Ad Hoc Wireless Power Control via Master Station Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ad hoc wireless networks, existing power control methods fail to effectively manage transmission power, leading to increased power consumption or communication failures due to the lack of a master station to provide instructions for power control.
Innovation Solution
A communication apparatus and method that includes an information acquisition unit to gather information from communication partners, an electric power control unit to manage power consumption, and a control unit to determine when to execute power control based on acquired information, ensuring that only one device controls power to maintain efficient communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If autonomous transmission power control is applied in ad hoc network, then each wireless terminal can control electric power independently, but transmission power becomes excessively large or small causing power consumption increase or communication failure
Solution Approach 1:
The patent introduces a master station as an intermediary that coordinates power control decisions among multiple wireless terminals in the ad hoc network. The master station receives information from communication partners and determines which terminal should control transmission power, preventing conflicting autonomous control actions and ensuring stable communication.
2Extent of automation
If each wireless terminal controls transmission power independently, then autonomy is improved, but power consumption increases or communication fails
Solution Approach 1:
The master station acts as a mediator that receives information from communication partners and determines which terminal should control transmission power. This coordination prevents multiple terminals from simultaneously controlling power, reducing unnecessary power consumption while maintaining autonomous operation capability.
3Device complexity
If transmission power is controlled without coordination, then device complexity is reduced, but communication reliability deteriorates
Solution Approach 1:
The master station serves as a simple intermediary that coordinates power control decisions without requiring complex distributed control algorithms at each terminal. This centralized coordination point maintains communication reliability while keeping individual device complexity low.

AI summary
Communication apparatuses each having a power consumption control function acquires information of a communication partner apparatus to determine on the basis of the acquired information whether to use the control function of itself or to use that of the communication partner apparatus for controlling power consumption in a wireless communication network. The control function of the determined apparatus controls the electric power of the wireless communication.
