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.
This paper presents the design of an RF front end for a base transceiver station implemented with a commercial general purpose software defined radio board. This front end helps to decrease the total cost of deploying community networks and the contribution of this paper is to disclose its project and simulation results, as well as discuss the aspects that influenced its design decisions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
