Wireless Relay Scanning Control via DHCP Load Translation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing data communication systems face inefficiencies and high costs due to the multiple DHCP server contacts required for wireless relay attachments, especially during mass attachment events like power outages, which lead to increased latency and load on the DHCP server.
Innovation Solution
A wireless relay controls its scanning and attachment process by translating DHCP server load or latency data into degrees-per-scan, allowing it to efficiently select and attach to multiple wireless access points, thereby reducing the number of scans and attachments, and optimizing the use of network resources.

Engineering Contradiction Analysis
1Reliability
If the wireless relay attaches to multiple wireless access points to obtain better service, then the service quality for user equipment is improved, but the load on the DHCP server and the time required for attachment increase significantly
Solution Approach 1:
The system performs preliminary scanning and identification of available wireless access points before actual attachment is needed. The master wireless relay maintains a pre-established list of candidate access points, so when new wireless relays need to attach, they can quickly select from the pre-identified candidates rather than performing full scanning and DHCP procedures from scratch, thereby reducing attachment time while maintaining service quality
Solution Approach 2:
The master wireless relay acts as an intermediary between new wireless relays and the DHCP server. Instead of each wireless relay independently contacting the DHCP server multiple times, the master relay consolidates attachment information and communicates with the DHCP server in a coordinated manner, reducing the total number of DHCP interactions and the time required for multiple attachments
2Ease of operation
If the wireless relay contacts the DHCP server multiple times to obtain IP addresses for each attachment, then the wireless relay can obtain necessary network addresses, but the DHCP server becomes expensive and time-consuming to use
Solution Approach 1:
Multiple attachment requests are merged into a single coordinated process. The master wireless relay consolidates attachment information from multiple wireless relays and performs a unified interaction with the DHCP server, combining what would have been multiple separate DORA message exchanges into fewer, more efficient communications, thereby reducing DHCP server resource consumption while maintaining ease of address acquisition
Solution Approach 2:
The master wireless relay performs multiple functions: it acts as a regular wireless relay for user data transmission, serves as a scanning coordinator for identifying access points, and functions as an intermediary for DHCP address allocation. This multi-functionality allows the system to reduce DHCP server interactions without compromising the ability to acquire necessary network addresses
Data Source
AI summary
A wireless relay controls wireless scanning in a wireless data communication network. The wireless relay scans to wirelessly attach to a source wireless access point. The wireless relay wirelessly receives a scanning code from the source wireless access point. The wireless relay translates the scanning code into an amount of degrees-per-scan. The wireless relay then scans per the amount of degrees-per-scan to wirelessly attach to additional wireless access points. The wireless relay wirelessly exchanges user data through at least one of the additional wireless access points. The scanning code could be Dynamic Host Configuration Protocol (DHCP) server load or latency data.
