Centrally Assisted Local Manager Selection in P2P Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In peer to peer wireless networks, the selection of local managers by user equipment (UEs) is often sub-optimal due to limited criteria such as signal strength, lack of centralized control, and dynamic updates, leading to inefficient associations.
Innovation Solution
A centrally assisted mechanism that allows UEs to select local managers based on association parameters, including network metrics and cost metrics, with the network device providing criteria and feedback to improve the selection process, enabling better resource management and connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If UEs select local managers based on limited local criteria (signal strength only), then the workload of UEs is reduced and the system is simpler, but the selection quality becomes sub-optimal
Solution Approach 1:
The patent introduces an association parameter as an intermediary element that mediates between the simple signal strength measurement and the complex selection decision. This association parameter, provided by the network device, encapsulates multiple factors (signal strength, load, priority, cost metrics) into a single guidance value that UEs can use for selection without needing to process complex multi-factor decisions themselves.
Solution Approach 2:
The patent implements feedback mechanisms where network devices provide association parameters to UEs based on network state information, and UEs report their selections and measurements back to the network. This closed-loop feedback enables the network to optimize association parameters dynamically, improving selection quality without increasing UE complexity.
2Reliability
If centralized control is introduced to improve selection quality, then selection optimization improves, but system overhead increases
Solution Approach 1:
The patent applies partial centralized control by having network devices provide association parameters only when needed for selection decisions, rather than continuous full control. The network provides guidance parameters selectively based on network conditions, achieving optimization only where necessary while minimizing overhead.
Solution Approach 2:
The patent changes the form of information exchange by using compact association parameters (such as cost metrics or priority values) instead of exchanging detailed multi-factor state information. This parameter transformation reduces overhead while preserving the essential information needed for optimized selection.
3Reliability
If dynamic updates and multiple metrics are analyzed for selection, then selection quality improves, but UE workload increases
Solution Approach 1:
The patent extracts the complex multi-metric analysis function from the UE and relocates it to the network device. The network device performs the computationally intensive task of analyzing multiple metrics (signal strength, load, priority, cost) and extracts only the essential association parameter needed by the UE for decision-making.
Solution Approach 2:
The patent implements preliminary action by having the network device pre-calculate and provide association parameters to UEs before the UEs need to make selection decisions. This preliminary processing by the network eliminates the need for UEs to perform complex real-time analysis during selection events.
