Wireless LAN Intermediary Relay for Resource and Security Trade-offs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in selecting between forming a new wireless network and connecting to an existing one efficiently, particularly in scenarios where security and resource consumption are concerns, especially when one device is already connected as a base station or client in Wi-Fi Direct communication.
Innovation Solution
A communication apparatus with a determination unit that decides whether to connect a second apparatus to the existing wireless network or establish a new network, using a reception unit to receive connection requests and an establishment unit to set up a new network if the determination is to avoid existing network usage, while ensuring secure communication by routing data through a reliable intermediary if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a new wireless network is formed between communication apparatuses, then direct communication can be established, but wireless resources are consumed
Solution Approach 1:
The patent introduces a base station as an intermediary device that relays communication between terminal stations. Instead of forming direct peer-to-peer wireless networks, terminal stations communicate through the base station, which acts as a mediator. This approach consumes wireless resources more efficiently while maintaining communication security, as the base station can manage and control the communication flow between terminals.
2Use of energy by moving object
If communication is performed via another apparatus in an existing wireless network, then resource consumption is reduced, but security problems may arise
Solution Approach 1:
The patent implements a determination mechanism where the base station evaluates whether to allow terminal stations to communicate through it in the existing wireless network. The base station receives communication requests from terminal stations, determines whether to permit relay communication based on security criteria, and provides feedback control. This feedback mechanism ensures that resource-efficient relay communication is enabled only when security requirements are met, resolving the contradiction between resource efficiency and security.
3Reliability
If a terminal station establishes a new wireless network, then secure direct communication is achieved, but device complexity increases
Solution Approach 1:
The patent designates a base station as an intermediary that manages network establishment and communication coordination. Instead of requiring terminal stations to independently establish and manage new wireless networks, the base station handles network formation, parameter configuration, and communication management. This intermediary approach maintains secure direct communication between terminals while reducing the complexity burden on individual terminal devices.

AI summary
A communication apparatus which performs communication in a wireless LAN by operating as a base station or a terminal station of the wireless LAN determines, if currently connected to the wireless LAN as the terminal station when receiving the connection request from a first another apparatus, whether to cause the first another apparatus to connect to the currently connected wireless LAN. Then, the communication unit communicates with the first another apparatus via a second another apparatus which operates as the base station in the currently connected wireless LAN when determining to cause the first another apparatus to connect to the currently connected wireless LAN, and communicates with the first another apparatus not via the second another apparatus when determining not to cause the first another apparatus to connect to the currently connected wireless LAN.
