Intellectual Property & Development status: US Patent Protection is pending.

NJIT is currently seeking commercial partners for the further development and commercialization of this opportunity.


Technology Brief:

Researchers at New Jersey Institute of Technology in the Department of Electrical and Computer Engineering have proposed a novel wireless topology discovery protocol that overcomes wireless impairments imposed by the broadcast nature of the wireless medium, and by fading and interference.


Topology discovery in wireless linear networks is a key enabling protocol for application such as wireless train backbone communication. The implementation of topology discovery over wireless channels is made difficult by the broadcast nature of the wireless medium, and by fading and interference. The invention for wireless topology discovery is on a physical implementation of the system that leverages directional antennas and frequency planning and overcomes wireless impairments. Additionally, the invented wireless topology discovery protocol requires minor modification to the current wired topology discovery protocol standard.



•       Wireless train backbone communication

•       Inter-vehicle communication systems



•       Overcomes wireless impairments such as broadcasting, interference and fading.

•       Robust performance

•       Easy implementation
