Method and Device for Wireless Topology Discovery for Train Backbone Networks

Technology Overview: A wireless train‑backbone “inauguration” protocol that enables each backbone node (BN) to learn the ordered physical topology of a linear train network using directional antennas and hello/topology frames. The method includes pair‑consistency checks, local topology table updates, and topology convergence detection—adapting the wired IEC 61375 concept to wireless channels.

Industry Pain Point: Existing standards assume wired links between adjacent BNs; shifting to wireless faces broadcast interference, fading, and ambiguous neighbor identification, especially when consists are reconfigured.

NJIT Solution: Introduce a robust wireless TD protocol using directional reception and frame‑type logic to correctly identify left/right neighbors and converge to the true linear order, requiring only minor changes relative to wired procedures.

Key Features & Advantages

• Directional‑antenna pairing to disambiguate neighbors and mitigate interference.
• Pair‑consistency & convergence checks for reliable topology learning.
• Designed for dynamic train reconfiguration without manual intervention.

Development Stage: TRL 4 – Proof‑of‑concept with issued patent embodiments and analytical validation. ,

Target Markets

• Rail OEMs and system integrators (train control & comms)
• Industrial linear wireless networks (e.g., platooning vehicles)
• Standards‑driven transportation communications
