Enhancing Bundle Delivery Efficiency in Mobile Ad-hoc Networks with a Multi-protocol Delay-Tolerant Network

Abstract

Mobile Ad-hoc Networks (MANETs) are challenged by highly dynamic network conditions like delayed or frequently disrupted communication. Traditional MANETs typically rely on a single Delay-Tolerant Network (DTN) routing protocol across all nodes, which can limit efficiency in unfavourable network conditions. To address this, our research introduces a dynamic approach, employing multiple DTN routing protocols concurrently within a MANET. Each node can adaptively operate on a distinct DTN routing protocol based on the prevailing network conditions. This strategy harnesses the strengths of each protocol while mitigating their limitations, resulting in a notable enhancement in the delivery ratio, as evidenced by simulations of different network scenarios. Comparatively, this multi-protocol approach outperforms single-protocol MANETs, as simulated by the Opportunistic Network Environment (ONE) simulator. The findings emphasize that a multi-protocol strategy enhances adaptability, robustness, and overall performance in MANETs, offering a transformative approach to wireless communication network management and operation.
