Wireless Network Message Exchange for Beacon Position Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless personal area networks (WPANs), insufficient channel resources can lead to communication failures when a large number of devices attempt to transmit data, especially with high-capacity data like moving pictures, due to inadequate allocation of channel resources, and the management and control by a coordinator can be affected by the status of individual devices, impacting communication quality.
Innovation Solution
A method for exchanging messages between devices and a coordinator in a wireless network that allows a device to request changes in WPAN configuration parameters, such as beacon position and superframe duration, enabling the coordinator to adjust these parameters to optimize data communication efficiency, thereby minimizing buffering and improving data output procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the coordinator manages and controls the WVAN, then the network can be organized and timed, but communication quality deteriorates when individual device statuses affect coordination
Solution Approach 1:
The patent segments the coordinator's control functions by introducing separate request message and response message channels. Devices can independently request parameter changes and receive coordinated responses, dividing the monolithic coordinator control into modular interaction steps that reduce bottlenecks and improve reliability.
Solution Approach 2:
The patent implements dynamic parameter adjustment where the coordinator can modify WVAN configuration parameters (beacon position, superframe duration) based on real-time device status and network conditions. This dynamic adaptation allows the system to maintain stability while responding to changing individual device states, preventing communication quality deterioration.
2Quantity of substance
If channel resources are allocated to accommodate many devices, then device connectivity increases, but data transmission speed decreases due to resource sharing
Solution Approach 1:
The patent enables dynamic adjustment of superframe duration and beacon position based on network load and device requirements. When high-capacity data transmission is detected, the coordinator can extend superframe duration to provide more channel resources, thereby maintaining transmission speed even as the number of connected devices increases.
Solution Approach 2:
The patent changes key timing parameters (beacon position offset, superframe duration) to optimize resource allocation. By adjusting these parameters dynamically, the system can allocate more channel capacity to devices transmitting high-capacity data while maintaining connectivity for multiple devices, resolving the trade-off between quantity and speed.
3Stability of the object's composition
If beacon position is fixed, then network timing is stable, but buffering increases when device data output timing does not align with network timing
Solution Approach 1:
The patent makes the beacon position dynamic by allowing devices to request offsets from their expected beacon positions. The coordinator evaluates these requests and adjusts beacon timing to align with device data output intervals, reducing buffering requirements while maintaining overall network timing stability through controlled, incremental adjustments.
Solution Approach 2:
The patent implements a feedback mechanism where devices monitor their buffering status and send request messages to the coordinator when misalignment is detected. The coordinator responds with adjusted beacon positions based on this feedback, creating a closed-loop control system that minimizes buffering while preserving timing stability.

AI summary
A method of exchanging messages at a device in a wireless network comprises transmitting a change request message for requesting a change of a beacon position among configuration parameters of the wireless network to a coordinator; and receiving a response message in response to the request message from the coordinator.
