Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks lack efficient mechanisms to control network resource usage as network topology changes, leading to excessive power consumption and battery drain in mobile devices due to continuous resource usage when moving out of coverage areas.
Innovation Solution
A location-based resource-management system that uses a GPS receiver to determine the position of network devices and adjust resource usage based on predetermined network information, such as turning off transceivers when outside a coverage area, thereby optimizing power consumption and resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless devices continuously use network resources to maintain connectivity, then network coverage and service availability are improved, but power consumption increases and battery life decreases
Solution Approach 1:
The patent implements dynamic resource adjustment by continuously monitoring GPS location data and automatically transitioning network resources between active and inactive states based on coverage area detection. This dynamic adaptation allows the system to optimize power consumption while maintaining connectivity only when needed, resolving the contradiction between continuous service availability and energy efficiency
Solution Approach 2:
The system employs feedback mechanisms by monitoring device location relative to known coverage areas and using this information to control network resource states. The continuous location tracking and conditional resource activation create a closed-loop control system that adjusts power consumption based on actual connectivity needs, thereby improving battery life while preserving network reliability
2Adaptability or versatility
If wireless devices continuously monitor network topology changes, then network adaptability is improved, but processing overhead and energy consumption increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring coverage area boundaries and network resource states before actual topology changes occur. The system pre-establishes the conditions for resource activation/deactivation based on geographic locations, allowing rapid adaptation to topology changes without continuous monitoring overhead, thus reducing energy consumption while maintaining high adaptability
Solution Approach 2:
The system implements partial monitoring by selectively tracking only the GPS location data necessary for coverage area determination, rather than continuously monitoring all network topology parameters. This partial action approach provides sufficient adaptability for location-based resource management while significantly reducing processing overhead and energy consumption compared to comprehensive topology monitoring
