Shared Spare Time Mechanism for Wireless Bandwidth Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless networking architectures waste bandwidth due to each device reserving unused spare time for potential retransmissions, leading to congestion and limited connectivity as the number of devices increases, especially in environments with multiple wireless devices competing for bandwidth.
Innovation Solution
Implementing a shared spare time mechanism within a wireless network architecture where devices can retransmit data during designated shared spare times, allowing the arbiter device to prioritize and schedule activities based on data stream priority, reducing wasted bandwidth and increasing available communication slots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each device reserves spare time for potential retransmissions, then reliability of data transmission is improved, but bandwidth is wasted and congestion increases
Solution Approach 1:
Multiple individual spare time slots are merged into a single shared spare time slot that can be used by any device in the network. This consolidation allows the system to maintain reliability through retransmission capability while eliminating the bandwidth waste associated with each device reserving its own dedicated spare time.
Solution Approach 2:
The shared spare time slot serves multiple functions: it can be used by any device for retransmissions, and when no retransmissions are needed, the time can be utilized for other network activities. This multi-functionality resolves the contradiction by making the spare time resource universally useful rather than dedicated to single devices.
2Reliability
If each device reserves dedicated spare time, then retransmission capability is ensured, but the number of connected devices is limited
Solution Approach 1:
By combining multiple dedicated spare time slots into one shared spare time slot, the system can support more devices simultaneously. The shared slot is accessed by any device needing retransmission, allowing the network to accommodate a larger number of connected devices without requiring each to have its own dedicated spare time.
Solution Approach 2:
The shared spare time mechanism dynamically assigns access rights based on actual transmission needs rather than static dedicated allocations. This dynamic approach allows the system to adapt to varying numbers of active devices and maintain reliability only when needed, thereby supporting more connected devices overall.
3Ease of operation
If dedicated spare time is allocated to each device, then data retransmission is facilitated, but communication bandwidth is reduced
Solution Approach 1:
Multiple dedicated spare time allocations are merged into a single shared spare time slot, which maintains the ease of performing retransmissions while significantly increasing the available communication bandwidth. The shared slot is accessed only when necessary, leaving more bandwidth available for primary data transmissions.
Solution Approach 2:
Instead of allocating full dedicated spare time to each device, the system provides partial access to a shared spare time slot only when retransmission is actually needed. This partial action approach maintains retransmission capability while maximizing overall communication bandwidth utilization.

AI summary
In some embodiments, a system can include a first client device connected to an arbiter device, a second client device connected to the arbiter device; and a wireless network architecture that provides a shared spare time during which one selected client device of the first client device or the second client device retransmits a portion of a previously transmitted message to the arbiter device.
