Abstract

Proposes the ISB (Improved Self-Pruning Based Broadcasting) algorithm — a reactive broadcasting technique that uses extended three-hop neighbour knowledge to dramatically reduce the number of forwarding nodes while keeping packet headers minimal. Simulation results show ISB outperforms both self-pruning and dominant pruning across all tested network densities.

Key Result

ISB reduced redundant rebroadcasts by up to 40% compared to classic self-pruning, while maintaining near-100% delivery coverage — demonstrating that three-hop knowledge is sufficient for near-optimal broadcast coverage in ad-hoc networks.
