate at distances shorter than the maximum reachable distance.
Innovation Solution
Implementing a dynamic location-based system, such as GPS, to determine the location of non-root nodes and set timer values based on the distance of the farthest node from the root node, optimizing transmission control parameters like Inter-Frame Spaces and Slot Time.

Engineering Contradiction Analysis
1Area of stationary object
If the distance parameter is configured using the maximum reachable distance to ensure all non-root nodes can access the root node, then the coverage area is improved, but the timer values become excessively large for nodes at shorter distances, decreasing network throughput
Solution Approach 1:
The patent applies local quality by configuring distance parameters individually for each non-root node based on its specific distance from the root node, rather than using a uniform maximum distance for all nodes. Each node receives a customized distance parameter that matches its actual communication range requirements, eliminating the throughput degradation caused by overly conservative timer values.
Solution Approach 2:
The patent implements dynamics by making the distance parameter configuration adaptive and node-specific. The root node dynamically determines appropriate distance parameters for each non-root node based on actual deployment conditions and distances, allowing the system to optimize performance for each local situation rather than relying on static maximum values.
2Ease of operation
If fixed distance parameter configuration is used to simplify deployment, then the ease of operation is improved, but the timer values are not optimized for actual node distances, resulting in decreased network performance
Solution Approach 1:
The patent applies self-service by enabling the root node to automatically determine and configure optimal distance parameters for each non-root node based on their actual distances. This eliminates the need for manual configuration while achieving optimized performance, as the system self-adjusts parameters based on measured or calculated distances between nodes.
3Reliability
If timer values are set based on maximum reachable distance to ensure reliable communication for all nodes, then the reliability is improved, but nodes at shorter distances experience unnecessary waiting times, increasing loss of time
Solution Approach 1:
The patent applies local quality by setting timer values specific to each node's distance from the root node. Nodes at shorter distances receive smaller timer values appropriate to their communication conditions, while nodes at maximum distance receive larger values to ensure reliability. This localized timing configuration maintains reliability for all nodes while eliminating unnecessary waiting time for closer nodes.

AI summary
A root node sets wireless network timer values by using dynamic location information of a plurality of non-root nodes. In an embodiment, the root node and the non-root nodes are bridges, wherein the non-root bridges are connected to the root bridge in a point-to-point or point-to-multipoint manner. The locations of the nodes are determined by using a location system and locations receivers. The root node and each of the non-root nodes use this location information to determine the optimum timer values for the wireless network, thereby improving throughput on the wireless network. In one embodiment, the location system is the global positioning system (GPS). The location receiver is a GPS location receiver that is embedded in each of the nodes. In another embodiment, the GPS location receiver is external to the nodes, and the location information is determined remotely.
