Dynamic Beacon Generation for Wireless Base Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks continuously generate beacons at fixed intervals, leading to unnecessary energy consumption, increased visibility to potential attackers, and inefficient use of resources, especially in low-traffic environments.
Innovation Solution
Implement a method where beacons are generated only when a station is connected or actively scanning, with specific wait times (tw0 and tw1) to determine when to start and stop beacon transmission, and only respond to probe requests from authorized stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beacons are continuously generated at fixed intervals, then network availability and connection monitoring are improved, but energy consumption increases
Solution Approach 1:
The beacon generation is made dynamic by switching between continuous generation mode (when stations are connected) and stopped mode (when no stations are connected), allowing the system to adapt its behavior to current network conditions rather than operating statically at fixed intervals
Solution Approach 2:
The base station uses feedback from connection status detection (via probe requests and connection establishment signals) to control beacon generation. When connection status changes, the base station adjusts beacon generation accordingly, creating a closed-loop control system that responds to network conditions
2Reliability
If beacons are continuously generated at fixed intervals, then connection monitoring is improved, but network security deteriorates
Solution Approach 1:
The beacon transmission is dynamically adjusted based on real-time detection of scanning stations. When no stations are present, beacon generation stops, making the network invisible to passive eavesdroppers. When stations are detected, beacons resume to maintain connection monitoring and support active scanning protocols
3Ease of operation
If beacons are generated at high frequency (100ms intervals), then connection setup support is improved, but resource efficiency deteriorates
Solution Approach 1:
Instead of continuous periodic beacon generation, the system uses conditional periodic action where beacons are generated at standard intervals only when needed (stations connected or scanning). When no stations are present, the periodic generation is suspended entirely, eliminating wasteful resource consumption during idle periods
Solution Approach 2:
The system uses feedback from probe request detection and connection status to control beacon generation timing. This feedback mechanism ensures beacons are generated at appropriate frequencies only when stations are present and need them, automatically adjusting resource usage to match actual network demand

AI summary
The invention, which relates to a method for the generation of beacons by a base station in a wireless communications network, consisting of at least one base station and at least one station, the beacons being generated repeatedly at time intervals, is based on the object of specifying a method with which the generation of the beacons can be tailored to needs, achieving a reduction of the energy demand and the emissions, and an improvement in the security. According to the invention, the object is achieved in that the generation of the beacons is started with a switching on of the base station and is ended after the expiry of a wait time tw0 in the event that no station is connected to the base station, and in that the generation of the beacons is started by a receipt of a probe request from a station of the communications network and is ended after the expiry of a wait time tw1 in the event that no station is connected to the base station.
