Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern wireless communication devices face interference and inefficiencies when managing concurrent wireless communication over multiple mediums, leading to packet loss and increased power consumption due to incorrect bandwidth assumptions, especially when Internet protocol packets are transmitted over WLAN without awareness of scheduling limitations.
Innovation Solution
A multiradio controller manages wireless communication by receiving information from active mediums, formulating operational schedules, and adjusting the maximum transfer unit (MTU) for Internet Protocol packets to align with the operational schedule of the supporting wireless communication medium, ensuring packet sizes match available bandwidth and minimizing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If Internet protocol packets are transmitted over WLAN without awareness of scheduling limitations, then communication bandwidth is maximized, but packet loss increases due to interference from concurrent wireless mediums
Solution Approach 1:
The system implements feedback by monitoring the operational schedules of multiple wireless communication mediums and using this information to dynamically adjust IP packet transmission parameters. The multiradio controller provides feedback about scheduled transmission times and potential interference, allowing the IP stack to adapt its packet size and timing accordingly, thus preventing packet loss while maintaining efficient bandwidth utilization.
Solution Approach 2:
The invention applies preliminary action by determining the operational schedules of concurrent wireless mediums before transmitting IP packets. The system proactively identifies time periods when interference may occur and adjusts packet transmission parameters in advance, rather than reacting to packet loss after it occurs. This preemptive approach ensures packets are transmitted during optimal time windows with minimal interference risk.
2Reliability
If packet retransmission occurs due to packet loss, then communication reliability is improved, but power consumption increases significantly
Solution Approach 1:
The system applies preliminary anti-action by preventing packet loss before it occurs through schedule-aware packet size adjustment. By analyzing operational schedules and adjusting IP packet parameters proactively, the invention eliminates the need for retransmission, thereby avoiding the additional power consumption that would result from repeated transmission attempts. This preventive strategy maintains communication reliability while minimizing energy expenditure.
3Adaptability or versatility
If multiple wireless communication mediums operate concurrently, then device functionality is enhanced, but interference between mediums increases leading to communication inefficiency
Solution Approach 1:
The invention implements dynamics by making IP packet transmission parameters adaptive rather than static. The system dynamically adjusts packet size, transmission timing, and other parameters based on the real-time operational schedules of multiple wireless mediums. This dynamic adaptation allows concurrent mediums to operate with minimal interference, maintaining both enhanced device functionality and efficient communication across all active wireless interfaces.
