MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202531129676 A) filed by Guru Nanak Institute Of Technology, Kolkata, West Bengal, on Dec. 20, 2025, for 'fostering disaster management in coastal areas through cognitive radio based on spectrum aware opportunistic routing.'
Inventor(s) include Dr. Surajit Basak; Dr. Avali Banerjee; and Mr. Koushik Pal.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "A disaster-resilient spectrum-aware opportunistic routing system integrates cooperative spectrum sensing, probabilistic-interference-aware spectrum assignment, transmit power control and an outage-minimizing opportunistic routing (OMOR) algorithm on a real-time software defined radio (SDR) platform to autonomously restore multi-hop communications in coastal disaster-affected areas when conventional infrastructure is unavailable, wherein centralized convex-optimization-based optimal routing with closed-form power expressions and a low-complexity distributed OMOR variant are supported and validated by simulation and a prototype SDR testbed to reduce end-to-end outage, improve sensing reliability and enhance energy efficiency."
