Wireless Mesh Node Periodic ID Cycling for Power and Spoofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mesh network transmitters consume excessive power and are susceptible to spoofing, as they do not communicate with administrators and emit static identifiers.
Innovation Solution
Implementing a system where mesh network nodes periodically switch between broadcast and skip cycles, cycling new IDs to prevent spoofing and conserve power, while allowing communication with administrators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmitters emit static identifiers continuously, then spoofing susceptibility increases, but power consumption increases
Solution Approach 1:
The transmitter periodically changes its identifier instead of emitting a static ID continuously. This periodic action allows the system to maintain spoofing resistance through ID changes while reducing power consumption by not transmitting constantly. The identifier is updated at predetermined intervals, creating a balance between security and energy efficiency.
Solution Approach 2:
The identifier transitions from a static state to a dynamic state where it changes over time. This dynamic approach allows the transmitter to adapt its identifier periodically, preventing spoofing attacks that rely on static identifier prediction while managing power consumption through controlled transmission cycles.
2Loss of information
If transmitters communicate frequently with administrators, then status monitoring improves, but power consumption increases
Solution Approach 1:
The transmitter communicates with administrators periodically at predetermined intervals rather than continuously. This allows status information to be delivered reliably while significantly reducing power consumption by entering low-power states between communication cycles.
Solution Approach 2:
The system implements a feedback mechanism where the transmitter sends status information to administrators at scheduled intervals. This feedback loop ensures administrators receive necessary status updates without requiring continuous communication, optimizing the balance between information delivery and power consumption.
3Reliability
If transmitters operate continuously without skipping cycles, then network coverage is maintained, but battery life decreases
Solution Approach 1:
The transmitter operates in periodic cycles, alternating between active transmission periods and skip cycles where it remains in a low-power state. During active periods, network coverage is maintained; during skip cycles, power consumption is minimized. This periodic operation extends battery life while preserving essential network coverage functionality.
Solution Approach 2:
Instead of continuous operation, the transmitter performs partial action by activating only during necessary intervals. This partial operation mode maintains sufficient network coverage during active periods while significantly extending battery life through reduced overall transmission activity.

AI summary
Systems and methods for the periodic creation of wireless mesh networks are disclosed. In order to save power the nodes in the mesh network may periodically switch from being in a broadcast mode and a skip cycle. When in the broadcast mode the node may cycle broadcasting new IDs in order to prevent spoofing.
