Network Device System Identification Module for Management Frame Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices in networks, such as IoT devices and smart devices, often receive unnecessary management frames that lead to battery drain and network congestion, as well as potential privacy risks from malicious or compromised systems.
Innovation Solution
Implementing a system identification module that determines whether management frames are from a homogeneous or heterogeneous system based on source addresses, signatures, and operational states, allowing devices to selectively respond and conserve resources while maintaining privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices respond to all received management frames, then network communication completeness is improved, but battery power is drained and network bandwidth is congested
Solution Approach 1:
The system performs preliminary identification of the transmitting device's operational state before responding to management frames. By checking whether the device is in a deep sleep mode or active state in advance, the receiving device can determine whether to respond, avoiding unnecessary battery consumption while maintaining communication reliability for active devices.
Solution Approach 2:
Instead of responding to all management frames universally, the system applies partial action by selectively responding only to frames from devices in active or light sleep states. This partial response strategy reduces energy consumption while maintaining sufficient network communication functionality.
2Reliability
If devices respond to all received management frames, then network communication completeness is improved, but network bandwidth is congested
Solution Approach 1:
The system performs preliminary identification of the transmitting device's operational state before responding to management frames. By checking whether the device is in a deep sleep mode or active state in advance, the receiving device can determine whether to respond, reducing network traffic from unnecessary responses while maintaining communication reliability for active devices.
Solution Approach 2:
Instead of responding to all management frames universally, the system applies partial action by selectively responding only to frames from devices in active or light sleep states. This partial response strategy reduces network bandwidth consumption while maintaining sufficient network communication functionality.
3Productivity
If devices respond to all received management frames, then communication responsiveness is improved, but privacy risks increase from malicious systems
Solution Approach 1:
The system performs preliminary identification of the transmitting device's operational state and legitimacy before responding to management frames. By checking whether the device is in a valid active state or potentially malicious in advance, the receiving device can determine whether to respond, reducing privacy risks from malicious systems while maintaining responsiveness to legitimate devices.
Solution Approach 2:
The system converts the potential harm of receiving frames from malicious devices into a benefit by using the frame analysis to identify and block malicious sources. The management frames that would normally trigger responses are instead used as identification signals to detect and prevent privacy attacks.
Data Source
AI summary
In aspects of homogeneous and heterogeneous system determination in a network, a device can receive a first management frame and a second management frame communicated in separate data messages using a common communication protocol. The device implements a system identification module that can detect the first and second management frames are communicated in data messages from a radio device. The system identification module can determine that the first and second management frames are communicated from a homogeneous system that includes the radio device based at least in part on source addresses included in the first and second management frames. The system identification module can then determine to associate with the homogeneous system based on an operational state of services associated with either the first or the second management frames.
