Reliable data streaming over delay tolerant networks

Data streaming over Delay-Tolerant Networks (DTN) is a challenging task considering jointly the specific characterisics of DTN environments, the demanding nature of streaming applications and their wide applicability. Presently, there are not any advanced mechanisms available to support this functionality and typical configurations fail to efficiently transfer data streams. In this paper, we present our ongoing work in data streaming over DTNs and propose the Bundle Streaming Service (BSS) as a framework to improve the reception and storage of data streams. Our proposed framework exploits the characteristics of Delay Tolerant Networks to allow for reliable delay-tolerant streaming. Here, we present a simple usage scenario along with the proposed framework and evaluate it experimentally at a preliminary stage which, however, suffices to demonstrate its potential suitability for both terrestrial and Space environemnts.
