Centralized Network Resource Reservation via Slave Link Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In centralized networks, resource allocation between a master device and slave devices is inefficient due to inaccurate checking of communication link states, leading to suboptimal resource allocation.
Innovation Solution
A resource reservation method that includes link measurement and negotiation between devices, where the master device and slave devices exchange resource reservation requests and responses, and include reservation information in beacons to ensure accurate allocation of resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the master device allocates resources by checking situations of other slave devices through communication channels with the master device, then resource allocation can be performed, but the state of communication link between slave devices cannot be accurately checked leading to inefficient resource allocation
Solution Approach 1:
The patent introduces slave devices as intermediaries that directly measure and report communication link states between themselves and the master device. Instead of the master device indirectly checking link states through its own communication channels, slave devices act as measurement intermediaries that provide direct feedback on actual link conditions, enabling accurate resource allocation decisions.
Solution Approach 2:
The patent implements a feedback mechanism where slave devices measure communication link states and report this information back to the master device. This feedback loop enables the master device to make informed resource allocation decisions based on actual link conditions rather than assumptions, resolving the contradiction between measurement accuracy and allocation efficiency.
2Reliability
If the master device listens to beacon periods to check resource reservation status, then resource allocation decisions can be made, but this process consumes time and reduces allocation speed
Solution Approach 1:
The patent applies preliminary action by having slave devices perform resource reservation checks and link measurements in advance before the master device needs to make allocation decisions. Slave devices proactively scan resources, perform link measurements, and prepare reservation information, so when the master device needs to allocate resources, the information is already available, eliminating the need for time-consuming beacon listening.
3Measurement precision
If slave devices perform link measurement and resource scanning, then accurate resource reservation can be achieved, but this increases device complexity and operation overhead
Solution Approach 1:
The patent implements self-service by enabling slave devices to autonomously perform link measurements, resource scanning, and reservation checks without requiring complex master device intervention. Each slave device independently measures its own communication links with the master device and other slave devices, and autonomously determines resource availability, reducing the operational complexity burden on the system.

AI summary
A resource reservation method between a master device and a slave device or between slave devices in a centralized network. In resource reservation between slave devices, optimal resources may be allocated by performing link measurement between the slave devices before allocating the resources.
