Wireless Packet Length Adjustment for Image Data Forwarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image data forwarding over wireless networks between image reading apparatuses and information processing apparatuses is hindered by fluctuating communication quality, leading to potential delays and difficulties in determining the availability of shared image reading devices among users.
Innovation Solution
Incorporating a wireless state detector and packet length determining module within both the image reading and information processing apparatuses to adjust packet lengths based on wireless state degradation, thereby reducing retransmissions and informing users of device availability through improved state recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image data is forwarded via wireless network, then convenience of use is improved, but communication quality fluctuates causing data forwarding delays
Solution Approach 1:
The packet length is dynamically adjusted based on real-time wireless communication quality detection. The image reading apparatus and information processing apparatus continuously monitor communication quality and adaptively change packet length parameters to optimize data transmission efficiency under varying wireless conditions.
Solution Approach 2:
The system changes the packet length parameter according to detected communication quality. When communication quality deteriorates, the packet length is reduced to minimize retransmissions and maintain efficient data forwarding, thereby reducing time loss while preserving wireless convenience.
2Adaptability or versatility
If multiple users share the image reading apparatus, then versatility is improved, but device availability recognition becomes difficult
Solution Approach 1:
The system implements feedback mechanisms where the image reading apparatus communicates its current state (busy/available) to connected information processing apparatuses. Users can receive real-time information about device availability through notification displays, enabling informed access decisions in multi-user environments.
Solution Approach 2:
The wireless communication system acts as an intermediary that transmits device status information between the image reading apparatus and multiple user terminals. This intermediary channel enables remote users to recognize device availability without being physically present at the scanner.

AI summary
An image reading system includes an information processing apparatus, an image reading apparatus, and a wireless network. The information processing apparatus includes a wireless state detector for detecting a first wireless state between the information processing apparatus and an access point in the wireless network, a wireless state information receiver for receiving, from the image reading apparatus, information of a second wireless state between the image reading apparatus and the access point in the wireless network, a packet length determining module for determining a packet length such that the packet length in forwarding image data obtained by the image reading apparatus to the information processing apparatus via the wireless network is reduced according to degradation in either the first wireless state or the second wireless state, and a packet length information transmitter for transmitting, to the image reading apparatus, packet length information corresponding to determined packet length.
