ARP Spoofing Power Management for Battery-Powered Network Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent broadcasting of ARP packets by network security devices to maintain ARP spoofing can prevent battery-powered devices from entering a sleep state, leading to increased power consumption and reduced battery life, as these devices remain active and continuously monitor network traffic.
Innovation Solution
A private network device implements ARP spoofing by sending periodic ARP packets only to active client devices, suspending them when inactive, allowing battery-powered devices to enter a low power or sleep state and conserve battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If periodic ARP packets are continuously broadcast to maintain ARP spoofing, then network security is maintained, but battery-powered devices cannot enter sleep state and power consumption increases
Solution Approach 1:
The system dynamically adjusts ARP packet transmission based on the activity state of client devices. When a battery-powered device is detected to be in sleep mode, the network security device stops broadcasting ARP packets to that device, allowing it to maintain low power consumption. When the device becomes active, ARP spoofing is reinstated. This dynamic adaptation resolves the contradiction between maintaining continuous security and preserving battery life.
Solution Approach 2:
The system changes the transmission parameter (ARP packet frequency) based on the operational state of client devices. By monitoring device activity and adjusting the ARP packet broadcast interval from continuous to suspended state, the system optimizes both security effectiveness and energy consumption, allowing battery-powered devices to enter sleep mode when appropriate.
2Object-affected harmful factors
If ARP spoofing is implemented to intercept and filter network traffic, then security threats are detected and blocked, but battery-powered devices remain active and battery life is reduced
Solution Approach 1:
Instead of continuous ARP packet broadcasting, the system implements periodic action by only transmitting ARP packets when client devices are active. The network security device monitors device states and reinstates ARP spoofing periodically when devices wake from sleep mode, rather than maintaining constant transmission. This reduces battery consumption while maintaining security coverage during active periods.
Solution Approach 2:
The system extracts the ARP spoofing function selectively applied only to active client devices. By removing the continuous transmission requirement and applying ARP spoofing only when needed (when devices are awake and communicating), the system maintains security functionality while eliminating unnecessary battery drain during device idle periods.
3Reliability
If network security devices monitor all client devices to maintain ARP spoofing, then security coverage is comprehensive, but battery-powered devices consume excessive power
Solution Approach 1:
The network security device applies different ARP spoofing strategies to different client devices based on their activity states. Instead of uniformly maintaining ARP spoofing for all devices, the system locally adapts the security mechanism - suspending ARP packets for sleep mode devices and maintaining them for active devices. This localized approach ensures comprehensive security coverage for active devices while avoiding unnecessary energy consumption for inactive ones.

AI summary
A private network device such as a security device is inserted in a private network using ARP spoofing, which includes sending periodic ARP packets from the private network device to a router and to client devices to ensure the private network device spoofing remains intact. The private network device determines when at least one of the one or more private network devices is inactive, such as by monitoring the network for activity between the devices and a router, and suspends sending the periodic ARP packets to the client devices when they are inactive.
