Delay/Disruption Tolerant Mesh Network Using LibreMesh and IBR-DTN

Abstract

The Wireless Mesh Network (WMN) allows communication between wireless devices with the aid of multihop wireless mesh routers, while they are within range of the radios, under penalty of data loss. But, long distances, delays, disruptions or disconnections between nodes are a challenge to Wireless Mesh Network. The DTN (Delay / Disruption Tolerant Networking) technology allows the transfer of continuous and quality data in a network, this technology has a data delivery guaranteed by its Store-and-Forward mechanism. This article presents a low-cost and easy implementation of a Delay/Disruption Tolerant Wireless Mesh Network, through WMN associate with DTN. For the easy and low-cost implementation, we use the tools LibreMesh and IBR-DTN, because they are free and have low complexity. The validation of the implementation was through an analysis of Packet Loss and Round Trip Time (RTT) between the Mesh Network with and without the DTN association.
