Solution Overview
Problem
Electronic devices in neighbor awareness networking (NAN) clusters face challenges in quickly finding alternative clusters for service continuity, leading to potential service quality degradation and increased power consumption due to extended scanning cycles.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device increases the duration of the scanning cycle to search for another NAN cluster, then the reliability of finding alternative clusters is improved, but the power consumption increases
Solution Approach 1:
The patent divides the scanning task among multiple electronic devices within the NAN cluster. Each device performs scanning at different time points according to distributed scanning time points, segmenting the overall scanning process into parallel sub-tasks. This segmentation allows the system to maintain high reliability of finding alternative clusters while reducing the scanning duration and power consumption for each individual device.
2Use of energy by moving object
If the electronic device fails to search for another cluster while performing scanning, then the power consumption is reduced, but the service quality is lowered and service may not be performed
Solution Approach 1:
The patent implements preliminary action by having multiple electronic devices perform scanning at different time points before a service transfer is actually needed. The first electronic device determines second scanning time points for other devices in advance, and these devices perform scanning at these predetermined times. This preliminary distributed scanning ensures that information about alternative NAN clusters is already available when service transfer is needed, maintaining service quality while optimizing power consumption.
3Ease of manufacture
If the electronic device performs scanning at regular time cycles to search for another NAN cluster, then the systematic approach is improved, but the time required to find alternative clusters increases
Solution Approach 1:
The patent implements dynamics by making the scanning process adaptive and flexible rather than static. The first electronic device determines second scanning time points for other devices based on the first scanning time point and first cycle information, creating a dynamic scanning schedule. This dynamic approach allows the system to maintain systematic organization while significantly reducing the time required to find alternative clusters through parallel scanning operations at optimally distributed time points.
