Dynamic Wireless Network Resource Allocation via Join-Leave Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems are limited in the number of devices that can join a network due to occupied bandwidth, and require periodic clock updating for synchronization, leading to increased power consumption and costs.
Innovation Solution
Implement a system where wireless devices request to join the network at estimated times, are allowed to leave after completing communication, and manage their state to release resources, reducing the need for continuous synchronization and power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wireless devices maintain continuous network connection and periodic clock updating, then time synchronization is maintained, but power consumption increases and device cost increases
Solution Approach 1:
The patent implements periodic clock updating only when necessary - devices update their clocks periodically when they join the network or when synchronization is needed, rather than maintaining continuous synchronization. This allows devices to enter low-power states between updates, reducing overall power consumption while maintaining time synchronization accuracy when active.
Solution Approach 2:
The patent extracts the clock updating function from continuous operation and performs it only at specific moments (when joining network or when synchronization is required). This separates the synchronization function from continuous network presence, allowing devices to reduce power consumption by not maintaining constant network connections.
2Speed
If wireless devices occupy network resources continuously, then real-time communication is enabled, but the number of devices that can join the network is limited
Solution Approach 1:
The patent makes network resource allocation dynamic rather than static. Devices can join and leave the network based on communication needs, with the system manager dynamically allocating time slots and frequencies. This allows the network to support more devices by allocating resources only when and where needed, rather than reserving resources for all potential devices continuously.
Solution Approach 2:
The patent implements a mechanism where network resources are discarded (released) when not in use and recovered (reallocated) when needed. Devices that have completed communication leave the network, freeing up their allocated time slots and frequencies for other devices. This resource recycling enables the network to support a larger number of devices over time.
3Quantity of substance
If wireless devices join and leave the network dynamically, then more devices can be supported, but network management complexity increases
Solution Approach 1:
The patent introduces a system manager as an intermediary that handles the complexity of dynamic network management. The system manager receives join/leave requests, allocates time slots and frequencies, and coordinates clock updates. This centralizes the management complexity in a dedicated component rather than requiring each device to independently manage network resources, making the overall system more manageable despite supporting dynamic device participation.

AI summary
A wireless communication system includes a wireless device configured to make a request to join a wireless network in a case that a first estimated joining time is reached, the first estimated joining time being a time to join the wireless network. In addition, the wireless communication system includes a management device configured to cause the wireless device that made a joining request to join the wireless network, and cause the wireless device to leave the wireless network, the leave of the wireless device being caused in a case that a wireless communication by the wireless device via the wireless network is completed.
