Virtual Coordinator Scheduling for Wireless Power Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in power distribution, particularly in massive IoT environments where devices with surplus power cannot effectively share power with those that are insufficient, leading to low power utilization and limited battery-free device design due to limitations in wireless power transmission technologies.
Innovation Solution
A virtual power shared model is introduced, utilizing a virtual coordinator that registers and schedules power sharing between demander and supplier devices through wireless communication, allowing devices to redistribute surplus power efficiently and increase power use efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If wireless power transmission technology is used to enable power sharing between devices, then power utilization efficiency is improved, but device complexity increases due to the need for coordinator devices and scheduling mechanisms
Solution Approach 1:
A coordinator device is introduced as an intermediary to manage power sharing between supplier devices and demander devices. The coordinator receives power information from both suppliers and demanders, performs scheduling to determine power allocation, and coordinates the actual power transmission. This intermediary structure enables efficient power utilization while maintaining manageable system complexity through centralized control logic.
2Loss of energy
If power sharing scheduling is implemented to optimize power distribution, then power efficiency is improved, but communication overhead increases due to information exchange between devices and coordinator
Solution Approach 1:
Power information including supply capability and demand requirements is collected and registered in advance with the coordinator device before actual power transmission occurs. This preliminary information exchange allows the coordinator to pre-calculate optimal power allocation and scheduling decisions, reducing the need for continuous communication during power transmission and thereby minimizing communication overhead while maintaining high power efficiency.
3Ease of operation
If wireless power transmission is implemented without coordination, then device autonomy is maintained, but power distribution efficiency deteriorates due to lack of centralized management
Solution Approach 1:
The coordinator device serves as a mediating entity that enables autonomous devices to participate in efficient power sharing. Supplier devices and demander devices maintain their operational autonomy while the coordinator provides centralized scheduling and management functions. This architecture allows devices to operate independently while achieving coordinated power distribution efficiency through the intermediary's optimization algorithms.
