Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face collisions when multiple devices attempt to transmit requests simultaneously after receiving paging messages, leading to corrupted data and reduced efficiency in data delivery.
Innovation Solution
The implementation of a method where wireless devices receive paging messages with an ordering and multiplier, determining a wake-up time based on these parameters to minimize collisions by controlling when devices wake up and transmit requests, allowing for efficient data reception and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple devices wake up simultaneously to transmit requests after receiving paging messages, then devices can efficiently receive data, but collisions occur leading to corrupted data and reduced efficiency
Solution Approach 1:
The patent segments the simultaneous wake-up event into multiple time-divided wake-up instances. Devices calculate different wake-up times based on their device ID and a multiplier parameter, spreading out the wake-up and request transmission events across different time slots. This temporal segmentation eliminates collisions while maintaining efficient data delivery.
Solution Approach 2:
The patent introduces dynamic wake-up time calculation where each device determines its wake-up time based on a formula involving its device ID and a multiplier. This dynamic approach ensures that devices with different IDs naturally wake up at different times, adapting the wake-up schedule to the specific device configuration while preventing simultaneous transmissions.
2Use of energy by moving object
If devices wake up at the same time to transmit requests, then power consumption is optimized by staying in doze state, but collisions occur causing data corruption
Solution Approach 1:
The patent implements preliminary action by having devices calculate their wake-up times in advance based on the paging message parameters (device ID and multiplier) before actually waking up. This pre-calculation allows devices to stay in the low-power doze state until their specific wake-up time, optimizing power consumption while ensuring they wake up at collision-free moments for reliable transmission.
3Speed
If devices transmit requests simultaneously after paging, then data delivery speed is improved, but collisions reduce overall network efficiency
Solution Approach 1:
The patent implements periodic action through time-divided wake-up intervals. Instead of simultaneous transmission, devices transmit requests at periodically spaced intervals determined by their calculated wake-up times. This periodic distribution maintains steady data delivery speed while eliminating collisions that would reduce network efficiency.
