Wireless Network Participation via Master-Generated ARP Tables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems require significant time to establish communication among apparatuses due to the need for inquiry and ARP processes, leading to delays in network participation.
Innovation Solution
A wireless communication system where one information processing apparatus generates and transmits a management table associating physical and logical addresses, allowing other apparatuses to receive and store this table, thereby reducing the time needed for communication initiation by eliminating the need for inquiries and ARP processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If each apparatus generates the management table by inquiring about GARP or ARP, then the address association is established, but the time required to start communication increases
Solution Approach 1:
The master apparatus generates and transmits the management table containing IP address and MAC address associations to slave apparatuses in advance, before communication is actually needed. This preliminary provision of address information eliminates the need for time-consuming ARP or GARP inquiries when communication starts, directly resolving the contradiction by preparing address associations beforehand.
2Loss of time
If the management table is transmitted from the first information processing apparatus to the second, then communication start time is reduced, but the device complexity increases
Solution Approach 1:
The master apparatus serves as an intermediary that centralizes the generation and distribution of the management table to all slave apparatuses. This intermediary approach simplifies the overall system architecture by consolidating address management functionality in one device, avoiding the complexity that would arise from each apparatus independently managing address resolutions.
3Productivity
If ARP or GARP inquiry processes are used, then address resolution is achieved, but communication efficiency decreases
Solution Approach 1:
The management table is transmitted as a complete copy of address association data from the master apparatus to all slave apparatuses. Each slave apparatus receives and stores this copied management table, enabling all devices to independently resolve addresses without performing ARP or GARP inquiries, thereby eliminating the time loss and improving communication efficiency.

AI summary
An example of a wireless communication system includes a master apparatus and a slave apparatus. Upon receiving a participation request from the slave apparatus, the master apparatus generates an IP address of the slave apparatus, generates an ARP table in which an IP address and a MAC address of the master apparatus are associated with each other and the IP address and a MAC address of the slave apparatus are associated with each other, and transmits the ARP table to the slave apparatus. The slave apparatus stores the received ARP table therein. When transmitting data to the master apparatus, the slave apparatus transmits the data to the master apparatus with reference to the ARP table.
