Wireless Network Instant Channel Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network methods for allocating channel resources are inadequate for instant data transmission, leading to delays and uncertainty in message exchange between devices, particularly when timing constraints are involved, and can result in data collisions during contention-based message exchange.
Innovation Solution
A method for allocating instant channel resources in a wireless network involves receiving channel resource allocation information from a coordinator, requesting and announcing instant channel resource allocation within an unreserved duration of a superframe, ensuring timely and collision-free message transmission by utilizing specific channel resources for both message transmission and response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If channel resources are allocated through coordinator-based request and beacon transmission, then resource allocation is centralized and controlled, but message transmission delay increases and timing constraints cannot be met
Solution Approach 1:
The patent divides the superframe into reserved and unreserved durations, pre-establishing the unreserved duration as a contention-based access period where devices can immediately transmit messages without waiting for coordinator allocation. This preliminary structuring of time resources allows instant access while maintaining overall centralized control through the reserved duration.
Solution Approach 2:
The superframe is segmented into two distinct functional periods: reserved duration for coordinated resource allocation and unreserved duration for immediate contention-based access. This segmentation allows the system to simultaneously support both centralized control and rapid instant message transmission by directing different types of traffic to appropriate segments.
2Speed
If contention-based message exchange is used in unreserved region, then instant message transmission is enabled, but data collision occurs between devices
Solution Approach 1:
The patent dynamically adjusts the length and number of unreserved regions based on network conditions and traffic requirements, allowing the contention-based access period to be optimized for both speed and reliability. The coordinator can modify these parameters to balance immediate access needs against collision probability.
Solution Approach 2:
The coordinator acts as an intermediary that manages the unreserved duration by controlling its parameters and monitoring collision patterns. When collisions occur, the coordinator can adjust the unreserved region configuration or redirect traffic to the reserved region, mediating between the need for fast access and the need to prevent collisions.

AI summary
A method of allocating channel resources in a wireless network is disclosed. The method of allocating instant channel resources in a wireless network includes receiving channel resource scheduling information of a specific superframe from a coordinator of the wireless network, requesting the coordinator to allocate instant channel resources for an unreserved duration of the specific superframe, and receiving an announcement message from the coordinator, the announcement message announcing allocation of the instant channel resources within the unreserved duration of the specific superframe.
