Neighbor Aware Network Synchronization via Dynamic Beacon Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless devices in neighbor aware networks face challenges in reducing power consumption while maintaining effective synchronization and service discovery, as they often need to repeatedly wake up to transmit and receive synchronization and discovery messages, leading to unnecessary network overhead and potential synchronization errors.
Innovation Solution
The method involves generating and transmitting messages indicating beacon transmit window, discovery query window, and discovery query response window information, allowing devices to dynamically configure these intervals based on network parameters, enabling them to stay in a sleep state during non-transmit periods and optimize message timing to reduce power consumption and network latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless devices repeatedly wake up to transmit and receive synchronization and discovery messages, then synchronization and service discovery are maintained, but power consumption increases
Solution Approach 1:
The patent implements periodic beacon transmit windows and discovery query windows at predetermined intervals, allowing devices to remain in sleep mode between windows while maintaining network synchronization and service discovery capabilities through structured periodic communication cycles
Solution Approach 2:
The patent dynamically configures beacon transmit window intervals and discovery query window intervals based on network conditions and device states, allowing flexible adjustment of wake-up frequencies to balance power consumption with synchronization and discovery requirements
2Ease of operation
If beacon transmit windows and discovery query windows are configured with fixed intervals, then network coordination is simplified, but power consumption increases due to unnecessary wake-ups
Solution Approach 1:
The patent enables dynamic configuration of beacon transmit window intervals and discovery query window intervals, allowing the system to adapt wake-up schedules based on actual network activity and device requirements, thereby reducing unnecessary wake-ups while maintaining coordination
Solution Approach 2:
The patent changes the time interval parameters of beacon transmit windows and discovery query windows based on network conditions, allowing flexible adjustment of communication frequencies to optimize power consumption while maintaining network functionality
3Speed
If devices wake up frequently to check for messages, then network responsiveness is improved, but network overhead increases
Solution Approach 1:
The patent structures network communication around periodic beacon transmit windows and discovery query windows, concentrating message exchanges into scheduled intervals to reduce continuous monitoring requirements and associated overhead while maintaining predictable network responsiveness
Solution Approach 2:
The patent performs preliminary configuration of window intervals and timing parameters before actual message exchanges, allowing devices to prepare for scheduled communication events in advance and reduce the need for continuous network monitoring
