Communication Apparatus Dynamic Cluster Selection for NAN Service Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a network environment with multiple Wi-Fi NAN clusters, existing communication apparatuses face challenges in efficiently managing power consumption while providing service notifications, as they need to transmit and receive signals in multiple clusters, increasing power usage and limiting their ability to selectively notify services to specific or all clusters.
Innovation Solution
A communication apparatus with a participation unit to join either a single or multiple networks based on predetermined values, a notification unit to selectively issue service notifications in joined networks, and a selection unit to choose the notification method, allowing for optimized power management and broader service notification coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a NAN device joins multiple NAN clusters to notify services in all clusters, then the service notification coverage is improved, but the power consumption increases
Solution Approach 1:
The NAN device dynamically switches between single-cluster mode and multi-cluster mode based on operational conditions. The device can adaptively join or leave clusters by comparing Cluster Grades and receiving switch notifications, optimizing the balance between service coverage and power consumption in real-time
Solution Approach 2:
The device changes its operational parameters by adjusting the number of clusters it joins based on Cluster Grade values and service requirements. When a higher Cluster Grade is detected, the device may leave its current cluster and join the new one, thereby changing its notification coverage parameter while managing power usage
2Use of energy by moving object
If a NAN device joins a single NAN cluster to suppress power consumption, then the power consumption is reduced, but the service notification coverage is limited
Solution Approach 1:
The NAN device employs dynamic cluster selection by continuously monitoring for higher Cluster Grades and switching clusters when beneficial. This dynamic behavior allows the device to maintain single-cluster operation for power savings while temporarily expanding to multi-cluster mode when service coverage becomes necessary
Solution Approach 2:
The device autonomously decides whether to expand service coverage by comparing detected Cluster Grades with its current cluster's grade. It self-manages the trade-off between power consumption and notification coverage by automatically joining or leaving clusters based on predefined criteria without external intervention

AI summary
A communication apparatus is provided and is capable of selecting between a mode in which a service notification is issued in a single network (NW) and a mode in which a service notification is issued in a plurality of NWs selects which mode to issue a service notification based on a predetermined condition, and issues a service notification based on the selected mode.
